I had a quick look, and it seems that limit_choices_to doesn't accept a callable (at least in the svn version I use at work, rev 9100 iirc). It can be a queryset or any object having a add_to_query(sqlquery) method, but I failed to find any object implementing this protocol in django itself, nor any documentation. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Perhaps someone will come with better idea, but for now to achieve this result i am modifying queryset in form derived from model: class SomeEditForm(ModelForm): class Meta: model = my_models.MyModel def __init__(self, *args, **kwargs): self.fields['author'].queryset = my_models.MyModel.objects.filter(user=self.tied_user) other thing to look at is that what is passed to limit_choices_to might be a callable, but it doesn't receive instance as parameter (and i would like it did). -- Maciej "Fiedzia" Dziardziel --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: referencing the current instance inside limit_choices_to
There is no way to have per-instance limit_choices_to.
