“add” button for related fields in admin interface should send 'limit_choices_to' parameter to add form

[Marco Aurélio de Araújo Silva]

I think it's self-explanatory. When the related field has a 'limit_choices_to' parameter, the new object added to the related class should have that field pre-defined with the 'limit_choices_to' value.

Makes sense to me, and verified that this is indeed not happening already.

The correct way of doing this would be to convert limit_choices_to to form level constraints and not to populate concerned fields.

i.e. how would you populate a field based on limit_choices_to = {'integer_field__gte': 3}?

[Greg Chapple]

charettes, how would you convert limit_choices_to in the way you mention?

[Simon Charette]

@gchp, Django doesn't provide any helper to do such a thing which might be the reason why this feature hasn't been implemented yet.

I was just pointing out that converting limit_choices_to to form initial data is a naive approach since you're not enforcing anything and that it has many limitations such as the one provided above.

[Greg Chapple]

@charettes, fair enough. I'll give it a go, anyways!

Maybe this will solve #29 :)
