Thanks for the quick answer.
I've checked col.py to learn how its done and I'm a little bit
confused how complicated its realized.
Is where a special reason why database driven constraints are
used ?
If the list of choices changes you have to update the
constraint check in the db. This isn't funny with production
systems.
Why not using a simple python statement like:
if not value in list_of_choices:
raise someException
Totally compatible with every database and easy to maintain.
Sorry if i'm asking stupid questions.
