This may be difficult, because you must switch locales at runtime (which is possible). However, as far as I know, locale switching is not thread safe. This would mean, you are not on the safe side inside Zope. Dieter

Re: [Zope-dev] Subclassing LoginManager

I just didn't realize that the PTK was set up to require cookie logins, so I was trying to avoid them and solve the simpler piece of the problem first :-( Oh well, that's working fine now. I can log in, but it looks like permissions aren't getting set/propagated correctly: The initial management user is created with roles: ['Member', 'Manager', 'Reviewer'] My PersistentUserSource returns this list correctly as the roles list. All of the following are in Zope 2.1.6: 1. If I create the Portal as superuser with the Portal manager having the same username as me, then log in to the portal in a new browser I can see my folder but don't even have the permission to create new objects in it. 2. If I create the Portal as me, a site Manager, with the Portal manager having my user name, then log in as above, I can create objects but clearly don't have Reviewer rights. 3. If I create the Portal as me with the Portal manager having another username, then log in as above, it's just like the first case. I can see my folder but can't create anything in it. Any idea what I'm doing wrong now?

Shane: Holy cripe! I just saw a huge drop (half the available mem) and went to the Undo tab to see what was going on. The last transaction was my /Control_Panel/Database/manage_cache_age. Then I went to the manage_debug and my DateTime.DateTime.DateTime is DateTime.DateTime.DateTime 2460 96200 +93740 while I'm writing this its up to: DateTime.DateTime.DateTime 2460 140945 +138485 Ahhh! -- Jason Spisak 444(a)hiretechs.com

ZPatterns framework improvements
by Jephte CLAIN 22 May '00

22 May '00

sorry, I can't reproduce the error I talked about yesterday. All the insights given by philip has lighted up my path :-) There are four points I want to discuss: *** Some thought about RackMountables: they should subclass Acquisition.Implicit for bobotraversing to work. indeed, the __bobo_traverse__ code says: return getattr(ob, 'aq_base', ob).__of__(self) ob has the __of__ attribute only if it subclass an extension class (Acquisition.Implicit is an easy choice) *** in AttributeProviders.py, around line 199, definition of _DelAttributeFor is bogus. Instead of: def _DelAttributeFor(self,client,name): return self.aq_parent.aq_parent._SetAttributeFor(client,name) it should read: def _DelAttributeFor(self,client,name): return self.aq_parent.aq_parent._DelAttributeFor(client,name) *** It is desirable for me to enumerate the objects stored in the racks for a specialist. Because the __readableStorage is not accessible from derived classes (magic of ExtensionClasses ???), I can't add that behavior without patching Rack.py I'm thinking of a method 'rsValues' that enumerate values in the readableStorage. In Rack.Rack: def rsValues(self): """rsValues like 'readableStorageValues' why on earth are there __readableStorage and __writableStorage ??? """ values = [] slots = self.__readableStorage.values() for slot in slots: # the following took from retrieveItem item = slot[SelfKey] item._setSlot(slot) item._clearPerTransactionCache() # associate the rack to the item item._setRack(getattr(self, 'aq_inner', self)) ## the above line could be written # item._setRack(self.aq_inner) ## if racks objects where always wrapped. values.append(item) return values Or is it best to create a catalog in the specialist that index all objects stored in the rack as they get added? The default ZODB storage should give the ability to enumerate the objects, even if it does not belong to the standard "interface" of the rack. *** I understand now that the RackMountable is only a placeholder class, and that attributes and sheets are managed by AttributeProviders and SheetProviders, right? any comments? jephte clain minf7(a)educ.univ-reunion.fr

See the DataManagementEvents entry > in the new ZPatterns Wiki for details on how this will work. This design has the unfortunate side effect of coupling an object tightly to a single location. Properly speaking, objects shouldn't "know" about their containers; the container should be responsible for handling any operations which depend on it. Consider a Unix file system: the command to get rid of a file is "rm," which is an operation on the *directory*, not on the file/subdirectory; it only causes the file to be deleted if the current directory was the only one with a link to the file. CatalogAware is currently broken (as Evan just pointed out to me) because it tries too hard to know about its container's path; it would be better if the container were responsible for doing the index_object/reindex_object/unindex_object stuff, and not the object itself.

ZCatalog and Umlaut Problems
by Alexander Schad 22 May '00

22 May '00

Hi Folks! I experienced some problems using Umlauts (ä,ö,ü,ß) in ZCatalog. The problems seems to be that the umlauts get html_quoted when indexed i.e. u-umlaut becomes ü but when i search for an umlaut they get url_quoted u-umlaut becomes %FC and though the entry wont be found. Is that a bug?? What can i do to easily solve the problem ? thanks in advance, Alexander Schad

ZPatterns Wiki updated
by Phillip J. Eby 22 May '00

22 May '00

FYI, the ZPatterns Wiki at: http://www.zope.org/Members/pje/Wikis/ZPatterns/ Has been updated to reflect planned additions for 0.4.0, as well as more detail on things that are in 0.3.0 and 0.2.0. In particular, the PlugIns system has more documentation, and the entire DataManagers subsystem now has pages for each of the major players such as DataSkins, DataInjectors, IndexingAgents, RuleAgents, AttributeProviders, SheetProviders, etc. Please feel free to add questions or comments to the Wiki, or write me on the list(s). Thanks.

catlogged specialist and rack
by Jephte CLAIN 22 May '00

22 May '00

Hello, for those who are in a need for search and enumeration capabilities for specialist and racks in ZPatterns-0.3.0 right now like I am, the following could be interesting. Searchable.py defines: CatalogAwareAttributeProvider, CatalogAwareAcquiredAttributeProvider Attribute providers that recatalog the object when its attributes are changed CatalogAwareRack Rack that has a catalog inside it, and index the object created with newItem, and modified afterward. by default, only the id is catalogged. this can be changed in _setup for derived classes CatalogAwareSpecialist Specialist that has support for CatalogAwareRack. A tab 'Contents' provide support for enumerating the objecs in the racks. www/contents can be customized to allow, editing, adding, and/or deleting objects if you like. This, in fact, is a quick hack. remember that all these will be useless when ZPatterns-0.4.0 is out. But I'm fool enough to use evolving software still in infant stage... hope this is useful like it is for me. regards, jephte clain minf7(a)educ.univ-reunion.fr
