Heres the the methods. Its designed so I can not show a link if the user
doesn't have permission view it. This will allow things my dynamic site map
to be relvent to the current user.
from AccessControl.Permission import Permission
import string
def canViewObj(SomeObject, userRoles):
if hasattr(SomeObject,'_View_Permission'):
Roles = getattr(SomeObject,'_View_Permission')
if 'Anonymous' in Roles:
return 1
else:
for i in userRoles:
if i in Roles:
return 1
# ok, try parents
if SomeObject.acquiredRolesAreUsedBy('View') != '':
return canViewObj(SomeObject.aq_parent, userRoles)
else:
return canViewObj(SomeObject.aq_parent, userRoles)
def canView(self, objName, AUTHENTICATED_USER):
return 1
#return AUTHENTICATED_USER.getRoles()
objName = 'self.'+string.replace(objName,'/','.')
objName = string.replace(objName,'..','.')
SomeObject = eval(objName)
return canViewObj(SomeObject, AUTHENTICATED_USER.getRoles())
def test(self, objName):
#return objName.getRoles()
objName = 'self.'+string.replace(objName,'/','.')
objName = string.replace(objName,'..','.')
SomeObject = eval(objName)
if hasattr(SomeObject,'_View_Permission'):
return 'blah'
return canViewObj(SomeObject,['Customer', 'Developer', 'Manager'])
-----------------------
I'm not sure that this caused the problem but it was what I was working on
at the time. I have a feeling that the problem may have been caused days
earlier. What I think happened is I did something to crash zope and then the
problem with initilization surfaced when I tried to reload. I think I even
saw something called a principia factory sitting in another section of the
site so that and the MailHost must have got transposed.

I did something similar before I got this message and managed to fix the
problem. I sent my ODB to support@digicool.com but its 10M zipped and it
bounced. I will forward it to you now.
