I have these three models:
class Address(models.Model):
name = models.CharField(max_length=100)
## many other fields ##
class Meta:
ordering = ('name',)
def __unicode__(self):
return self.name
class Organization(models.Model):
name = models.CharField(max_length=100)
## many other fields ##
class Meta:
ordering = ('name',)
def __unicode__(self):
return self.name
class OrganizationAddress(Address):
organization = models.ForeignKey (
Organization,
related_name = "addresses",
)
When i try to add/edit an organization and add one addresses i've got
this error:
" ValueError: Cannot assign None:
"OrganizationAddress.address_ptr" does not allow null values. "
I've tried to understand the problem (because it happened since one day
to another..) and i've found that the problem was born after the django
commit of the changeset 9664.
Is a django's bug or i've made something wrong?
Below a code portion to test the problem.
"""
from django.forms.models import inlineformset_factory
from my_apps.models import Organization, Address, OrganizationAddress
Organization(name='test').save()
org = Organization.objects.get(name='test')
inline_formset = inlineformset_factory(Organization,
OrganizationAddress, can_delete=False, extra=2)
data = {
'addresses-TOTAL_FORMS': '2', # the number of forms rendered
'addresses-INITIAL_FORMS': '0', # the number of forms with initial data
'addresses-0-name': 'Test test',
}
formset = inline_formset(data, instance=org)
formset.is_valid()
formset.save()
"""
Sorry for my english...
Marco.
