What relationship does this have with the context that a new > ZClass instance is created in? "class2" is looked up in this namespace. The top element is asked first for "class2". "class2" is found (by acquisition) from your "class1" Z instance (called "i1"). Thus, what is actually called is (class2 __of__ i1).createInObjectManager(....) "createInObjectManager" looks in "(class2 __of__ i1).aq_parent" (this is "i1") for "_setObject". Apparently, it does not find it there. Then it looks at "i1.aq_parent" (this is the folder, "i1" is contained in). There, it has success and creates the object. Dieter

I think this is a known limitation. I'm not sure. It is, unfortunately this is only mentioned under "status" in the ZCatalog interface. Well, I just got there by chance after several hours of digging around. I first thought perhaps some DTML-Document was "bad-behaving". (not that I had an idea how it might do that.) With a (assumed) growing attractiveness of things like sql-based UserFolders, perhaps a big warning sign either on the main page of these products or ZCatalog (better IMO, since this is a default product) would be in order, I guess. Or perhaps disabling subtransactions by default. All in all this combination seems not uncommon. >> Now I use SQL-based LoginManager, but why on earth did it only >> fail on DTML-Documents?

It creates the new object (usually, exception when its object has a special "Destination" attribute) in the parent (aq_parent) of its object. Your "dtml-with" should place your "class1" instance correctly in the "parent position". I expect, that your "class1" does not inherit form "ObjectManager" and therefore does not have a "_setObject". In this case, "createInObjectManager" goes up another step (another "aq_parent") and reaches the folder containing the "class1" instance. It has a "_setObject", the "class2" instance is placed there, too. > Anymore info (or pointers to better docs) would be great. Thanks. You can learn about "aq_parent" in the acquisition documentation. Search "zope.org" for it (acquisition). Dieter

I tried it out: For me, it was definitely an AND. What I did: Make a search for "Meta Type=Document Template" => lots of hits. Add "Title=xxxx" to the search => no hits Add "Title=Elvis" => some hits as I would expect. Dieter

ZCatalog and dates
by James Sintz 28 Nov '00

28 Nov '00

I have a ZCatalog set up to index a date field and a title field. When I do a search for meta_type "news" I get a tabular list back of all 18 cataloged items showing, among other things the date field (goLiveDate) and the title field. If I do a search for both meta_type of "news" a date of 2000/11/16 in the goLiveDate field the results page returns "There was no data matching this Catalog query". Yet when I do a search for the meta_type of "news" alone I see that indeed the Catalog contains 2 entries with 2000/11/16 in the goLiveDate field. Why doesn't it find any entries when I search by date? Jamey

I updated Zope ver. 2.2.0 to ver. 2.2.4 and my ODBC problems went away. Works great. Doing database integration is going to be a lot easier with Zope compared to Perl/CGI. Zope is a beautiful thing. Thanks for the help, P. Johnson

RE: [Zope] ZCatalog and dates

They are a date type. The date index or goLiveDate index is now a keyword index instead of a text index. However, when I try to find items of the meta_type "news" to catalog I get an AttributeError with an error value of __getitem__  What am I doning wrong??

change object ownership from DTML?
by Kyler B. Laird 28 Nov '00

28 Nov '00

I'm allowing users to initialize their own folders, but I've run into a problem with ownership. If I simply do manage_addFolder(), the folder is created "unowned". I feel like I've looked everywhere for a clue on how to set the ownership, but I haven't caught it. Surely I'm missing something incredibly obvious (to everyone else). Anyone want to enlighten me? I'd especially appreciate a pointer to how I should have figured this out on my own. Thank you. --kyler
