def with_user(self):
all_agents = EconomicAgent.objects.all()
ua_ids = []
for agent in all_agents:
if agent.users.all():
ua_ids.append(agent.id)
return EconomicAgent.objects.filter(id__in=ua_ids)
Moving the call to with_user to form.__init__ solved the problem in the
form ModelChoiceField.
These questions remain unanswered, although I intend to do a bunch more
testing:
1. How pervasive is this problem? Does it affect template variables like
{{ object.foreign_key_method }} where the foreign_key_method returns a
queryset?
2. Is this behavior clearly documented anywhere?
