Oops I missed something, you are creating a different table all together
for *Owner*. In that case you need to insert owner record (This is not
recommended, since the data is going to be the exact copy of User. This
will cause data inconsistency, use User instead)
class CreateDog(CreateView):
template_name = 'dogs_cats/create_dog.html'
model = Dog
fields = ('name', 'bday')
def form_valid(self, form):
*owner = Owner.objects.create_user(self.request.user.username,
self.request.user.email, self.request.user.password)*
* form.instance.owner = owner*
return super(CreateDog, self).form_valid(form)
But I would say this approach is wrong, your *Owner* is exact copy of *User*.
Use *User* instead.
The ideal way should be,
*class Cat(models.Model): name = models.CharField(max_length=40) bday
= models.DateField() owner = models.ForeignKey(User,
related_name='cats', on_delete=models.CASCADE)*
*class CreateDog(CreateView): template_name =
'dogs_cats/create_dog.html' model = Dog*
* fields = ('name', 'bday')*
* def form_valid(self, form): form.instance.owner =
self.request.user return super(CreateDog, self).form_valid(form)*
