Secure CFIDE Virtual Directory
Hello Guys, Looking for your advice on the best way to create a secure IIS virtual directory to /CFIDE. My understanding is that certain folders within that need to web accessible for cfchart,cfform,cfdocument to work, is that correct? However I don't want to expose my /cfide/administrator and /cfide/adminapi to the wide world :-) or anything else which might post a security risk for that matter. What is the best way of doing this? I'm thinking about creating a copy of the CFIDE folder and calling it SecureCFIDE (or something to that effect), it contains only the required elements and not the admin panel etc, then creating a Virtual Directory link to that in the IIS sites that require it, does that sound like a fair idea? Which files are required? Cheers all, Rob ~| Want to reach the ColdFusion community with something they want?

Formatting HTML as Plain Text.
Hey Chaps, I've been doing a little work with some RSS feeds of late, and on the most part all is very well, now, the one problem I'm running into is people who publish RSS feeds containing lots of junk HTML (urgh!), like inline links, images, divs and whatnot in the description content of the feed. I only want to have the plain text version of these feeds and not all the other junk. This means stripping out the html tags div, a etc, some of which are being published as lt; and gt;. Also, I want to convert HTML formatted characters into their nice plain text equivilants, for instance making amp; just a standard . Now presumably this can all be done with REGEX (I couldn't find any nice built in CF functions) however my skills in this area are pretty much non-existent, however I know some of you are fairly experienced with this kind of thing. I'm also hoping that I'll be able to do some form of REGEX related 'find' on the rules first so I can say to the user 'this feed appears to contain lots of redundant crap, would you like it cleaned for you? this may cause formatting issues.' or something to that effect, I can then process the replace rules if they choose to do so. I'd appreciate any advice.

RE: Could not instantiate stub objects
Hey Kevin, Seems like the servers you've got setup are as identical as you could hope for, just seems to senseless that it wasn't creating them. Tell me, have you tried to the regenerate them again since you got it working? My only thought at the moment is that whilst not a permissions issue perhaps one of the old stub objects on the server has become corrupt and couldn't be overwritten by CF, yet you deleting is manually and then copying in the version from the production would be fine. Perhaps it's worth reclicking the 'refresh' button in the admin now to see what it does? Or deleting the stub objects manually and then running the code, that would give some more clues.

cffeed action when content changes.
Afternoon guys, I'm after a little implementation advice from you. I am looking to build a scheduled task on the server which runs every 10 minutes pinging frequently changed RSS feeds, the addresses of which are stored in a DB, using, the trusty CFFEED tag. The top [n] records from the feed are then taken and placed into an email and fired off to me. *n being a variable number of feeds differing with each feed. What I want to do is, when pinging the feed, get a count of how many of those top [n] stories has changed (title and description) since we last pinged the feed, the reason for this is that I want to perform one action if all [n] stories has changed and another if only a few of them has changed. At present the only the feeds address and the record count wanted [n] are stored the DB, presumably I'll need to store other data it the DB now to track what the feed consisted of when I last pinged it but want to store the minimal amount of data possible to perform the task, due to the number of feeds involved and the frequency of their changes. I'm open to all and any ideas at the moment.

RE: YIKES! I must let internet users write SQL queries for our database!
Hey Ian, My first thoughts on this would be to ensure that YOU keep total control over the actually SQL that is being run, if you're working with large sets of data (more than a few GB) than the performance problems which arise from poorly written SQL could likely cause you all kinds of beef ;-) and that's just assuming that people aren't hitting you with malicious code (which they will) Not only that but also having to keep an eye on the queries people are running to ensure your indexes and statistics are configured in a manner which keeps things efficient is also quite a task bleh, it'd be messy I'm sure. I'd suggest developing some form of data access API in the form of a web service or possibly with your own front end on it if that's what the use case needs which allows users access to data but means you can retain control over the actual SQL which is executed at runtime. I don't know the full details of your use case at the moment but if I was in your shoes my first thought would jump to publishing a webservice API which allows people access to the data. I think if you let users write SQL to work on your data you'll likely just end up wanted to kill yourself, genuinely! The performance and security risks involved are just so huge.

RE: CF Code to create AutoIncrement column MS SQL?
Hi Dawn, This is something which should be handled by the database. In a database where you have auto incrementing the primary keys it shouldn't be the applications responsibility to keep an eye on that, you should be doing simple INSERT statements and allowing the DB to do the work. In a SQL Server database, provided you're using SQL Server Management Studio to connect to the DB you can set the column to auto-increment by right clicking the table in the object explorer and choosing 'modify' or 'edit' then highlight the PK column and in the 'column properties' pane at the bottom expand the 'identity specification' section, you'll then be able to set the column to an identity and have it auto increment.

Hi: I have a customer whose programmer has vanished and he is trying to get his application back on line. I'm an intermediate CF programmer and I've managed to get everything working again except for one problem. His database is hosted - and somehow, when he restored his application, the fields in his database lost their autonumbering capability. I tried creating the next number right before the insert by getting the max value of the field and then adding 1 to it, and that works for the most part, but occassionally, we are seeing the old Violation of PRIMARY KEY constraint 'PK_TblTestAnswers'. Cannot insert duplicate key in object 'dbo.TblTestAnswers' - and I can't figure out why unless to users are somehow hitting the same page at exactly the same time and clicking submit. So the only thing I can think of to fix the problem is to recreate the autoincrment key fields somehow. Does anyone have any Coldfusion code to insert a new autoincrement key field in to a MS SQL table and then remove the old one? Or is there a way to modify a key field to autoincrement?

RE: YIKES! I must let internet users write SQL queries for our database!
Hi Ian, Ah you call that big ;-) Mine is at least an inch bigger :-p Well, that certainly makes a great deal more sense. Like you say the primary concern is to stop users from creating queries which kill the system. I think with some thought put into the construction tool this could certainly help. For starters, are the queries which the users run very varied? Or is it a very similar query each time which lets them specify parameters through the form? If it's the latter than placing constraints on the parameters to stop them querying for multiple years etc will go a fair way to achieving your goal. Secondly would be to assess the database and its capable performance and make it run the queries as efficiently as possible, I know from my own experience working with our reports database (currently about 11,000,000 rows and growing quite likely to grow to a similar size as yours within the next 12 months has shown me the benefits of good database administration. There are several key areas where performance can be gained. 1. SQL - Ensuring the queries written are optimized and achieving their goal as well as possible. 2. Indexing, having the correct indexes on your data can have a MASSIVE impact, for instance, we had statistical queries which caused similar problems you what you're seeing (slow running or crashing the server) and yet the addition of a single index means the query now regularly runs in less than a second :-D 3. Maintenance, keeping your databases maintained by rebuilding statistics and indexed, compressing the files etc, all helps benefit performance. 4. Hardware, ensuring that the box you've got the database is up to the job, where databases are concerned this generally means RAM and plenty of it, this saves the DB having to scratch the disk every time it needs data. I think that look at these kinds of measures would be a good starting point for you in making things feel a great deal tighter. I'd be keen to ensure that all that stuff is running firmly before worrying too much about the tools on the front end. As for the front end, it's all about who your users is an how regularly they want data, if it's a laymen who wants the data every now and then I would say a web service isn't a good idea as they won't benefit, however, if these are professional clients who could utilize the service to save them time coming and filling in forms then it'd be a great solution. Either way, with something ColdSpring you could create a really nice Service Layer for yourself and your nice front end and then with a couple of lines of code open that API up as well using remote proxies then you have the best of both worlds for very little effort. Does any of that make sense? I hope I'm not teaching you to suck eggs on the DB side of things, I just know from my own experience I assume that I'm reaching the limits of my system when expecting it to return records instantly and then suddenly someone shows me a neat trick that makes it happen.

RE: YIKES! I must let internet users write SQL queries for our database!
Yeah you're quite right here, this is certainly something to consider as a security net down the line, however my only worry would be that it doesn't solve the root of the problem which seems to be this poor database which is struggling under its own weight. I think by the sounds of things the application is having regular occurrences of slow performance which means he'd just be spitting errors at users all the time, if we can solve the core problem and then use this method to solve the odd one-off occasions when performance struggles we'll be onto a winner I think.

I forgot to mention an important consideration is to somehow control and mitigate query requests so that users don't tie up the database with a task taking hours and hours to process. It is already a batch processing system, where the users do not get the response immediately, but rather it is submitted to a que and then the user receives an e-mail with a ftp link to the resulting output files when their request is completed. But, more and more frequently a request is to large and|or complex and it ties up the que so that nothing can be done until such a time as a DBA can get in there and kill the process that is jamming up the system. If CF is handling the database access you can set a timeout on the query to prevent it from tying up the server? I honestly have never run into this specific situation, so I don't know how well that works, but the first thing I would test is if I could simply specify timeout=60 or somesuch in the cfquery and have it automatically error and exit early if the statement is taking too long.

RE: YIKES! I must let internet users write SQL queries for our database!
Hi Ian, That all makes a great deal of sense. I really feel you're onto the right track with the database tuning method, that'll be a great start, whilst this is a fairly heavy database, in this day and age it also isn't really THAT heavy and these slow running queries, crashes and batch processes really isn't something you should have to worry about, I'm sure they're all quite solvable. From a front end perspective I think that defining an API for data retrieval is really a key for you, if you can create a common interface for the data collection which allows people to specify parameters for the data, you can then build a front end app, be it HTML, FLEX, AIR or otherwise which allows users to access the data without you and the other developers having to interpret their bespoke requirements and build queries for them. This is really just building a reporting tool for them. Then, should you wish to open a web service up which would allow more experienced people/corporations to access the data then that becomes very easy because all you're doing is publishing a version of the same API you use for your application. This way you're able to meet everyone's requirements. And with this strictly documented and defined API there is none of the confusion about misinterpreting their requirements, if they get the wrong data it's their fault for specifying the incorrect parameters. Because DB tuning is all quite specific to the data you want to retrieve (and insert) I would first start assessing and designing the API, once you know what and how the data is going to be retrieved (I mean you know what the queries look like) then you can tune the database to meet that requirement. Furthermore once you're in that position you can also start thinking about query caching, views and things like that to further extend the performance of the system.

Database tuning is an important line item on my discussion list for this meeting. To expand on some of your points. First the system currently limits users to only selecting data from on year at a time as a stop-gap measure to try and limit the operating cost of the query. The trouble is that this is both too limiting and not limiting enough. First it is still quite possible for a user to build a query that will jam up the system while at the same time it limits users who want specific enough information to be reasonable, but want it for multiple years. It forces them to submit the same request over and over only changing the year. Speaking of these users, they are truly a mixed bunch. They range from the professional who supposedly knows what they want to the soccer parent who wants to know *everything* that has been used withing a 100 mile radius of their home/work/school. Unfortunately we have to cater to both as best as we can. A big driver for making this as self-help as possible was the realization that we where commonly getting these requests from both sides of a litigation case in civil court. But because of how each side might have asked for the information combined with how different developers might have understood the request and the data we could be providing radically different results to each side that is effect provided some sort of de-facto 'interpretation' of the data. A position we really do not want to be in. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:321882 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: YIKES! I must let internet users write SQL queries for our database!
Yeah it sounds like your typical legacy type systems that's a little out of date. You might not even need to normalize the data, there's a lot to be said for performance if the data is denormalized and flatter, it's a balance you'll have to find. If you look back through all the requests you've had over the past couple of years you'll be able to build a pretty strong set of use cases for the interface, that'll help you understand what data you want out of the system, then a good investment will be with someone who knows SQL like the back of their hand, they'll then come in and write queries and tune the system to perform sweetly for you. Keep us posted on the progress you make, I'm sure I'll learn just as much from it as you do. Rob -Original Message- From: Ian Skinner [mailto:h...@ilsweb.com] Sent: 23 April 2009 18:12 To: cf-talk Subject: Re: YIKES! I must let internet users write SQL queries for our database! Yeah, the three main ideas I have developed so far are 1) database tuning, 2) API/Web service 3)Possible go to Flex after the first two. I agree that we are living with some unnecessary complexity. A good deal of this process was developed in the 90s when databases and servers were not nearly as powerful as they are now. A great deal complexity was built to try and mitigate the limits of the systems back then. I suspect we could simplify and normalize the system and then tune it properly and get a great deal of performance improvement.

RE: Could not instantiate stub objects
Hi Kevin,
In the admin panel when you click 'refresh' next to the webservice, what
happens then? Also, try running the following code in a CFM and see what
exception is thrown:
cfset CreateObject(java, coldfusion.server.ServiceFactory
).XmlRpcService.RefreshWebService('URL OF THE WSDL GOES HERE') /
That will likely throw the exact same exception as before, my only thought
if that doesn't work is that we can try and restart the cfusion service to
clear any dud caches it might be storing but other than that I'm all out,
unless the problem lies at the server end for whoever is publishing the
service, it'll be worth speaking to them if none of these things help.

turned down
upon many requests. So I'm stuck with CF 7. I know it is not
supported to
run JDK 1.6, but I need many of the features that come with that JDK
so
falling back also isn't an option.
The weird thing is that this has worked for quite some time and then
broke
out of the blue without any changes being made.
I would appreciate any suggestions on what could be going on.
Thanks,
Kevin

RE: Could not instantiate stub objects
Hi Kevin,
Yeah these kinds of issues are a nightmare, web services seem to always
throw really dumb vague errors which nobody knows anything about! I've
wasted hours on problems like this.
My final shot at this would be to delete that entry in the cfadmin and
restart the coldfusion service on your box, this should clear out any
temporary files. My thoughts at the moment are that the publisher has made
some changes to the service and that the WSDL is now invalid but due to some
cached file somewhere it won't refresh it properly or something.
If this isn't a really busy server and you can afford to restart it then
that would be my final suggestion, other than contacting the publisher to
see if they're aware of any issues.
The only other thing I wanted to ask, when you say you're browsing to the
WSDL in a browser and it works fine, is that on your local machine or in the
browser on the server? I'd be interested to know if the WSDL loads ok in the
browser on the server, might be some firewall setting or something causing
the problems.

Re: CFQUERY Timeout for SQL2005 Fails
This is an interesting thread, I've seen what I believe to be very similar behaviour here on one of my webservices, seemed that one particular query sometimes just hangs indefinitly, however other threads and requests are all just fine. I tried playing around with application request timeouts, concurrent threads and cfquery timeout settings but seem to still have the same problem on occasion, I'm wondering if they're caused by the same issue, I too running SQL2k5 however I'm on CF8. Mark, I'd concur that its waiting to establish a connection, is there anything which can be done to cure that problem with a timeout on the connection? I'd imagine mine is down to load as its a busy statistical database which we're having problems with which really needs moving to a beefier box but in the mean time it'd be nice to try and find a quick-fix to tide me over. Rob That's totally separate issue. if sqlserver is locking up, coldfusion is waiting to make a connection, not getting the result back. the timeout on cfquery only works on the actually sql statement itself. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:321611 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: SQL server - Order totals by month, even without month data
Hello Will, I'd advise building yourself a calendar table, these are always a useful facility in any application where you're going to be doing report generation, I've attached the SQL script which creates and populates your calendar table, this basically creates a record for each date in a range and breaks into different date parts, then for your query below we select the dates from the calendar table, ensuring we get a record for each group, be it day, month, year etc and then we'll LEFT OUTER JOIN the order table on that date, this ensures we get a row for every date in the range and it'll just return NULL for the months where orders don't exist. SQL CREATE Script: http://pastebin.com/m57ba4578 SQL INERT Script: http://pastebin.com/m65d6ee0f That script will create a table and insert records for the next 10 years, change the dates on the insert script to suit your own requirements.

RE: JRun Throwing 503 Errors
Yeah thought that would be the case. So, are they just slow running or was the end server not responding and causing them to stack? Did changing the concurrent requests setting the Admin help at all? Or just prolong the problem? I'd probably recommend using the timeout on cfhttp be set to solve this issue, at the moment it just sits indefinitely. Value, in seconds, that is the maximum time the request can take. If the time-out passes without a response, ColdFusion considers the request to have failed. If the client specifies a time-out in the URL search parameter (for example, ?RequestTime=120) ColdFusion uses the lesser of the URL time-out and the timeout attribute value; this ensures that the request times out before, or at the same time as, the page. If the URL does not specify a time-out, ColdFusion uses the lesser of the Administrator time-out and the timeout attribute value. If the time-out is not set in any of these, ColdFusion waits indefinitely for the cfhttp request to process. That won't solve the problem if they're just slow to return a large set of data however it'll solve the problem if you've got requests that are not responding.

RE: JRun Throwing 503 Errors
Matt, Hope you're well mate. With regards to this it looks as if requests are timing out whilst sat in the request pool before being processed. My guess would be that this might be related to those scheduled tasks, if they're running and consuming all available requests due to the slow running speed and creating a bottleneck then you'll be quing other requests for too long and causing them to time out. Try bumping the number if simultaneous requests up and see if that solves the problem, if it does then I'd look at making those scheduled tasks more efficient.

Re: Dynamic SubDomain Creation / Domain Pointing
Hello Chaps, We've been working on some ideas for our new reseller panel and one things which really attracts me at the moment is making the panel they sign-in to brand able. I've started so I'll finish ;-) I had an itchy trigger finger this morning. Now in the most part a brandable panel is very simple, allowing users to change the colour scheme, logo and headings in the site is all no problem at all. One thing I have seen done in other applications is the dynamic creation of a subdomain for each user which registers on the server, they can then access the login for that site from that domain, for instance, someone comes and registers with me, and they then have access to their branded panel through thiername.thinkbluemedia.co.uk and they don't have to come through our site. Not only this but they can also mask that subdomain with their own domain such as control.resellersdomain.com or whatever it might happen to be making things even more seamless for the clients which they are reselling too. Now I would assume that the latter part requires them to add CNAME records to their own DNS records and is out of my control, however, the first part is not. How would you guys go about creating these subdomains? presumably I don't want to actually create records in my own domains DNS settings as these would take 72 hours to propagate so can I perhaps do this with some type of URL rewrite? or perhaps a wildcard subdomain and I then use server side code CGI scope variables to to display the correct branding?

When running the query from SSMS it returns the dataset in less than a second, which I'm more than happy with and kind of confirms that the query itself, the database and the table indexes are all correct. However, when I run the same query from a cfquery block it takes 8 minutes to return!?!!!?! I also ran some tests where I would start the ColfFusion page request and then jump into SSMS and run the query from there at the same time, the query continued to return in less than a second in SSMS but still sat for upto 8 minutes before returning to CF. There are a bunch of other queries on the page, all of which run exactly as I would expect them too, just this one single query which is massively under performing. I can confirm that this performance decrease is not caused by slow rendering or anything as the 8 minute time is taken from the 'execution time' of the query displayed in its cfdump. Any suggestions as to what might be causing this beef?

Re: Coldfusion killed my query?
Morning Adrian, thanks for getting back to me. This is definitely not caused by the output/dump of the queries, even when all those are removed it takes the same amount of time to return the page. This is not a large query to return, simply a single row containing 2 columns. The query looks as follows: Select Sum(Case When d.LogClassName = 'org.thinkblue.TransferComplete' Then 1 Else 0 End) As SuccessSentCount, Count(Distinct d.Device_ID) As UniqueDevicesCount, Sum(Case When d.MinDate Is NULL Then 0 Else 1 End) As FirstAppearanceCount From( Select MessageLog.Device_ID, FirstAppearance.MinDate, LogClass.Name As LogClassName FromMessageLog Inner Join LogClass On LogClass.LogClass_ID = MessageLog.LogClass_ID Left Outer Join ( Select Device_ID, Min(LogDateTime) As MinDate FromMessageLog Inner Join LogClass On LogClass.LogClass_ID = MessageLog.LogClass_ID Where LogClass.Name In ( 'org.thinkblue.TransferComplete', 'org.openobex.Error.ConnectionRefused', 'org.openobex.Error.Forbidden', 'org.openobex.Error.NotAuthorized', 'org.openobex.Error.ConnectionTimeout' ) AndMessageLog.ThinkTank_ID = cfqueryparam value=#ARGUMENTS.ThinkTank_ID# cfsqltype=cf_sql_integer / Group ByDevice_ID ) As FirstAppearance On MessageLog.Device_ID = FirstAppearance.Device_ID And MessageLog.LogDateTime = FirstAppearance.MinDate Where LogClass.Name In ( 'org.thinkblue.TransferComplete', 'org.openobex.Error.ConnectionRefused', 'org.openobex.Error.Forbidden', 'org.openobex.Error.NotAuthorized', 'org.openobex.Error.ConnectionTimeout' ) And MessageLog.LogDateTime = cfqueryparam value=#ARGUMENTS.StartDate# cfsqltype=cf_sql_date / And MessageLog.LogDateTime cfqueryparam value=#ARGUMENTS.EndDate# cfsqltype=cf_sql_date / And ThinkTank_ID = cfqueryparam value=#ARGUMENTS.ThinkTank_ID# cfsqltype=cf_sql_integer / ) As d Like I say, the query actually runs fine from SSMS but just not when run from CF. Cheers, Rob To make sure it's not the display/debugging causing the issue, remove it all. A dump of a large query in Firefox with Firebug will take a while (I'm not saying 8 minutes, but a while!). Post the query too.

Re: Coldfusion killed my query?
Hello Guys, Thank you all for your ideas. After speaking with [Justice] over on the IRC channel I removed the cfqueryparam / and found it ran smooth as silk. Seems that there was some form of datatype mismatch going on, after changing the cf_sql_type on the queryparam we've got it running at proper speed again!! Thanks for your suggestions. Rob Another thing to try: put the query in a sproc and call it with cfstoredproc. Theoretically, modern SQL Server has made it so that cfquery (ad-hoc) is as fast as cfstoredproc...but...maybe... Let us know...

cfchart in cfdocument.
Guys, I've got a cfchart which sits inside a cfdocument. In development on my local machine this works perfectly, however, when moved to production we just get a red [X] where the chart should be sat. I've had this problem for as long as I can remember but have only got around to tackling it this morning. After doing some reading around it has become apparent that cfdocument obviously cant access the chart image on my production server which is why it inst displayed, my challenge is finding out WHY it cant access that resource. Nothing springs to mind as a configuration mismatch between dev/production but for some reason it only works on one. Can anyone give me some pointers on solving this?

Re: cfchart in cfdocument.
John, Thanks for the reply. chchart outside of the cfdocument works just fine, no problems at all, its only when placing it inside that it doesn't work :-( Rob If you do it without the cfdocument so that the chart would appear in the browser, does it still show as a broken image? If so, can you right-click the broken image and pull up the image location? That'll (at least) tell you where that page *thinks* the chart should be...

Loading data from a webservice call into MSSQL.
Posted this yesterday but seems to have disappeared and not come to the list :-s Afternoon Guys, I publish a web service which receives statistical data in an array of complex objects from clients. This data then gets processed and inserted into a SQL Server db to be reported from at a later time. Iâve been having a few issues in the past with deadlocks on the server because the import process isnât very efficient and is locking sql resources for too long, this hasnât been a major issue however with recent growth within the business and an increase in our client base weâre seeing it more and more regularly and I want to nip it in the bud before too long. Regards to loading of data, weâre looking at around 50 clients, each client makes a request once every minute, posting around 10 records per request, with a maximum of 100 records per request. Without getting too specific at this stage, the current import process in the web service function looks somewhat like this: !--- Start the transaction --- cftransaction !--- Create the temporary memory table. --- cfquery name=LOCAL.qCreate datasource=MyDSNName CREATE TABLE #MyTempTable /cfquery !--- Loop over the array of complex objects and populate the temporary table. --- cfloop from=1 to=#arrayLen(ARGUMENTS.Statistics_Data)# index=LOCAL.i !--- Load the data into the temporary table. --- cfquery name=LOCAL.qLoad datasource=MyDSNName INSERT INTO... /cfquery /cfloop !--- Load the data from staging into the first table if they donât already exist to ensure FK's exist for the primary table insert. --- cfquery name=LOCAL.CreateFKs1 datasource=MyDSNName INSERT INTO FkTable1 ( SELECT col1 FROM #MyTempTabl /cfquery !--- Load the data from staging into the first table if they donât already exist to ensure FK's exist for the primary table insert. --- cfquery name=LOCAL.CreateFKs2 datasource=MyDSNName INSERT INTO FkTable2 ( SELECT col1 FROM #MyTempTabl /cfquery !--- Load the data into the primrary table --- cfquery name=LOCAL.InsertPrimary datasource=MyDSNName INSERT INTO PrimaryTable ( SELECT FkTable1.id_col, FkTable2.id_col, #MyTempTable.SomeColumn1, #MyTampTable.SomeColumn2 FROM #MyTempTable INNER JOIN FkTable1 ON FkTable1.col1 = #MyTempTable.col1 INNER JOIN FkTable2 ON FkTable2.col1 = #MyTempTable.col1 /cfquery !--- Cleanup the oppertation by dropping the temporary table. --- cfquery name=LOCAL.qCleanup datasource=MyDSNName DROP TABLE #MyTempTable... /cfquery /cftransaction Now, what I hope you can see from that example is that I first create a temporary staging table for the data which is to be loaded, I then loop over the array of complex objects passed to the service method and populate the temporary table with them. I then have a couple of queries which insert any records which donât already exist into the two FK tables. These FK tables are then referenced in the main data import. Finally the temporary staging table is dropped. Would you guys handle this challenge in the same way? If you have regular request from multiple clients with data which had to be prepared and saved like this how would you go about it? My key concern is efficiency, I want the final solution to be scalable so as we grow the client base itâll continue running. Iâm just not sure of my best approach at the moment, am I running along the right tracks? Or should I be taking a totally different approach? Iâm sure this is a fairly common task so look forward to getting a little advice based on your experiences.

Re: Loading data from a webservice call into MSSQL.
Afternoon Adrian, thanks for getting back to me. Let me try and explain a little about what the temp table is used for. Basically lets use an example database schema for this, for now let's say we have two tables: Manufacturer Manufacturer_ID Manufacturer_Name Products Product_ID Manufacturer_ID Product_Name Now, for an example of the data which comes in from the web service call in the complex objects: Product Name: Manufacturer Name: iPodApple iPhone Apple Tastey Cake Grandma Now, product names that are posted are always new and never seen before, however, the manufacturer of the product may or may not already exist in the database. So, I load the data from the complex objects into the temporary table which mimics that structure, the first query then checks to see if any new manufacturers exist in the data which has been posted, if they have then it inserts them so they can be references as a FK in the products table when they are inserted by the final query. Does that make sense? I hope thatâs a clear example. Many thanks, Rob Each of those cfqueries is a separate call to the DB, could you wrap it all in one cfquery and see if it makes a difference? Why are you using the temp table for? Explain that a bit more as it might not be the best way or needed at all. Seems awfully complex code for the problem you're describing.

Re: Loading data from a webservice call into MSSQL.
Hi Sam, You should be able to create an in memory query to represent the received data (your temp 'table' is rows and columns, same as a 'query'), and then your other operations would proceed normally with a few minor changes in syntax, change the datasource= to dbtype=) Ok, so you're suggesting that I use an in memory query instead of the temp table, that's fair enough. So, are you suggesting a ColdFusion query? or a SQL Variable such as @TempTable? What are likely to be the performance limitations on larger datasets? say I want to up the post limit to 500 records per request from a client, will this hold up do you think? this would remove all the disk I/O and locking for the temp table, and make this db access truely concurrent(well writes to the REAL tables still invoke locking). You can use the caching options to help protect against outage I would expect. what are the design constraints about losing one of the updates in the event of a crash? That sounds fair about the disk I/O, we have contingency built into the client applications so that if an exception is thrown by the web service then the client will reattempt to upload the records in its next request so the odd error every now and then is not essential but I'm looking to limit it as much as possible.

Re: Loading data from a webservice call into MSSQL.
Hi Sam, Oh, and the relative lifetime of these objects drops significantly as well. the disk table is going to last for LOTS of milliseconds (10ms per I/O at least, times too many to count). here you won't incur ANY I/O unless paging gets involved. so you reduce the elapsed time by orders of magnitude for these table operations as well, if you have just 10ms of CODE to populate the in memory table it would be a HUGE table).. not to mention all the I/O impact on the real table. disk arm movement, blah blah. (and impact on the sql system buffering, cache flushes, etc.. ) Sam All this certainly sounds promising, minimizing the locks on the resources should solve the problems I've been having, very cool news indeed. Now, I'm not used to working with QofQ's at all, can you provide a little example of how I can query the in memory query and populate my real life tables with it? For instance my current queries using the temp table look something like: INSERT INTO RealTable (col1, col2, col3) SELECT Col1, Col2, Col3 FROM #TempTable How can this be reworked to draw from the in memory query opposed to the temp table? Thanks Sam, once I've got this I'll do some load testing and see how she holds up.

Guys, Quick buzz for some advice. I've just rolled a copy of my application onto the production server and cfdocument seems to not load any external resources such as images or css. The code works perfectly in development. The only thing that comes to mind for the moment is that the site is under SSL which I know can cause the kind of problems with cfdocument however I'm linking to the document using a non secure URL, such as: http://www.mydomain.com/myfile.cfm?format=pdf All the resources such as images and css within the document are sourced using relative paths like img src=/images/pullyourthumbout.png /. I've also tried making these paths a more absolute version, using src=http://mydomain.com and get the same result, and again, using the new cf8 localurl=true approach doesn't seem to change anything.

RE: SVN in Production
This is an interesting conversation, I've been using SVN Export for some time now when looking to deploy changes to production and not really had any beef from it. I understand what you guys are saying here about only wishing to deploy certain changes, that's a very valid use case, but to be honest, I would perhaps suggest that you guys are not strict enough on your version control in the first place and perhaps you processes rant quite right, as it sounds like you're deploying code straight from trunk / branches? Using your DIFF based stuff to pick and choose which modifications get deployed? Surely, once you know what code version is 'production ready' then you build it into a release candidate in a new tag? You then can use SVN to deploy from the latest tag to production? No? I wouldn't ever deploy from anything that wasn't in /tags, and the only way anything makes it into a tag is when its test and ready as a release candidate. -Original Message- From: Joeri B [mailto:[EMAIL PROTECTED] Sent: 11 August 2008 10:58 To: CF-Talk Subject: Re: SVN in Production Yes, indeed.

RE: SQL injection attack on House of Fusion
Rick, That might be a slightly off angle analogy. If a girl asks to be raped, then she is clearly consenting to the act and therefore it's not technically rape any more, that's the real world equivalent of building a server and publishing open source software for download, then complaining that someone 'stole' it. A better analogy is back to leaving the house door unlocked, it still doesn't change the fact that a criminal act has been committed, the burglar still takes your positions without consent, and the burglar would still be found guilty for it, however, I suspect your house insurance wouldn't pay out for the loss.

Afternoon Greg, I've done my fair share of SMS and MMS messaging in the past from cf applications. You should'nt need any JAVA work arounds however I would definitly stear clear of the cfmail route, people have reported many problems about that in the past, ol' Ben did a good job of pointing those out in that blog post. You need two things to get yourself running: A) An aggregator. This is a service provider who will send the messages to your recipients. B) The cfhttp tag. This will allow you to hit the aggregators webservices and make your requests to send messages. For MMS messages you usualy have a field which contains a base64 encoded binary data of the file you're looking to send, this can be gotten using simple cffile reads and the toBase64() method. Do some googling around for SMS aggregators, there are many to choose from and they usualy offer a free trial with 10-20 message credits for you to play around with. They will also offer a bunch of different communication methods so you dont have to use cfhttp if you dont want.

Re: MMS in ColdFusion?
Hello Guys, When working with it I was simply sending http POST requests to my aggregators web service, it was a very simple REST service. By the looks of things its all grown up in the past year with some people using MM7 which appears to be an iterface built on SOAP, so instead of using a REST service and the standard cfhttp tag you'd have to look into using cfinvoke to call it... however, and here is where I think Rick has more experiance than me, some data is sent using SOAP attachments which are currently not supported by the standard cftags, so you would need to look at using one of the JAVA webservice libraries. I'm sure you will still find aggregators which give you the basic REST service to post to, they can then do the complicated work of making the MM7 protocol calls to the service providers.

Another great little idea is delivering the files using cfcontent which means they don't have to be web accessible, this is a very nice security factor, I like it a great deal.

The image files are obviously much smaller than media files (mostly less than half a meg), but I can tell you that you are on the right track thinking that it is a resource intensive way to go. If we were doing larger files we would probably use something much dumber than a web service (also as you suggest) - a URL to retrieve the file via HTTP. Of course you can pass a token or something that is good for only 1 retrieval and then serve the file from a location outside the web root (for security). You could also zip it. But after zipping and using cfcontent and checking credentials you now have a second request that could be resource intensive as well. The bottom line is that there is no great low resource way to securely send files around in an SOA type architecture. -Mark Mark A.

The webservice isnt a standard ColdFusion webservice running over SOAP, this is a custom REST service which simply recieves POST data into the FORM scope and then spits back an XML document for the client to read. Now, I basicly offer a bunch of multimedia content over this webservice, anything from text, through to images, sound and video. With the current setup, when a request is made to the service for a particular piece or set of multimedia, the media is zipped on the server into an archive file, the binary data of which is then read into a base64 encoded string and this is then passed back to the client wrapped in some XML over the web service. The challenge I meet with this is not knowing how to weigh up the cost of bandwidth and security against the load hit this causes on the server. See, at the moment, with zipping the content I'm saving a substantial amount of bandwidth, also with zipping the files and sending them as a string I have the ability to be able to produce a HASH key checksum for the file, then when the file arrives the other end, the client can rebuild the file and checksum to make sure all is alive and well after the transmition. Now, the real downside to this option is that it must be hungry on the system, all the checksumming and zipping must be making some form of performance hit, right? especialy on what will likely become a very busy little web service in the comming months. My other planned method of attack is to not pass the files through the webservice at all, but simply pass a web accessible path for them, the client application could then simply loop through the returned XML and make http requests to download the media, this would obviously up the bandwidth but does offer less load involved with compressing the media. I'm sorry the question isnt a little more specific about what I'm asking, I'm just thinking out loud really, hoping somone will chime in and offer thier thoughts. How would you tackle this challenge? what would your priority be? bandwidth or reducing the load on the server? is it plausable to offer a checksum solution even if we're not sending the binary data over the service directly so we can still offer that level of security without the overhead of the zipping? I'm looking for the best ballance. I'd be interested to get your thoughts.

RE: Sending File Data Over Webservice
Thanks Dave, Unix? What's that? Heh, I'm only pulling your leg, I know what Unix is. I thought that cfcontent would be an intensive little monkey, it doesn't surprise me to hear you've found that in the past, it's nice to have that confirmation. I think my real goal with this is to keep it as unintensive as possible, I mean, keeping the files hidden from web access isn't the absolute end of the world, if people view and download them it has no real consequence, other than eating all my bandwidth, however, all the files are stored with a UUID as the name so it's not as if people will stumble across them by accident. One thing I'm considering as an option at the moment is maintaining the theory of passing the binary data back over a webservice, however, cutting out the compression, at least this makes the load on the server a little less and it's just the bandwidth which is going to take a bit of a hit, maybe 10-20% or something like that, quite manageable though. What do you think, does that sound a solution? Or would you still look around at the idea of making files temporarily accessible?

The webservice isnt a standard ColdFusion webservice running over SOAP, this is a custom REST service which simply recieves POST data into the FORM scope and then spits back an XML document for the client to read. Now, I basicly offer a bunch of multimedia content over this webservice, anything from text, through to images, sound and video. With the current setup, when a request is made to the service for a particular piece or set of multimedia, the media is zipped on the server into an archive file, the binary data of which is then read into a base64 encoded string and this is then passed back to the client wrapped in some XML over the web service. The challenge I meet with this is not knowing how to weigh up the cost of bandwidth and security against the load hit this causes on the server. See, at the moment, with zipping the content I'm saving a substantial amount of bandwidth, also with zipping the files and sending them as a string I have the ability to be able to produce a HASH key checksum for the file, then when the file arrives the other end, the client can rebuild the file and checksum to make sure all is alive and well after the transmition. Now, the real downside to this option is that it must be hungry on the system, all the checksumming and zipping must be making some form of performance hit, right? especialy on what will likely become a very busy little web service in the comming months. My other planned method of attack is to not pass the files through the webservice at all, but simply pass a web accessible path for them, the client application could then simply loop through the returned XML and make http requests to download the media, this would obviously up the bandwidth but does offer less load involved with compressing the media. I'm sorry the question isnt a little more specific about what I'm asking, I'm just thinking out loud really, hoping somone will chime in and offer thier thoughts. How would you tackle this challenge? what would your priority be? bandwidth or reducing the load on the server? is it plausable to offer a checksum solution even if we're not sending the binary data over the service directly so we can still offer that level of security without the overhead of the zipping? I'm looking for the best ballance. I'd be interested to get your thoughts.

Hi, Robert... and happy new year! Your issue with the rich cftextarea and the file uploads sounds exactly like what happened with me. The solution for me was to further modify the config.cfm file (FCKeditor\editor\filemanager\upload\cfm\config.cfm) on line 30. I had to change the config.serverPath value to a hard coded value, since FCKeditor isn't running directly off the root of the application using it. I found notes concerning this one line 30 of that file. I stumbled upon them while looking for a solution to the same problem you seem to be having. You also have to change the config.serverPath value to the same value as above for the config.cfm file in FCKeditor\editor\filemanager\browser\default\connectors\cfm\config.cfm. If your situation meets the criteria for changing the config.serverPath as mentioned on line 30 of both the config.cfm files mentioned above, trying hard coding the config.serverPath to a local system value such as E:\inetpub\webroot\userfiles\ or whatever path leads to the userfiles folders you're using.

Version Controll with IIS
Hello Chaps, I know many of you are running SubVersion for your version control on your Apache based servers, and to be honest I think its about time I got up and running with some proper source control, the number of Projects I have 'on the go' is growing and I need to tidy up my management a little bit before it start getting out of hand. After spending some time looking around it seems as if SubVersion only runs on Apache, which is fair enough I supose, however, I'm currently running on IIS6. I could upgrade or swap the web server over to Apache, but to be honest this is not in the slightest bit desirable as I dont want to play with my production environment like that. Is there a decent source control solution available for IIS? after hunting around nothing jumped out at me. Can I perhaps run Apache alongside IIS purely for the version control access? I'd really appreciate some pointers. If so, then how? I've also got a couple of questions about the way in which version control works. Currently I develop on my local network (I have a test server setup here). Then, once I'm happy that the code is running neatly I SFTP a copy up to the server and it becomes live on production. Does VersionControl replace that requirement for SFTP? From what I've seen of other SVN and CVS servers, when I want to start working on the code I 'check out' a copy into my Eclipse, Then work on it. How do I then republish my changes to the server? Is that somthing that SVN and CVS handle for me? I'm really after some tips and tricks on how to manage my project efficiently with Eclipse and source control. Thanks for your advice guys, I really appreciate it.

RE: Creating an Audit Trail
If you're using anything like the ColdSpring framework then you can apply this stuff using AOP. I've only recently started working with this concept but it really is a fantastic one. Failing that then I would defiantly recommend building a LoggingService CFC which handles all the logging for the application, it allows you to keep the logging methods consistent across the application. The logging class I've been working on is based on the concept of being able to log to both file and database, with different log levels, such as info, warning, error, critical, debug etc. Without knowing a little about how your current solution is built its hard to advise really, how does the current one work?

RE: cfqueryparam and dynamically-created SQL
Yep, I think like with queryparam, you have to look outside of the performance benefits when working with stored procedures. The other benefits come when you have very complex queries that are accessed from several locations within an application, or multiple applications, this means not having to duplicate the query SQL code, it also helps with maintenance of the query down the line if needs be. There are probably performance benefits, but I'd imagine that if performance is a REAL concern to you, there are plenty of other places within your application where your time would be better spent optimizing, you'll likely get better performance benefits by considering things like caching of queries and objects and so on. Like the other guys have picked up on, the biggest performance on queries will come from good SQL code, you're best off spending some time in your database studio checking query performance times and looking at execution plans, playing with the SQL and table Indexing.

RE: cfqueryparam and dynamically-created SQL
Try not to think about queryparam as a performance benefit so much, The performance increase isn't really anything that massive, think about it from a security perspective. Without cfqueryparam people will add, edit and remove content from your database, gain access to secure sections of your site, steal important information from you, names, address, credit card information and so on. queryparam really is important... _really_ important ... I can't stress that enough. Why is it that you find it annoying? Because of the extra few moments it takes to code? It really is worth that extra few seconds to wrap up all your dynamic parameters, once you get in to the habbit you won't even think twice about it. Rob -Original Message- From: Ben Mueller [mailto:[EMAIL PROTECTED] Sent: 24 October 2007 17:33 To: CF-Talk Subject: Re: cfqueryparam and dynamically-created SQL Thanks, all, for your replies. So, a follow-up question: will SQL create multiple prepared statements for each condition? If so, that's great. My fear is that it will only create 1 prepared statement for each cfquery block, so if the current statement doesn't match the previous statement, it would discard the previous one and create a new one. I have a bunch of queries that have 8 or more cfif conditions, almost all in the WHERE clause. Obviously, the more cfif conditions there are, the greater the likelihood that any one individual call won't match the previous one. I know cfqp is really good and all that, but this would be pretty annoying if I got no real performance benefit. Yes, to the extent that you are less likely to have another query with the same prepared statement (and the same execution plan, of course) that can be run again. Frankly, though, I wouldn't worry too much about that, since coding around that causes all kinds of problems.

RE: DEATH to HOMESITE
This is very true Brian, I agree whole heartedly, However, in the past I've always found subversion a total pain in the arse to setup and configure, it's just very confusing. My guess is that this stems from the fact that it was seemingly developed with Linux in mind, with command lines and compiling binaries, if they made it a little more intuitive to people (I suspect a large number of new developers will opt for windows OS as its 'what they know'), instead of the linuxy style methods they've used, I'm sure it would be more widely adopted by less experienced developers. It reminds me of the same reason why so many people pick up the bad habit of developing using access databases, it's simply because to a beginner developer they seem more accessible than a proper DBMS, As a novice developer trying to figure out installation and configuration of MySQL or SQL Server is quite confusing, especially when you have to setup management studio or phpMyAdmin, whereas the concept of a single file which can be easily created in a nice desktop based GUI is very simple to grasp, so most novice developers will start with access, especially considering all that functionality comes 'out of the box' with m$ office. I completely agree that source control through a proper SVN approach will pay dividends, but it's just one of those concepts that isn't A) Publicised to people properly, if you mention subversion to most amateur developers they would stare blankly back at you, however, ftp is very familiar. And. B) Accessible and simple enough to implement, even with these 'one touch' style solutions that subversion released for windows users. They're just my thoughts, Another quick gripe is with some of the guides and support documents I've read in the past, they're always typical Linux user style blog posts and forum remarks, showing a total lack of sympathy toward new and learning developers, making wide sweeping statements like 'and then simply update your system environment variables, and you're done!'... amateur users won't have a clue what you're on about, even someone whom is reasonably experienced with Linux development finds that stuff confusing.

Hello Guys, Is there any way to predict the database field length I'll need to facilitate my encrypted data? I'm using AES encryption with HEX encoding for all kinds for different data, from names and address', through to credit card information. I'm looking to define appropriate column lengths in my tables, is this easy to predict? Does AES encryption give me a regular string length regardless of that of the original string?

RE: Check File For Change
Thanks Claude, That certainly sounds like an excellent idea, I also like the concept about ensuring two files are not the same, just with different file names, this could most certainly play nicely in my application. Even if the tag is not published I'd love to hear a little about the concepts of how it works, you can mail me off list if you'd prefer to keep it private. Thanks again for the advice mate, I'll look into that directory tag too.

Check File For Change
Hello Guys, I've got an application that receives files from an upload form, the user can then come and view/download those files again at a later date. When the file is uploaded I store the basic details, such as the files path and name into a database table, these entries are displayed to the user with a download link, once the link is clicked the file is then served to the client using the cfcontent tag. Now, I'm looking for a method to ensure that the file has not been modified on the file system since the user uploaded it, the chances of it being modified are exceptionally slim, I know, but the consequences of it having happened are quite serious, so I need to be sure. I'm thinking about implementing some form of MD5 check sum on the files, this sum will be saved to the database when the file is uploaded, and checked against a newly generated checksum before the file is served back to the user again. Does that sounds like a fair concept? How severally is it likely to hit performance? Is there a better option? I've also not done any of this MD5 work before, has anyone got any pointers on the best way to handle it?

RE: CFC Composition and/or Extention
Brian or anyone else, I've come to a bit of a stumbling block when working on this extended DAO model which has gotten me a little confused. It comes when trying to figure out my create() method inside my sub class DAO. The idea we talked about below would be to pass in the object which is to be persisted into the create() method of my sub class object, and then at the top of the method run SUPER.create(ARGUMENTS.SubObject) before running my standard create query. Now the problem with this arises in the fact when I create an entry in my sub classes table, I need to know the ID of the freshly made entry in my super classes table, so as to establish their relationship. Now I could do this in my super classes create() method, by having it return the ID for the entry it just created, however this does feel a little unusual, mainly because I'm not used to working with super objects, is that the correct way to handle it or is there a better way which I can't see? Thanks again chaps, R -Original Message- From: Robert Rawlins - Think Blue [mailto:[EMAIL PROTECTED] Sent: 09 October 2007 21:50 To: CF-Talk Subject: RE: CFC Composition and/or Extention Oooh!

I now knight thee, Brian The Brain Kotek Thanks mate, Rob -Original Message- From: Brian Kotek [mailto:[EMAIL PROTECTED] Sent: 09 October 2007 18:25 To: CF-Talk Subject: Re: CFC Composition and/or Extention I would follow the same subtype/supertype idiom in your DAO objects. Have an abstract MediaDAO which handles all the database interaction for the Media table, and have concrete subtypes for each type of Media (VideoDAO, ImageDAO, etc.) so that they can handle their own type-specific data. I would have the concrete DAOs first run something like super.insert(data) so that the superclass will handle whatever has to happen with the Media table, and then they can go on doing their own type-specific database interactions with their own tables. On 10/9/07, Robert Rawlins - Think Blue [EMAIL PROTECTED] wrote: Thanks again Brian, another great reply, Yes these will defiantly be staying as a cast type, i.e. a image will always be an image and nothing more so at the moment I think the extended super class kind of makes good sense for me, taking a base Media object with the common attributes and extending it to the other sub classes which contain individual/unique properties. I then keep control over the whole lot with a service. One other thing I am wondering is how to organise my DAO's for this, should the Media class have its own DAO separate from the sub types? Or should the DAO's for my sub types deal with the media table as well as their own? I'm guessing the former, so that in my service saveImage() method it passes the super inited Image object to both the MediaDAO and the ImageDAO and they can just suck out the properties they need to persist it. Does that sound like the best option?

CFC Composition and/or Extention
Hey Guys, I hope you're all well, I've got a challenge when it come to composition which I was hoping you could give me a few pointers on, Basically I have a scenario in my application which has a supertype/subtype relationship between a bunch of tables and I'm struggling with how to build this kind of relationship between my objects. I'm not sure if you've worked with the supertype idea before, or heard the term, Its actually quite simple from a database point of view. I'll help clarify it with an example. In my application I deal with lots of different types of multimedia, such as Images, Text Files, Audio, Video, Games and a myriad of other things, however my application needs to be able to access these different media types from a single location in the database. So I have a single table called 'Media' which contains all the common details between different media files, like ID, Name, Size, DateCreated and such like, and then I have a myriad of different tables, like Text, Image, Audio, Video which contain all the unique information for each different type of message, along with a FK which links them back to my 'Media' table. Now what I need to be able to do is create a Media object within my application, but also have access to that additional information for when I write it to the database, and likewise when reading out. I'm not sure whether this is best solved with some form of composition, or perhaps this is where the 'Extend' attribute will come in handy for me? Create the media object as the Base class and have my other media types Extend it? I really don't know. What do you think chaps? I hope I haven't confused you too much with my babbling question.

RE: CFC Composition and/or Extention
Thanks again Brian, another great reply, Yes these will defiantly be staying as a cast type, i.e. a image will always be an image and nothing more so at the moment I think the extended super class kind of makes good sense for me, taking a base Media object with the common attributes and extending it to the other sub classes which contain individual/unique properties. I then keep control over the whole lot with a service. One other thing I am wondering is how to organise my DAO's for this, should the Media class have its own DAO separate from the sub types? Or should the DAO's for my sub types deal with the media table as well as their own? I'm guessing the former, so that in my service saveImage() method it passes the super inited Image object to both the MediaDAO and the ImageDAO and they can just suck out the properties they need to persist it. Does that sound like the best option? Thanks again mate, Rob -Original Message- From: Brian Kotek [mailto:[EMAIL PROTECTED] Sent: 09 October 2007 16:30 To: CF-Talk Subject: Re: CFC Composition and/or Extention It depends on what you need to do, and how you envision media changing over time. You can definitely create an abstract Media component that is extended by concrete components like Image, Video, etc. The only limitation is really that a component can only inherit from one superclass. Which means you can't have a media item that is treated as two kinds of media (ie Video is a video file, and also an Image File (when treated as a bunch of individual images)). The advantage of composition is that a component can have multiple objects associated with it, and that those objects can be dynamically added or removed at runtime. So you gain flexibility with composition, but you add complexity as well. The advantage of inheritance is that any external code can treat all subclasses of Media as simply the abstract type Media (this is polymorphism). So, if you are pretty sure these things are truly a one-to-one IS-A relationship (and I think they seem to be, but not knowing more about what you actually need to do going forward it's impossible to say for sure), and you want external code to be able to treat all types of media in a similar way, using the same API, then inheritance sounds like it will work just fine.

Have an abstract MediaDAO which handles all the database interaction for the Media table, and have concrete subtypes for each type of Media (VideoDAO, ImageDAO, etc.) so that they can handle their own type-specific data. I would have the concrete DAOs first run something like super.insert(data) so that the superclass will handle whatever has to happen with the Media table, and then they can go on doing their own type-specific database interactions with their own tables.

AOP in ColdSpring and ModelGlue
Hello Chaps, I've been working with both CS and MG for a while now and we're getting on famously together, It took me a while to feel comfortable with relinquishing that control over to the frameworks, but once done I can genuinely feel the development benefits, it's quite amazing. This past weekend I've made my first ventures into studying the benefits of the AOP concepts which are available to me in CS, and they have gotten me quite excited to say the least, however trying to find some good working examples of how to apply them within a MG/CS application is becoming quite tricky and I'm struggling to figure this stuff out, so thought I'd come looking for a little help. For the sake of argument and example, let's take a simple task like validating some data which is being passed to a service object. I'll give some basic mocked examples of my controller and advice object that I have at the moment. Controller: cffunction name=registerUser access=public output=false returntype=any cfarguments name=Event type=any required=true hint=I'm the event / !--- Create New User --- cfset var NewUser = VARIABLES.Instance.UserService.create(ARGUMENTS.Event.getValue(name)) / cfreturn ARGUMENTS.Event / /cffunction Now obviously that's very stripped down version of my controller method, but for the sake of argument let keep it as simple as possible. Now, I need to validate that 'name' variable to ensure that it doesn't have any numbers in it, if it does then I want to throw the user back to the form page with an error message. Take a look at my basic advice object below: Advice Object: !--- Advice Method --- cffunction name=invokeMethod access=public returntype=any hint=I supply the advice to the method call cfargument name=methodInvocation type=coldspring.aop.MethodInvocation required=false / !--- Create Temporary Local Structure --- cfset var LOCAL = structNew() / !--- Validate Data --- cfif refind([0-9], arguments.methodInvocation.getArguments().Name) !--- Data Not Valid --- cfelse !--- Data Valid --- /cfif !--- Return Out --- cfreturn / /cffunction Now this is where I become a little confused, see, in the old days I would validate the data inside my controller, and if the data failed validation I would add a result of 'failed' and update the viewstate with an error message, then use the events xml definition to pass the user back to the form if the result of 'failed' was present. However, from what I can see here I have no access to the event object from my advice object, so I'm not able to add results or update the view state, All I can do is simply return a value, is that correct? How do I use the advice object to control the user back to the form with an error message? I'm feeling a little confused about it. Thanks for any 'advice' guys, I really appreciate your time.

RE: Graphing date ranges...
Hey pal, If you're looking to fill in the holes where there is no data for a particular date the best way to do this is with a Calendar table in your database, you can then select the desired date range from this and LEFT OUTTER JOIN it to your table with your statistics data, that way It'll return a row for every date in the range, regardless of whether you have data for that date or not, so you get no gaps. It's more of a SQL type thing so you might be better off asking there, and looking around for some help building and populating a Calendar table, it's not an overly complicated task, but a calendar table will really help you out for this and many other tasks too, I'd highly recommend one.
