Question

I have the following situation:

class Professor(models.Model):
    default_address = models.OneToOneField('Address')

class Address(models.Model):
    name = models.CharField()
    street_address = models.CharField()
    # ...
    professor = models.ForeignKey("Professor", related_name="addresses")

Basically, one Professor can have many Addresses associated with it, but only one default_address selected. However, things aren’t working right when I save things with my view, things don’t get associated just right:

form = forms.ProfileEditForm(request.POST)

if form.is_valid():
    address = professor.default_address or models.Address()
    address.name = "Default" if address.name == None else address.name
    address.street_address = form.cleaned_data['street_address']
    address.street_address_2 = form.cleaned_data['street_address_2']
    # ...
    address.save()

    professor.default_addresss = address
    professor.save()

After I save it, professor.default_address is None. What am I doing wrong here?

Answer 1

I needed to set user_profile on both the Address and the PhoneNumber before saving:

address.user_profile = user.profile
address.save()

phone_number.user_profile = user.profile
phone_number.save()

user.profile.default_address = address
user.profile.default_phone_number = phone_number
user.profile.save()
