#10112: Python Crash with ORM Inheritance -------------------------------------------+-------------------------------- Reporter: [email protected] | Owner: nobody Status: new | Milestone: post-1.0 Component: Database layer (models, ORM) | Version: 1.0 Keywords: | Stage: Unreviewed Has_patch: 0 | -------------------------------------------+-------------------------------- This bug causes a reproducible crash in the python interpreter [python issue5014] on my system, so I can't give a specific traceback, but I believe that an infinite recursion is generated when I try and use the db_column in a TextField.
Basically, I'm modifying one of my models to allow inheritance of a field so rather than keep the existing field which cannot be overridden with a function in the subclass, I'm creating a property to access the field - ie: class Foo(model): _bar = TextField(db_column = 'bar') bar = property(lambda x: x.bar) class Bla(Foo): @property def bar(self): whatever I think the db_column = 'bar' causes problems as there is a Foo.bar attribute so somewhere in the model this is screwing things up by making an infinite loop which for some reason is breaking the python runtime.
