Django Unknown field(s) (username) specified for PoUser - django

Question

I got this error because I create a custom usermodel, and When I got all setup, which I look into the django/contrib/auth/models.py, I set the email as USERNAME_FIELD, and REQUIRED_FIELD is some field that is not defined in AbstractBaseUser and PermissionMixin which my UserModel inherited, I can access all section except the 'Po User add section', and I put on my codes in models.py and admin.py and settings.py ,urls.py ,wish somebody could help.

Answer 1

The parent class (django.contrib.auth.admin.UserAdmin) has an add_fieldsets attribute that includes the username field. Add an attribute to your MyUserAdmin class called add_fieldsets and treat it like the fieldsets attribute: use it to define fields you want to show in the add form.
Note: If your username is set to email then add email to add_fieldsets.
See the note about add_fieldset at the "Customizing authentication in Django" docs page and the full example from the Django docs.

Answer 2

Add the add_fieldsets attribute to your adminModel class like below
from django.contrib.auth.admin import UserAdmin
class CustomUserAdmin(UserAdmin):
...
# add fields those needs to be visible while adding the data in form.
add_fieldsets = (
(None, {'fields': ('first_name', 'last_name', 'email', 'password', 'role', 'country_code', 'country',
'is_active', 'verified')}),
)
...
