Thanks for the direction, Gary. :)
Getting a Choice field working in doctests was quite a
challenge. It now fails as only as a zc.table
FieldColumn. I'm including the relevant doctests and

Hi list,
For some reason, everytime an object is modified, all
of the catalog information for that object is lost.
A full catalog reindex works.
Do I need to subscribe the interfaces of the catalog
indexes to the ObjectModfiedEvent or something? I
appreciate any pointers.
Thanks,

[Zope3-Users] Extent catalog question
In my experience (zope2), large full textindexes require more and more cpu time for every new object added to the point where it takes several minutes for each new article uploaded! To avoid this problem, I was hoping to break the index into smaller pieces by using extent catalogs to filter by year. Can extent catalogs help mitigate a scaling issue like this? I've been able to instanciate one extent catalog per year, but it doesn't automatically index content like a normal Catalog. It requires a manual reindex. And to automate indexing content, do I need to implement something like these for an extent catalog?

Re: [Zope3-Users] Nested lists- "iteration over non-sequence"
Hi, Yes, one solution is custom widgets. Although I don't have a List of List example, I do have a List of Object example. It uses formlib, CustomWidgetFactory, ListSequenceWidget and ObjectWidget http://zope3demos.googlecode.com/svn/tags/zope3demos-200610-21/otherdemos/objectsofobjects2/ Project at http://zope3demos.googlecode.com/ Kevin Smith - Original Message From: Daniel M <[EMAIL PROTECTED]> To: zope3-users@zope.org Sent: Friday, October 20, 2006 2:47:36 PM Subject: [Zope3-Users] Nested lists- "iteration over non-sequence" Hello, I'm new to Zope, and using Zope 3.3. I have managed to get a simple site running. I am having trouble getting the web interface to let me edit an object that contains a list, where the type of values in the list, is an interface that also holds a list. I can’t get this “list inside a list” setup to work correctly. In my example, I have a Person object that contains a list of PersonInfo objects, where each PersonInfo contains a list of names. When I enter the view for Person (based on EditForm), it displays an edit form as I would expect. However, when I try to add a PersonInfo to the list via the interface, an exception is raised: “TypeError: iteration over non-sequence” (The full traceback is over 6 pages long, so I won’t post it, but it does mention “sequencewidget” many times). I've tried some variations to narrow down the problem: *If I change PersonInfo to hold just a string instead of a list, it works! *If I change Person to hold just a single PersonInfo instead of a list, it works! * Therefore, it seems like my Zope site is set up OK, but for some reason Lists of objects with Lists raise an exception. Am I missing something? Maybe I have to write some custom widget to get around this? Is this possibly a known problem? The code: ** People.py * class IPersonInfo(interface.Interface): names = schema.List( title=u"names", unique=False, value_type=schema.TextLine(title=u'name') ) class IPerson(interface.Interface): ID = schema.TextLine( title=u'ID', description=u'Persons ID code') the_list = schema.List( title=u"PersonInfo list", unique=False, value_type=schema.Object(IPersonInfo)) class PersonInfo(persistent.Persistent): interface.implements(IPersonInfo) def __init__(self): self.names = persistent.list.PersistentList() def PersonInfoWidget(context,obj,request): return ObjectWidget(context, request, PersonInfo) class Person(persistent.Persistent): interface.implements(IPerson) ID = "1-2-3" def __init__(self): self.the_list = persistent.list.PersistentList() class AutoEditView(form.EditForm): form_fields = form.Fields(IPerson) class PersonInfoView(form.EditForm): form_fields = form.Fields(IPersonInfo) ** end People.py * configure.zcml doesn’t do anything unusual, it sets up the views to use my custom widgets and sets up the edit views and security.

I think the layer attribute may be missing.

I think I must be missing something about the way skins work now. I've created a master page that I can load when I don't specify a skin, but when I do specify a skin (++skin++MySkin), it is unable to find the page (404). Here's a rough approximation of my ZCML: There's lots more, and if any of it would be relevant, let me know, but this seems like it's the crucial part. I know it is finding the skin itself successfully, because the error message is not the standard Rotterdam one. The skin I'm using is currently just inherits from z3c.layer.minimal. I'll keep on trying things, but it's all kind of a shot in the dark right now.

Re: [Zope3-Users] Intended scope of viewlets?
Hi Alec, Zope3demos has been updated with a stripped down example of Jürgen at Lovely Systems "no macro" masterpage design. You can get it from the trunk at svn checkout http://zope3demos.googlecode.com/svn/trunk/ zope3demos Should be good as of R35. FYI: There was a major refactoring of the package layout and url names. e.g. the index page is now reachable from http://localhost:8080/@@z3d.index.html Requires: z3c.viewtemplate, zope.viewlet, zope.contentprovider project page/bug collector: http://code.google.com/p/zope3demos/ Kevin Smith Monterey County Weekly newspaper Director of New Media - Original Message From: Alec Munro <[EMAIL PROTECTED]> To: "zope3-users@zope.org" Sent: Thursday, October 5, 2006 9:23:12 AM Subject: [Zope3-Users] Intended scope of viewlets? Hi List, I'm just getting up to speed with viewlets, having read a thread here and there in the past about them. I've installed the examples provided on this list, and while I believe I understand how they work, I don't understand in what circumstances they are most useful. The viewlets in the examples are all very small, such as retrieving an formatting a single piece of information about an object. However, from some of the posts to this list, I get the impression they are also being used for more complex items, like navigation menus. Is there a recommended scope? Can they be described in a way such as "develop your templates up to point X, then use a viewlet for development of further depth?". In my case, I am developing a new skin for a project, and my experience with metal says to make the entire HTML page a macro with slots for content and navigation. Is there a comparable viewlet-based paradigm? Also, am I correct in stating that when working with viewlets, the only complete HTML page will be the primary skin file, with all viewlets based on snippets of HTML? My questions are fairly broad-ranging, I know, but I have thus far been unable to find a straightforward explanation of viewlets, in terms of how they relate to general site development.

Hi, How can I obtain the absolute_url of the context object in a content provider or in a viewlet ? For example, in the demo3 of zope3demos, the render() method of the viewlet returns self.context.__name__. ( http://zope3demos.googlecode.com/svn/trunk/demo3/demo.py ) How could I tell it to return the absolute_url instead of the __name__ ?

[Zope3-Users] testbrowser passes but view fails
I have a situation where the functional test passes but when the page is
actually viewed a ComponentLookupError is raised.
This test passes using zope.testbrowser

>>> 'ViewletDemo3' in browser.contents
True
A quick sanity check
>>> browser.open('http://localhost/@@z3d.demo3.index.html')
>>> 'does not exist' in browser.contents
False
When the actual page http://localhost/@@z3d.demo3.index.html is viewed, a
ComponentLookupError is raised

self.viewlets = rows
When MISSING is replaced with the correct name the functional tests pass and
the view
renders properly. I'm using Zope 3.3.0b2 on python 2.4.3
Am I missing something or is this a possible bug? Thanks.

Re: [Zope3-Users] Replacing Macros with Contentprovider
Thanks for your reply. So, when you say macros still excel for general O-wrap, do you mean things like style_slot, script_slot and body_slot or do you also include things like header_slot, navigation_slot, breadcrumb_slot and footer_slot as well? I'm a little confused as to whether render() from contentprovider must only provide a string or if a zpt can be used? If a zpt can be used, does the namepace "view" access the contentprovider object or the __parent__ view object? Is the namespace "context" available as the original object?
