Teaching sqlobject inheritance to CatWalk

Reported by: victor.kryukov Owned by: anonymous
Priority: normal Milestone: 1.x
Component: Toolbox.Catwalk Version: 1.0
Severity: minor Keywords: catwalk, sqlobject, inheritance

Description (last modified by Chris Arndt) (diff)


  1. _inheritance=False should be added to your own class to avoid CatWalk crashing on your inherited user/group/permission table.
  2. CatWalk does not understand sqlobject inheritance.


I'm trying to integrate identity into my existing project. I've successfully followed the wiki (http://trac.turbogears.org/turbogears/wiki/IdentityManagement) with idtest project and are now customizing identity model for my app:

  1. I've added

to the letsmeet\config.py as suggested.

  1. I've modified my existing Account class, so now it look like that:
class Account(TG_User):
    tasks = MultipleJoin('Task')
    <... various model-specific methods ...>
  1. Now, if I would try to select Account in the CatWalk, I'm receiving the following error message:
Fail to load object instance: column account.child_name does not exist.
  1. As explained here  http://sqlobject.org/Inheritance.html, one should add _inheritance=False at the inherited class in order to avoid child_name automatic creation.
  1. Now, CatWalk works - but doesn't show anything interesting when selecting Account model; in particular, you cannot use CatWalk to create new account and should use old good tg-admin shell.
  1. It would be fun to have CatWalk that understands sqlobject inheritance some day, though I'm sure it shouldn't be expected before 1.1 given all existing priority tasks.

Cruft ticket. though I can still reproduce the described problem, CatWalk is not actively maintained any more and won't grow any new features. Closing as wontfix.
