[Zope-dev] Fixed reply Re: [Zope-dev] Trouble setting LoginManager default user class

[Dan L. Pierson]

Oops, my reply of yesterday was missing the actual error I get using
manage_setStorage.  It's an AttributeError for aq_acquire!  I can't
see how I could be getting this since PersistentUserSource singly
inherits from BasicUserSource which inherits from Rack.  What happened 
to my aq_acquire?  Does it have to do with some mistake in the way I'm 
calling manage_addLoginManager?

Ah yes, forgot about this problem -- it was yesterday...

Here's my current code from DemoPortalBase.install:

        elif db == 'LoginManager':
            from Products.LoginManager.LoginManager import \
                 LoginManager, manage_addLoginManager
            from PersistentUserSource import PersistentUserSource
            self.MembersClass = LoginManager # maybe not needed anymore
            manage_addLoginManager(self,
                                   'Persistent User Source',
                                   ['Basic Auth Login'],
                                   0, 0, 0)
            #self.acl_users.manage_setStorage('DemoPortal/LoginMember')
            for us in self.acl_users.UserSourcesGroup.objectValues():
                if us.meta_type == 'Persistent User Source':
                    us.manage_setStorage('DemoPortal/LoginMember')
                    
The commented out line fails because it doesn't have a
manage_setStorage.  The uncommented out code causes the following
traceback.  It was after I hit this that I started hacking on
_defaultClass...  Probably I should have yelled for help then, but I
have this bad habit of digging myself in as far a possible first :-)
