Question

I’m working on some forms in Django. One field is a ForeignKey in the model, so represented as a ModelChoiceField in the form. The ModelChoiceField currently uses the __unicode__ method of the model to populate the list, which isn’t my desired behavior. I’d like to be able to use another method of the model. From the docs, it looks like I can force my own QuerySet, but I can’t see how this would help me use a method other than __unicode__.

I’d really rather avoid divorcing this from the default form methods if at all possible.

Any suggestions?

Not so much a custom queryset, but converting your queryset to a list. If you just do choices=some_queryset Django makes the choices in the form of:

(item.pk, item.__unicode__())

So just do it yourself with a list comprehension:

choices=[(item.pk, item.some_other_method()) for item in some_queryset]
