On Monday 29 January 2001 10:19, Fred Yankowski wrote: I missed the original message, but I'm trying to do something similar -- use Python Methods rather than DTML -- and I found one critical difference just today. Here's an example: I've got an SQL Method called 'select_item' that takes 'item_id' as its only input parameter. I've got a DTML Method 'form_action' that has 'item_id' in its namespace by virtue of being posted from an HTTP form. When I would invoke the SQL method from DTML I could do just dtml-call select_item and the SQL method would get the item_id from the DTML method. But when using a new 'action_script' Python Method (PythonMethod 0.1.7) I have to pass that item_id explicitly from the DTML dtml-call "action_script(item_id)" and action_script itself has to call the SQL method like so self.select_item(item_id=item_id) I don't know why the explicit parameter passing is needed in the latter case (DTML to Python Method to SQL Method) but not in the former (DTML to SQL Method). I'm sure I'm missing some trick. In fact, this aspect of Zope -- when values are passed explicitly and when not -- is a major confusion for me. (And anyone who responds about "Zen" deserves to have the size 12 boot applied.) The way it appears to work is this: DTML will pass it's namespace on implicitly. Python will not. The exact details of what are passed are somewhat of a mystery, true. Rember, of course that dtml-var "method_name()" is a Python expression. As I understand it, the equivalent of: dtml-var method_name as a Python expression is: dtml-var "method_name(_.None, _)" When it comes to Python scripts, yes, you must pass all parameters explicitly. IMHO, this is a good thing in many cases, as it forces you to make sure you are passing the correct values. But I can see how implied values could make life easier... oh well... Have a better one, Curtis Maloney P.S. I'm now moving my application to Zope 2.3 in the vague hope that PythonScripts will handle this problem better. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] Did I miss some major change in Z SQL Methods ?
Green things,
I have a few methods poking about that just don't seem to make sense
A Z SQL Method ( Returner.sql.getDetails ) which simply contains:
SELECT * FROM Returner WHERE ReturnerID=dtml-sqlvar User type="int"
Which returns everything as expected. The I have a Python Method which
refers to it, simply wrapping it up, and taking the first (of what should be
only one anyway) element. It contains the following:
( Returner.getDetails(self, User) )
return self.sql.getDetails(User=User)[0]
Now.. for some reason, the following throws complaints about not being able
to find ANY of the fields in the row:
dtml-with "Returner.getDetails(Returner, User=12)"
dtml-var fieldName
/dtml-with
Now, previously I've accessed my ZSQL Methods directly from DTML, but this
time I was trying to abstract slightly, for various reasons... But this
bizarre behaviour has begun. Can anyone explain what I'm missing?
Zope 2.2.5
ZMySQLDA 1.2.0
PythonMethods 0.1.7
Linux (RH 6.1 +)

[Zope] Adding users with a PythonMethod
Greetings, I'm trying to add a users from within a PythonMethod. I have searched this list and found examples of how to add via DTML, but they all seem to require REQUEST. I have built a dictionary containing the appropriate keys, and passed that as REQUEST, and the following error occurs: Error Type: KeyError Error Value: SCRIPT_NAME From what I can see of the sources, if you pass a non-None REQUEST to _addUser (via manage_users) it will return manage_main. This seems odd to me, because I can't see how you could pass the user details otherwise. So, what I'm left to conclude is it's easier to add a new user from DTML than it is from a PythonMethod.

it was the simplest solution when you needed TTW editing.
It would take just a little nudge (the sequence-* to sequence_* patch, and
perhaps this dtml-break) to make DTML much easier to use. I consider DTML as
a relatively unthreatening step for people between newbie status and moving

queries to MySQL for data from the tables in the DB, instead of the

Also when i submit a query
to add data to a table zope returns what appears to be a error message in
my browser, which the zope control panel is using, but the data is still
added to my DB table. When submitting a query to extract data, if my python

an error in your SQL syntax near ' '', '', '', 2000 )' at line 3
My first recommendation would be to grab yourself a good book on SQL.
O'Reilly Assoc "MySQL mSQL" is a good reference in your case. The
problem with your select statement is it is incorrect. It should be in the
form:
SELECT field list FROM table
WHERE fieldcomparisonvalue
[AND|OR] fieldcomparisonvalue
...
so, in your particular case, I would guess:
SELECT * FROM songdetails
WHERE fifthFieldName = 2000
---
- SQL used:
SELECT * FROM songdetails
WHERE(
'',
'',
'',
'',
2000
)
I'd be most grateful if you could provide some answers to any of these
probelms as soon as you can. Even if you don't know if you could point me

Re: [Zope] Calling other frames (OT)
On Monday 15 January 2001 22:51, Oliver Bleutgen wrote:
I think probably Javascript is the 'cleanest' solution in this case,

to make every link target the topmost frome (e.g., target="_top") and

that all frames reflect the latest situation, but it can be annoying
to see the whole browser redraw every time you do anything. However,
if your browser doesn't *do* Javascript (so long as it does do
frames hmm.. how likely is that?) then it would at least work
There' s always the possibility that people disable javascript -
and checking for instance http://www.guninski.com/browsers.html
I would say they have reason to do so.
Agreed. I run NS4.76 with JavaScript disabled... it's the only way I've
found to stop it pissing away my memory.
My take is that one should at least provide a non-javascript alternative
to browse the site. This also helps with search-engines
IMHO, JavaScript should be used to provide faster access to the same
interface, but never to add functionality that is not otherwise available. A
great example is http://www.asus.com.tw ... they have a side-bar menu
which, with JS, will give you sub-menus when you hover over the links, etc.
However, if you just click on the link, you are taken to a sub page which has
the very same sub-menu, and this happens regardless of JS.
cheers,
oliver
As for this frame problem... seems like you're voiding the best (IMHO) use of
frames, which is to prevent reloading of portions of the page. Otherwise I
just render all the objects into elements of an 'uber-table'...

You have to put "SELECTED" on the 'option' tag you want to be default.
This means iterating over your list with something like:
dtml-in CountryList
option dtml-if "_['sequence-item']==custcountry" SELECTED/dtml-if
value="dtml-var sequence-item"dtml-var sequence-item
/dtml-in
If you don't already have the country list in an object somewhere, I
recommend adding a "lines" type property to either that object, or an
appropriate folder, and put them in there.
And remember... if "custcountry" doesn't exist.. this will break... do
putting a:
dtml-unless custcountry
dtml-call "REQUEST.set('custcountry',' ')"
/dtml-unless
at the top of the page won't hurt.

As I have said several times on this list, this is well overdue. Hopefuly
the '-' tags can migrate their way out of Zope the way !--# has.
The second problem is if you put one in-tag into another.
You have to use dtml-let oder REQUEST.set() with variables
of the outher in-tag to be able to reference them in the inner
loop. The code becomes very ugly this way. So my idea was to
give the in-tag an optional argument, called "prefix" to
prefix all the sequence-variables with a custom identifier.
So you can write:
dtml-in some_sequence prefix="outer_"
dtml-in some_other_sequence
dtml-var outer_sequence_item:dtml-var sequence_item
/dtml-in the inner sequence
/dtml-in the outer sequence

elicit the same old newbie questions to this list.

[Zope] Tag attributes...
Green things, I've written a handy tag for my Zope site, and it accepts a few attributes. This is all going well, and the tag is working nicely. (Even though I couldn't seem to find any docs on doing this, I just fumbled about with the source from the sendmail tag) However, it seems there is no way to determine if an attribute is a quoted string, or just a variable name, and the only solution is to provide different attributes depending on how this information is passed. Have I missed something, or is there some hidden feature of 'parse_params' that I'm missing?

Re: [Zope] [Urgent] Zope good for multiprocessor hardware
On Thursday 23 November 2000 18:46, Daniel Dittmar wrote: I don't think Python (and therefor Zope) will profit from a multiprocessor as there is something known as the 'global lock' which prevents more than one Python thread to run at a time. Things look different if you're accessing a database (other than ZODB) because a properly written database module will release the lock while waiting for a reply. So Zope would use one processor and the database the other one(s). Other possibilities: - you have lots of static data, then these could be served by Apache directly (which would benefit from the additional processor) - you have some very expensive operations (generating GIFs from data etc.). Then you could implement those in a separate server. I would have to agree with this. We are currently running Zope on a dual processor Sparc station. However, also on that box is MySQL, and Apache. So, whilst Zope can only use one CPU, there is still plenty of CPU time for the DB and Apache to handle their requests. I've not done any tests, but I can't see how this _wouldn't_ be faster than a single CPU. And, of course, if you happen to be running Linux 2.4 on your system, the multi-threaded IP stack will definitely benefit from the extra CPUs.

Re: [Zope] Form variables with same name as folder names
On Tue, 14 Nov 2000, "Burwell, Becky wrote:
Hi. I am new to using Zope and just got stuck on the following problem. I
am trying to use forms with an SQL database.
I have a form with checkboxes and I use variables like FOO to capture the
value. For example: input type="checkbox" name="FOO" value="1"
The form has a post with the action to call a DTML document. In my DTML
document I call a Z SQL Method called InsertMethod with REQUEST as the
argument, for example InsertMethod(REQUEST).
My Z SQL Method InsertMethod has arguments including
FOO=""
And then in the body of the Z SQL method I have:
dtml-if FOO
{code to insert into a database table}
This working UNTIL I created a Folder named FOO. Then the value of FOO in
the Z SQL method seemed to be the FOO folder and not FOO from REQUEST. My
workaround was to call the variable FOOCHECKBOX.
2) is there some way I could have referred to the variable FOO in my Z SQL
method without resorting to renaming the variable in my form?
A sneaky problem indeed, and once again, one caused by "convenient"
shortcuts. (o8
The simple answer: use REQUEST.form['FOO'] to refer to the form variable.
The longer answer:
To make life simpler on our key-weary fingers, DC made all the form variables
part of the namespace, but put then sufficiently down the search path so they
wouldn't get in the way of other objects. Most of the time this is just
great, but occasionaly you do run into this problem.
So, you can explicitly access all form variables with REQUEST.form[]... just
as you can access all cookies via REQUEST.cookies[]
I would advise you make a small DTML Document containing dtml-var REQUEST
just to have a look at what it contains THEN go and check up the ZQR for
all the members of REQUEST... and RESPONSE, while you're at it.. (o8

Hi Andy, actually, if you are talking about permissions, this setting gives
anyone in the world read write and execution access to your

Greg,
Having all your dtml, html, py, pyc, doc and other files executable just
doesn't make sense! In fact, if you make everything 440 except for in /var,
where you make it 640, and owned by a "zope" user, this is the safest.
Of course, it DOES mean you have to explicitly chmod any file you want to
edit...so if you're not THAT paranoid, you could use 640 everywhere...
If you put all the files in a zope group, then you can set the permissions
660, so only people in the Zope group can edit the files.

Yes, my mistake. I did mean 'browser safe'. I was aware of the previous
belief of 216 (mostly because of 256 colour modes less 40 system colours),
but as I stated, a recent study has "dispelled the myth", claiming (and now I
correct myself :) only 22 browser safe colours.
http://slashdot.org/articles/00/09/08/1622204.shtml has some more details,
and a link to the actual article.
The only other possible reason I can recall is that some of the 'named'
colours are not supported by all browsers, or are not interpreted the

No, the problem is, that they are not displayed the same.
Not long after posting my message I realised this also. (o8

(o8 While I am going through the documentation, which will be of help no doubt, I hope these initial questions attract some replies. Here are some of my starting requirements; 1) I need to create a small DB retrieval(mainly) system with only 000's of records and possibly 00's of users. Zope has interfaces for many popular DBs, and a very easy way to use them. If you check http://www.zope.org/Products you will see adapters for DBs like Oracle, Postgressl, MySQL, Sybase, and many others. By using SQL Methods (Documentation at http://www.zope.org/Documentation/Guides/ZSQL-HTML/ZSQL.html ) you can easily insert and extract from any connected DB. As for your user base, I would advise you try one of the alternative user management tools ( http://www.zope.org/Products/user_management ) 2) Only a few nominated users will have update rights to the data. Zope makes it easy to use fine grained access control to documents for various 'roles', which you can create and name yourself. Just attribute each user with the appropriate 'roles', and they have all and only the access you give them. 3) The user needs to be able to search for all occurrences of any of the data items presented to them I'm not entirely sure what sort of 'data items' you have in mind here, but afaik, ZCatalogs are a very powerful search tool provided as standard with Zope. http://www.zope.org/Documentation/How-To/ZCatalogTutorial 4) It seems the users have a UNIX infrastructure with an existing DB that is ODBC compliant and has data items which I need to retrieve and update. There is at least one, possibly two Unix based ODBC interfaces for zope. ZmxODBC being one of them. 5) Re: this last point, I'm not sure of yet if my app also needs to be hosted by the UNIX server or whether it can have it's own server and simply make ODBC calls to the UNIX box. I also don't know what would be preferable. I guess having it all on the same box is more efficient. Well, Zope can run anywhere you can run Python. I personally have run Zope on Solaris (Sparc), Linux (i386) and MS Windows 98. 6) I am based in Australia and if anyone is in the same timezone (ie. Melbourne) it would be great to make personal contact. I live in Melbourne. I hope someone out there can point me in the right direction. Always willing to help another Zopista.

Session data is retained between visits (a side effect, but a welcome one), so I really cannot be sure of how many sessions were used. All key-based session management systems are intrinsically unsafe, since other people can tap into your session, with non-zero probability, if the key-length is finite. The only hope is to make the key long enough, so even if the hacker has a supercomputer, it would still take him/her the age of the universe to crack into your website. One thing I mentioned to Pavlos (and/or Anthony Baxter?) before is that the key lengths of their cookies are a bit too short. For my HappySession product (another session management product, which is RAM based), I cranked up the key length to 128 alphanumeric char key, exactly because I wanted no key collision for a long long time. :) Well, yes and no. This really depends on the sensitivity of your data, and how likely it is for someone to try to crack your site.

ProxyForward means that when a URL matches a rule, it will be 'forwarded' to another server, and the returned page issued as if from Apache. From the benchmarks I've seen, this is the fastest way to run Zope. However, I can see how it could confuse Zope into thinking two different users requests are from the same machine, since all the requests are coming from Apache. However, I am hoping (going to check on this, of course :) that the smart folks at Apache have made it 'proxy' properly, to avoid this sort of problem.

Not quite. To attach a file, you must make your message a "multi part MIME"

Why don't you write a shell script which
1. starts the ./stop script, and
2. starts the ./start script
every 5 minutes? So you don't have to check if Zope runs. It's like a
restart.
That would be very intensive on the server. Imagine if your office file
server was set to reboot every 5 minutes, "just in case". It's far
better to just check if it's dead and only then restart it.
Sounds to me like you need a script to do the following:
check if /tmp/zope.pid exists
if it does, check if a process of the number stored in there is running
if not, start zope
if not, start zope.
I really suck at shell scripts, but from what I've seen, you will need some
way to grab the PID of Zope as it starts.

We did include some JavaScript to make the focus change when ENTER is hit,

Just a number, or are there other possibilities? What is on the card is, strangely enough, what is on the card. Magstripe readers commonly interface to ps/2 keyboard ports via a 'chok' or 'wedge', which just plugs inline with your regular keyboard. Thanks. Not a problem.

My guess (untested) is :

dtml-in getUserNames
option value="dtml-var sequence-item"dtml-var sequence-item
/dtml-in
/select
To slightly generalize, how would one tree-walk to find the list

Well, as I said, this is untested, but I'm assuming getUserNames does this
for you. The ZQR is somewhat sparse on the details.

First of all Zope is a product of a north american company but is used
worldwide. Not all countries use the american form of dates, so it would
be nice to have a standardized one (in my opinion this applies also to the
standard date functions in Zope).
The reasons for establishing ISO 8601 apply here as well:
- ordering of month and day are different in Europe and America,
this leads to difficulties interpreting date values
- ISO dates are sortable by string functions
- ISO dates are easy to parse by humans AND programs
Opinions?
I agree. If everyone standardised on ISO 8601 in written date and time
formats, the world would be a saner place. Writing MM-DD-YY(YY) is just
silly in my opinion, no matter how you like to say it out loud. It may have
been acceptable in times past (like when the Internet was not nearly
globally ubiquitous), but these days it's just an anachronism (as is
DD-MM-YY, because it is easily mistaken for MM-DD-YY). Likewise for 12 hour

hi Curtis
Yaaay! It works :) Thanks a lot!
I wouldn't have found "objectValues" on my own .. where'd
you learn about that? I'm ploughing through docs and wiki's
now, just don't know if they're the right ones. I also need
to read more about Python ..
The Zope Quick Reference. An indispensible resource, which you can find
through the zope.com Documentation section.
Anyway, I messed about with your instructions a bit, and
tried:
dtml-var "text_content('member')"
(which renders nothing), and:
dtml-var "text_content"
which renders:
Python Method object at 13bead8
Dunno how soon I'd've navigated that maze on my own. The
"text_content" I can understand -- putting it between ""
means that it should be evaluated, so text_content is
evaluated without parameters, and dtml-var is being asked
to render the method itself. Doing "text_content('member')",
text_content is replaced by the result of evaluating it
on 'member' .. this works when it's fed the output of
getElementsByTagName, but since I'm already "in" the members,
there aren't any member elements to be had inside them --
only their text_contents.
Another option is getChildNodes()
Well, that's as far as I can puzzle it out ..
Now for another question (which I'm throwing to the group
seperately too):
How do I show all groups that a specific member is part
of? In other words, if I have:
teams
team
nameHam/name
descWhite papers, brochures, case studies./desc
memberEduan/member
memberJacqui/member
/team
team
nameGreen eggs/name
descGreen papers, brochures, case studies./desc
memberTracey/member
memberJacqui/member
/team
/teams
how do I get
"Jacqui is member of the Ham and Green eggs teams."
yuck
dtml-var member_name is member of
dtml-in "objectValues('team')"
dtml-in "objectValues('member')"
dtml-if "text_content() == member_name"dtml-var name, /dtml-if
/dtml-in
/dtml-in
that's my best guess, but you _might_ run into a problem with 'name'

[Zope] ODBC SQL DA
Greetings,
I have been digging about for a couple of weeks, and either I'm missing
something (most likely :) or where there once was a mxODBC adapter, there is
no longer?
I am going to need to dig into an ODBC based DB (DataFlex), for which we
have an ODBC interface. The db was not my choice, so there's no option there.
However, I saw a few references to various ODBC DAs in the product lists.
With ODBC supposedly being a 'generic' interface, why does each different DB
require a different DA? Is this just tailoring the DA for that specific DB?
In which case, would it be possible to build a "Generic" ODBC DA?
Fortunately, this is not a priority project, but I would appreciate some
details in this matter.
Oh well, back to the archives.
Have a better one,
Curtis Maloney

If this isn't a problem, then your solution is great. I don't understand why you think it doesn't. DNS has clearly demonstrated the ability to handle 'thousands', and the entire scalability of a cluster is the addition of machines. You appear to be desirous of having a machine handle a section. Thus, for thousands of sections, you have thousands of machines. Again, with a ZEO clusters the bottleneck/SPOF would be the ZSS, but that _could_ be worked aorund, and has nothing to do with 'sections' of a website. Bill, Whilst the structures you've described are very effective, your example of libc.org required one thing in particular that I'm not sure is available: prior knowledge of which sections will be hit hardest. Essentially, your setup allows any 'server' to become a 'server cluster' for scaling purposes. Great! So, if for now on we assume 'server' can mean 'single or cluster of servers' The desire isn't for fixed server-section relationship. Instead, a 'preference' for that section to go to a particular server, so that the request 'hopefully' goes the server with the greatest chance of having the relevant objects in cache. In fact, with the further information provided, what you really want is for requests from a particular client to go to the same server. This would be better served with a redirection to a server specific domain name (serverN.mysite.com). However, for the initial request, your best choice is to go to the server that last served those pages. Since dynamically tracking this info would be onerous, by encouraging requests for one section toward a particular server, you improve the chances of it holding the relevant objects in cache, with merely a fraction of the processing/data overheads. Beyond that, your bottleneck would be networking. Whether yoour individual BE servers responded directly to the web browser, or whether they were channeled through a single/multiple FrontEnd servers.

The way I would do this is have section1.contrived-example.com section2.contrived-example.com section3.contrived-example.com with siteAccess, and then each zope would serve it according to it's IP (though each "could" serve each site). Then you can use whatever IP/DNS load balancing tool your heart desires. I think most people seem to be missing the point here. The idea is that ALL servers can serve ALL content. HOWEVER, the 'load balancer' will opt for a certain server for a certain URL, in order to improve cache hits. So, for www.contrived-example.com/dir1 it will first try server1, but if it's busy (or down) it will try others. This way, the cache on server1 is more likely to contain objects relevant to /dir1 and thus have a higher hit rate, therefore improving performance. An enforced 'mapping', as you were suggesting, removes ALL redundancy from the site, but would likely provide even better cache hits. a thought, Have a better one, Curtis ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

I think you've completely missed the point of my post.
Firstly: I don't use those meta tags unless i absolutely have to. The
redirection I have in place works fine, when it gets parsed.
Secondly: My problem is NOT redirecting the page.
I added the redirect as a debuging tool, to find out if the DTML parser was
getting that far. In case you've not noticed, any time you get an error,
that object is not rendered at all, instead the error report is put in its
place.
What it showed me was that the page in question was not being parsed at all,
even tho the traceback shows it is.

[Zope] Bizarre error with standard_html_header
Ok...
i dtml-commented out standard_html_header, and it worked fine..
What gets me is the header should work fine. If I understand Acquisition
properly, the object should be rendered from within the namespace of the
directory it's being called in.
So, if i get "/internal/register", and register exists in / not /internal,
then it will be rendered as if it was in /internal.
Fine. In that case, the standard_html_header in /internal, which requires
the existance of various objects in /internal, should render fine.
What confuses me is the "TypeError: too many arguments; expected 2, got 3".
How can this be happening?
What am I missing, here?

Then, for each iteration, I handle the data however...
I wind up with:
dtml-in "_['sequence-item'][2]"

But that's where the problem begins.
Insted of :
dtml-in x mapping
you have to use:
dtml-in "[x]" mapping as a list
dtml-in "(x,)" mapping as a tuple
So, you're saying that by creating a list with one element which is a
dictionary... ?

Absolutely. Apache is many times faster than Zope. (Don't know much

Not true. I have been programming using PHP and PERL, and together with
Apache(DSO) they are quite fast. They do offer sessions tracking,
authentication, database API + other features. It's just that due to the
increasing 'hype':) on Zope and the vast array of features that it seems to
offer, i'm sort of "attracted" by it:)
ahem As I said, compared with Apache, for static content, it is slow.
However, just like with CGI, PHP, and various other technologies, ZOPE can
work through Apache.

does not allow you to do anything you can't already do, but it makes those
things SO much easier. (o8
Of course if i have time, i will play ard with it and see how good it is.
Problem is that time is not really on my side and i need to decide on my
next development tool fast(i have yet to try out other stuff e.g. ASP, JSP,
Servlet..) I heard that the learning curve for Zope is quite steep, plus
the documentation is not(?) that comprehensive, compared to e.g. PHP. What
are your comments though? i may be wrong here...
Well, I find that Zope allows a MUCH quicker development cycle, along with
various other advantages, such as remote edit of pages from any browser on
the net.
Yes, the documentation is lacking. However, IMHO, a competent programmer
(especially one with a decent grasp of OO) will pick it up quickly with just
a couple of reference documents. (The Zope Quick Reference comes to mind :)
A friend of mine was a hardcore PHP nut, before I introduced him to Zope, and
was amazed at how simple it made work. I think the thing that slowed his
learning of zope the most was often expecting solutions to problems to be
complex.

firestar
By all means, try it out. And when you're done, tell us what you think.
What you like, where you think other technologies win out, and why. Zope is
developing quickly, and the features are easy to add because of the open
nature of the project, and the whole product system.
