Try overriding your AddRestaurantForm's "save" method:
def save(self, commit=True):
self.instance.city = get_object_or_404(City,
name=self.instance.city)
# Finish by passing control back to the normal Django flow:
super(AddRestaurantForm, self).save(commit)
I think that'd work. Sometimes 'super' causes recursion errors in
Django, so if that gives you problems, try calling the method all by
itself:
# Finish by passing control back tot he normal Django flow:
forms.ModelForm.save(self, commit)
