Sure, just give the modelchoicefield Topic.objects.all() to start
with, as this will never actually get used.

Dynamic queryset to ModelChoiceField

[shabda]

I have a form where I want to do something like,

class SetDefaultForm(forms.Form):
topics = forms.ModelChoiceField()

def __init__(self, user):
super(SetDefaultForm, self).__init__()
self.fields['topics'].queryset = Topic.objects.filter(user)

This does not work, of course, as ModelChoiceField has queryset as
required argument.

So I have to do something like,

class SetDefaultForm(forms.Form):
topics = forms.ChoiceField()

def __init__(self, user):
super(SetDefaultForm, self).__init__()
self.fields['topics'].choices= [topic for topic in
Topic.objects.filter(user)]

Is there a better way?
