I think it works. Thanks. What I did:
changed the form cal in view:
form_provinces_to_add = ProvinceForm(request.POST, user=request.user)
changed a form a little:
class ProvinceForm(ModelForm):
def __init__(self, *args, **kwargs):
self.user = kwargs.pop('user')
super(ProvinceForm, self).__init__(*args, **kwargs)
user_provinces =
UserProvince.objects.select_related().filter(user__exact=self.user.id).values_list('province')
self.fields['province'].queryset =
Province.objects.exclude(id__in=user_provinces).only('id', 'name')
province = forms.ModelChoiceField(queryset=None, empty_label=None,
label=_(u'Wybierz województwo'))
range_type = forms.CharField(initial='province',
widget=forms.HiddenInput())
class Meta:
model = UserProvince
fields = ('province',)
def save(self, commit=True):
foo = super(ProvinceForm, self).save(commit=False)
foo.user = self.user
if commit:
foo.save()
return foo
