Now I have some strange thing. I display my form, send post and try to save
it. But it doesn't save:/
Here's my code:
model:
class UserProvince(models.Model):
user = models.ForeignKey(User)
province = models.ForeignKey(Province)
class Meta:
unique_together = (('user', 'province'), )
def __unicode__(self):
return self.user.username + '/' + self.province.name
form:
class ProvinceForm(ModelForm):
def __init__(self, *args, **kwargs):
super(ProvinceForm, self).__init__(*args, **kwargs)
user_provinces =
UserProvince.objects.select_related().filter(user__exact=self.instance.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)
range_type = forms.CharField(initial='province',
widget=forms.HiddenInput())
class Meta:
model = UserProvince
fields = ('province',)
view:
if request.POST:
form = ProvinceForm(request.POST, instance=request.user)
if form.is_valid():
obj = form.save(commit=False)
obj.user = request.user
obj.save()
form is valid, but save method makes no effect :/
