Re: Database Design - Multiple locations

Re: Database Design - Multiple locations
Why not model all the different location types with an abstract parent (like 'Location'), and then relate from your data object to the abstract 'Location' class? Something like this: Class/entity hierarchy: Location : City Location : State Location : Country Location : Region City could have a relationship 'parent' that relates to a State (concrete subclass of Location) or it could even have a relationship to 'Location' in case a city can be in a state (for the US) or a Region... etc. Hard to say since I don't know what your city table looks like. Since you have a single table for each location type, this would generate 6 queries when faulting the Location abstract entity, but at least it would be elegant. For the to-one relationships, you could include information in your primary key that would allow you to decide the table through delegate methods. If your data set is reasonably sized, most used objects and relationships would end up in memory anyway.

Re: WOFileUpload
I like the idea of this approach, but maybe I'm not understanding you
completely. If I change my html to not use WOFileUpload and instead just
upload like a normal file-upload:
Browse file:
input name=fileName type=file
brwebobject name=SubmitButton/
---
SubmitButton: WOSubmitButton {
action = submit;
value = Upload File;
}
Then it seems like I'm still reading in all the data before I even get to
my takeValuesFromRequest. In fact when I get to larger files (~ 500MB -
1.0GB) I don't even get to the takeValuesFromRequest and something else goes
wonky.
Is this how you meant to implement this? Or am I missing another
web-objecty way to grab the file name information.
Thanks,

Hi Sirius,
This approach does not solve reading _any_ data from the wire, but it will
cut the user short if a limit is exceeded; use WOMultipartIterator instead
of a WOFileUpload.
(In takeValuesFromRequest or inside of a direct action, )
first check the header and dump out if it is too big (although it does not
give much insight if you have multiple files):
request.headerForKey(content-length)
... and if the header is lying! That dirty rascal!!
grab the multipart iterator
WOMultipartIterator multipartIterator = request.multipartIterator();
Loop through the formdata calling multipartIterator.nextFormData()
WOMultipartIterator.WOFormData formData =
multipartIterator.nextFormData();
Test for a file input:
formData.isFileUpload()
If it is a file upload, grab the name and the stream
formData.name()
InputStream in = formData.formDataInputStream()
Now write the stream to disk manually, reading into a buffer and writing
to an output stream, keeping track of how many bytes you have written and
dumping out if you exceed the limit.
Something like this should work:
byte[] buff = new byte[25600];
int b_total = 0, b_read = in.read(buff);
OutputStream out = new FileOutputStream(/tmp/maybearealybigfile);
while(-1 != b_read)
{
b_total += b_read;
if(b_total MY_MAX_BYTES)
{
... close output stream and delete the partial file from disk ...
break;
}
out.write(buff, 0, b_read);
b_read = in.read(buff);
}
... close your streams if they are open ...

Access to D2wContext / RuleSystem while rendering
Hi all, I've made some D2W templates and components. On some of them, I want to access the rule system through the d2wcontext (asking for some color preferences and other values I have added in rules to the .d2wmodel file). When I have an action method in the page, I can use the d2wContext().valueForKey(color) to ask the rule system to look for the value of the color key. Until here, that works fine. However, when I do the same while rendering the page (or in the constructor), I can't access the current d2wcontext using the d2wcontext() method as it returns null. This makes me think, the d2wcontext isn't initialized yet at this point, but then, how am I supposed to get a reference to it? Or else, does someone know how can I ask the Rule System for a value in the rendering process? (using the appropriate task, entity, etc. values). I hope someone can help me.

I looked at our code using Digester (code which I was not at all involved in, my story, and I am sticking to it), we imported them into intermediate (non-EO) classes and then fetched / created EOs (as appropriate for update / create). We then copied the needed values from the intermediate classes. I think that was necessary as the XML represented EOs getting inserted into an existing, complex graph of objects.

The values themselves need to be changeable for each pool, but the size would be constant so it doesn't need to be mutable, Um, no. Mutable also means that the contents can change, not just the size. As the late, great Johnny Carson would say, I did not know that. since the number of rounds in a tournament is known and static, e.g. for the NCAA tournament the size would be 6, since there are 6 rounds. This is the only per round information that needs to be kept. I'd be tempted to make this into an EO with an order attribute, an point attribute, and relationship to Pool. That's what I ended up doing.

Re: WOFileUpload
Hi Sirius,
I use a a direct action. I began following this approach because I
am dealing with large files and had no desire for them to be in
memory. In the WOMultipartIterator docs it says: The InputStream
subclass is a WOFormDataInpuStream and can be used to stream large
file uploads to disk.
To test, create a multipart form with a file upload in an HTML file
and set the form action to a direct action on your webobjects app. I
can send you some sample code if you'd like.
:)

I like the idea of this approach, but maybe I'm not understanding
you completely. If I change my html to not use WOFileUpload and
instead just upload like a normal file-upload:
Browse file:
input name=fileName type=file
brwebobject name=SubmitButton/
---
SubmitButton: WOSubmitButton {
action = submit;
value = Upload File;
}
Then it seems like I'm still reading in all the data before I even
get to my takeValuesFromRequest. In fact when I get to larger files
(~ 500MB - 1.0GB) I don't even get to the takeValuesFromRequest and
something else goes wonky.
Is this how you meant to implement this? Or am I missing another
web-objecty way to grab the file name information.
Thanks,

WO 5.3.x amp workaround?
Hi all, Does anyone have a generic workaround for WO 5.3.x to prevent ampersands from getting escaped on R/R loop direct actionURLs? I have a page which is sometimes returned as a session-less based direct action and sometimes it's returned as a session based direct action with a wosid on the URL. In the latter case, the URL looks like this: MyWOApp.woa/wa/loginPage? wosid=V7HO3tAja0qE0HYoDyxZiwamp;errorMessage=Invalid+login+or+password Obviously, I'd like to change the amp to just . My current workaround is: String errorMessage1 = (String) this.context().request().formValueForKey(errorMessage); String errorMessage2 = (String) this.context().request().formValueForKey(amp;errorMessage); Thanks, Joe ___ Do not post admin requests to the list.
