[Zope] DTML difficulties
I'm working on my first zope product and, while everything has gone relatively smoothly so far, I'm having some issues. The product is a folderish object which contains 3 subfolders, each of which contains a specific type of object. The structure looks something like this: work/: Main folder, UI, etc jobs/: List of all jobs projects/: taskforces/: Each folder contains a job, project or taskforce object, as well as the UI to manage them. Projects and taskforces are simple objects with names, descriptions, etc. Logic will be attached to these classes so that, when instances are viewed, they will search for jobs which are assigned to them. Each job can be assigned to multiple projects/taskforces. Now, the difficulty. I'm working on the UI for the job add form, which is in work/jobs. The form needs to iterate over the contents of projects/ and taskforces/, and I can't figure out how. Here's what I've tried: tr th align="LEFT" valign="TOP"Taskforces/th td align="LEFT" valign="TOP" select multiple name="taskforces:list" dtml-in "PARENTS[1].taskforces" option value="dtml-var id"dtml-var title_or_id/option /dtml-in /select /td /tr tr th align="LEFT" valign="TOP"Projects/th td align="LEFT" valign="TOP" select multiple name="projects:list" dtml-in "PARENTS[1].projects" option value="dtml-var id"dtml-var title_or_id/option /dtml-in /select /td /tr And the error I get is: ||Error Type: TypeError | ||Error Value: unsliceable object| Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/App/special_dtml.py, line 120, in __call__ (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/DocumentTemplate/DT_In.py, line 672, in renderwob (Object: PARENTS[1].taskforces) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 617, in __getitem__ (Object: RoleManager) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 257, in _getOb (Object: RoleManager) TypeError: (see above) Can anyone offer any advice? ___ 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] Limited folderish objects
The Folder class offers quite a bit of the functionality which I need for a current project. However, what I'm attempting to create isn't a traditional folder for DTML objects, methods, etc. Instead, I'm creating a folder which contains subfolders which are intended for specific objects. The "available objects" list in the parent folder should only allow the creation of a certain type of object. So, how can I do this? I was told that I could modify the permissions on the folder to prevent other objects from being added, and this seems to be confirmed by what I managed to find out about filtered_meta_types, but I'm not sure. Can anyone offer any advice?

[Zope] Uploading files
I'm trying to write a replacement form which allows users to upload images into a folder. I'm almost there, but not quite. I'm having difficulties getting the file contents into the database. I have an input type="file" field, and I'm fairly sure that the data is being sent. When I create the Image however, I use file=REQUEST['file'], and the resulting image stores the path to the file, instead of the file contents. So, given that I've uploaded a file, and that its name is in REQUEST['file'], how do I get at its contents when creating the Image? ___ 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] Folder-specific metatypes?
I'm working on a product in Python which implements a folder, but restricts the metatypes of the objects which can be added. How, exactly, do I go about doing this? I've tried overriding the filtered_meta_types method, but I'm returning a list, and it seems that I should return a list of dictionaries instead, but I'm not entirely sure how the metatype is converted into a dictionary. I also noticed the _product_meta_types variable, but rgreps of the zope code didn't reveal anything about this variable. Am I on the right track with these?

[Zope] Z class complexities
I'm having a kinda complex problem, and hopefully my explanation can
do it justice. :)
I'm using zope to construct an XML document from the contents of a
folder. Basically, the folder's index.xml iterates through the
folder's contents, rendering each object to produce the final
document. The objects are separate z classes which combine various
properties into a small snippet of the larger XML document.
The z class has a render() method which combines the properties into
the XML snippet. I have a Render view configured to run this method,
and it works. (Though for some reason it adds a htmlhead..., which
I'd really like to get rid of. How can I?)
I've written the index_html to collect the individual objects and
concatenate their contents into an XML document. The code for the
method is below:
?xml version="1.0"?
espsetup-list
dtml-in "PARENTS[0].objectValues('ESPPackage')" sort=title
dtml-var "_[_['id']].render()"
/dtml-in
/espsetup-list
This almost gives me what I want (I say "almost" because everything
works, short of the render() call.) Viewing this results in:

I have a title variable in the z class which this index.xml method is
referencing. And, as previously stated, the render() method runs
without errors when invoked via the view. Yet, trying to display this
document from within another doesn't work. Can anyone please advise?
Thanks a bunch in advance.

[Zope] Site search
I followed the helpful instructions in the Z Catalog tutorial concerning adding searching to my site, and it works, though not in the way that I'd like. I've added the raw field to the list of searched indices, and chosen to only index DTML documents. Yet, all of my searches seem to be case sensitive, and they all seem to be 'and' searches. I'm not particularly interested in supporting boolean keywords, but since my site isn't that large, it might make more sense to treat searches as 'or' searches by default. How difficult is it to implement case insensitive searches in this manner? Also, I've noticed that DTML documents don't appear to automatically add themselves to the Z catalog. My understanding is that all Z catalog-aware classes automatically notify the catalog when they are created; are DTML documents and methods not catalog-aware?
