Re: CRUD code feedback

override get_initial and set only the logged in user

class CreateDog(CreateView):

    .......

    def get_initial(self):

        initial_data = super(CreateDog, self).get_initial()

        initial_data["owner"] = [(self.request.user.id, self.request.user.username)]

        return initial_data

I updated my models. py

Pet_Owner = get_user_model()


class RegisteredUser(User, PermissionsMixin):

    def __str__(self):
        return self.username


class Dog(models.Model):
    name = models.CharField(max_length=40)
    bday = models.DateField()
    owner = models.ForeignKey(Pet_Owner, related_name='dogs', on_delete=models.CASCADE)

    def __str__(self):
        return self.name + ' - ' + str(self.owner)


class Cat(models.Model):

    owner = models.ForeignKey(Pet_Owner, related_name='cats', on_delete=models.CASCADE)

I can see all users as drop down list for owner field using Pet_Owner = get_user_model() .Problem is, it shows all the Users in the project not the only one who is currently logged in.

Its the reverse. If the owner is deleted, all the cats and dogs associated with the owner will be deleted.

Will try it now.

Quesion about the on_delete=models.CASCADE, does this mean that if I delete the pet (dog or cat) it will delete the owner who owns them?

Your create view do not accept owner as a input and according to your models, owner can be null. That's the problem. Include owner to your create view fields as shown below. Also you may consider making owner mandatory as mentioned in my previous response.


class CreateDog(CreateView):
    model = Dog
    fields = ('name', 'bday', 'owner')
    template_name = 'animals/dog_create.html'


class CreateCat(CreateView):
    model = Cat
    fields = ('name', 'bday', 'owner')
    template_name = 'animals/cat_create.html'

Thanks
