I wanted to do the same thing. Here was my solution. Relevant part of
my custom User class:
# stuff below is to make Identity integration easier
@staticmethod
def byUserId(user_id):
"Returns a User object from a user_id."
return User.byEmail(user_id)
def _set_userId(self, user_id):
"Sets the user id (well, email)."
self.email = user_id
def _get_userId(self):
"Returns the email."
return self.email
# groups this user belongs to
groups= RelatedJoin( "Group")
I think I had to make a custom group too, as the mapping from user to
group wasn't automatic. In any case, here is my group class:
class Group(SQLObject):
class sqlmeta:
table="group_tbl"
groupId= UnicodeCol( length=16, alternateID=True )
displayName= UnicodeCol( length=255 )
created= DateTimeCol( default=datetime.now )
# collection of all users belonging to this group
users= RelatedJoin("User")
# collection of all permissions for this group
permissions= RelatedJoin( "TG_Permission", joinColumn="group_id",
intermediateTable="tg_group_permission",
otherColumn="permission_id" )
