CustomerAdmin cannot find existing Field (admin.E116)

[Josephine-Marie]

I added a custom user model to a fresh django shop project made with cookiecutter but this error does not disappear no matter what I do:
<class 'shop.admin.defaults.customer.CustomerAdmin'>: (admin.E116) The value of 'list_filter[0]' refers to 'is_staff', which does not refer to a Field.

ofc my custom User model has:
is_staff = models.BooleanField(default=False)

From which model does your customized User model inherit?

The above error is really weird. Without additional details I can't imagine any reason.

first, thank you for your fast reply. My User Model inherits from AbstractBaseUser. my only steps were: I created a new project with cookiecutter, created a new app and filled models.py and admin.py with my custom User model / Useradmin / .... I set it as authusermodel in my settings and tried to makemigrations and this error keeps occuring no matter what I try. Below is my UserModel:

class User(AbstractBaseUser,PermissionsMixin):
        class Meta:
                db_table='auth_user'
        #required

Unless you need that User-model outside of django-SHOP, I'd rather propose to use the Customer model. You can inherit from shop.models.customer.BaseCustomer. Django-SHOP does this itself in shop.models.defaults.customer.Customer, so you can use that as blueprint.

If you really have to use the User-model, then inherit from django.contrib.auth.models.AbstractUser. Django-SHOP does this itself in email_auth.models.User.
Don't forget to point AUTH_USER_MODEL onto you User model.

Your code btw. contain far too much repetition, which is already implemented somewhere else. Remember to follow the DRY principle.
