PropertyManagerEvents proposal: Last call for review
by Casey Duncan 10 May '01

10 May '01

I have a proposal up for discussion on adding hookable callbacks to property events. If you are interested in such topics as property validation, CatalogAware syncing on property changes, etc, please take a look within the next few days. I think this is something that many people could use, so your comments are valued. http://dev.zope.org/Wikis/DevSite/Proposals/PropertyManagerEvents Next week I would like to deliver the patch to implement this, so if you have something to say on this topic speak now! -- | Casey Duncan | Kaivo, Inc. | cduncan(a)kaivo.com `------------------>

Object dereferancing Question
by Jeff 10 May '01

10 May '01

Hi ya'll, I have created a product with a zclass that contains a zclass; classA contains classB. Both use 'Folder' as bases class. I want the classB objects to have a 'default rendering' capability so I added a DTML Method named index_html to classB with the following code: <dtml-var expr="_.getitem(template, 1)"> Where 'template' is a property of the object that has a method name in it. So far so good, if I navigate to a classB object the correct method is called and the object is rendered. Now for the part I don't understand..... I have a page where I would like dynamically display a classB object. I used the following: <dtml-var expr="_.getitem(index_object, 1)"> Where 'index_object' is the id of a classB object within the name space (same folder). I thought that this would call the 'default rendering' for the named object, but instead returns the object. The following code worked: <dtml-with expr="_.getitem(index_object, 0)"> <dtml-var index_html> </dtml-with> Why does the "_.getitem(index_object, 1)" not return the rendered object? Thanks, Jeff

Do you have multiple acl_users objects in the acquisition context of the object? Because if you do and the self.acl_users will acquire (possibly) the wrong user database. If that's not the problem, I'm gonna have to let it cook, and I'll probably come up w/ somethin' later. --Tim <plug> You could also try a ZUserFolder and use restrictedTraverse if you want. :-) </plug> -----Original Message----- From: Magnus Heino (Rivermen) [mailto:magnus.heino@rivermen.se] Sent: Thursday, May 10, 2001 9:23 AM To: 'Tim McLaughlin'; Magnus Heino (Rivermen) Cc: 'zope-dev(a)zope.org' Subject: SV: Subject: [Zope-dev] change ownership The one that comes with Zope. /Magnus > -----Ursprungligt meddelande----- > Från: Tim McLaughlin [mailto:tim@BCSWebservices.net] > Skickat: den 10 maj 2001 15:26 > Till: 'Magnus Heino (Rivermen)'; Tim McLaughlin > Kopia: 'zope-dev(a)zope.org' > Ämne: RE: Subject: [Zope-dev] change ownership > > > What kind of UserFolder are you using...

I call the external method like this from DTML... set_owner(restrictedTraverse(path_to_user)), where path to user is a physical path, but I'm using the ZUserFolder, so I can use the restrictedTraverse to get to users. UserFolder has a different API. You could do this if your acl_users is a standard UserFolder... set_owner(acl_users.getUser(user_name)) in DTML or make your external method this... def set_owner(self, user_name): self.changeOwnership(self.acl_users.getUser(user_name)) OK, so that should keep you busy for a while. Anyway, the point is that the parameter to changeOwnership is a User _object_. Good luck. --Tim -----Original Message----- From: Magnus Heino (Rivermen) [mailto:magnus.heino@rivermen.se] Sent: Thursday, May 10, 2001 7:25 AM To: 'Tim McLaughlin'; 'zope-dev(a)zope.org'; Magnus Heino (Rivermen) Subject: SV: Subject: [Zope-dev] change ownership I can get it to work :-/ I get an attributeerror on aq_inner in lib/python/AccessControl/Owned.py, line 302, in ownerInfo Seems as if the user i provide isn't of the right type?

win binaries for zope cvs
by Sin Hang Kin 09 May '01

09 May '01

It seems that the cvs is running with python 2.1 already, can someone provide the win binaries so we can test the current cvs? I think the current develope does not change the c extensions, so we could play around without wait until the 2.4 beta release.

Zope 2.4 and unicode merge
by Sin Hang Kin 09 May '01

09 May '01

Can DC merge the unicode.diff into zope 2.4 standard distribution? The current 0.5 diff seems not working, and since 2.4 is based on python 2.1 then it sounds reasonable to include unicode attributes as a core part of zope.
