#4787: Updating queryset on a ModelChoiceField
----------------------------------------+-----------------------------------
Reporter: fero <[EMAIL PROTECTED]> | Owner: adrian
Status: new | Component: django.newforms
Version: SVN | Keywords: ModelChoiceField
Queryset
Stage: Unreviewed | Has_patch: 1

{{{
The problem is that updating the queryset for a forms.ModelChoiceField in
a form doesn't change widget choices because they are set at
ModelChoiceField __init__ time.
This code works (in __init__ of my form):
MyForm.base_fields['activity'].queryset =
Activity.objects.filter(user__id=2)
MyForm.base_fields['activity'].widget.choices =
MyForm.base_fields['activity'].choices
So I propose the following patch in newforms/models.py
(I've never used "property" before)
class ModelChoiceField(ChoiceField):
.....
def _set_queryset(self, value):
self._queryset = value
self.widget.choices = self.choices
def _get_queryset(self):
return self._queryset
queryset = property(_get_queryset, _set_queryset)
}}}
