The use of a literal anonymous list in methodb's signature for "objects" may have something to do with the results you're getting on conflict.

Of course!
I'm missing out on something here. Why is this an "of course"? What's a
"literal anonymous list"?
Consider this method:
def methodFoo(self, objects=[]):
# do stuff, including altering the list objects
The list that is assigned to "objects" in the definition of arguments is
only created once. There is only one instance of the list for all the
calls to methodFoo. If you alter that list, then it is altered for the
future too.
Try it in Python from the interactive prompt:
def foo(o=[]):
... o.append('x')
... print o
...
foo()
['x']
foo()
['x', 'x']
foo()
['x', 'x', 'x']

[Zope-dev] ZCatalog problems
Hi guys, I'm having trouble making ZCatalog work. The problem is that there are 29 objects of a given meta type, with the same booleans that should be returned for an iteration; but only 20 are.

Could be that your objects have different ideas of what are proper
boolean values.
I assume you're using a FieldIndex. Try calling
uniqueValuesFor(index_name) to see what values are stored. You may find
that you have 0, 1, '1' and '', for example.
In situations like that, I get the unique values, then construct a query
for the catalog based on the true or false values.
To get the true values, something like
Catalog(boolean_index=
filter(None, Catalog.uniqueValuesFor('boolean_index'))
To get the false ones:
Catalog(boolean_index=
filter(lambda x: not x,
Catalog.uniqueValuesFor('boolean_index'))

Re: [Zope-dev] catalog object owners?
getOwner should do it. This will return the actual owner object. It'd be preferable to catalog the tuple representing the owner path (this is returned by getOwner(1)), so you might want to create a method on the object that returns "getOwner(1)". - Original Message - From: "Tim McLaughlin" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, February 26, 2001 3:38 PM Subject: [Zope-dev] catalog object owners?

[Zope-dev] Search Features and Zope Directions Road Map
Zope is a great application server, the same as its soon to be released Content Management Framework, because of its bet on Python, everybody say it. Nevertheless, after reading the Directions Roadmap from DC, I was surprised that a substantial improvement of the searching features of Zope, wasn't mentioned as a major concern. For a new Zope enthusiast like me, it is a kind of addiction to arrange and administer content while taking the learning curve. Almost everybody in this list with a non-programming background might've experimented this. But when I arrived to the search features of ZCatalog, I got mixed feelings. (Right now I'm stuck on this OR indexes searching :) ) The fact is that - according to my strong belief - everybody uses more Google to look for Zope Site's content than Zope's own Zcatalog's search engine. Moreover, everybody uses more Google to look for everything, bypassing windows, doors, and portals!. Why? Because it's terribly smart (not mentioning its 6,000 Linux boxes, by the way), and because there's no need to follow the highly-engineered information architecture of a web site, if there's a trustful shorcut to the relevant content!. So, if I'd have to mention one big feature improvement to Zope, I wouldn't doubt: "search engine". I just wanted to point on this subject. I know Zope isn't about spidering and retrieving, but it should have "Greater Search Capabilities" as a title, within that roadmap. :) Ausum p.d. Right now I'm quite interested at the technology of searching and finding non structured content, in order to compose structured documents. For example, the guys at Vignette (StoryServer) say that its customers don't need to keyword anything in order to have a "related content" section. After the writer finishes a story, (possibly while) a routine by Autonomy (www.autonomy.com) reads the document and finds out what the document is about, and so it triggers a search for related content within the site, without the need of intervention by the writer. (For the curious, Autonomy has published a personal version of its software. It's called Kenjin (www.kenjin.com) ). On the other hand, Fast, from Norway, already have a nice multimedia search engine, from regular, non-structured, spidered web pages. Can we do that "structuring the unstructured" thing within Zope? ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
