I’m trying to customize django’s AbstractUser. When I try to reset username
to None
, I get the following exception:
"django.core.exceptions.FieldDoesNotExist: User has no field named 'username'".
Here is my code:
class UserManager(BaseUserManager): use_in_migrations = True def _create_user(self, email, password, **extra_fields): if not email: raise ValueError("L'adresse e-mail donnée doit etre definie") email = self.normalize_email(email) user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user def create_user(self, email, password, **extra_fields): extra_fields.setdefault("is_staff", False) extra_fields.setdefault("is_superuser", False) return self._create_user(email, password, **extra_fields) def create_superuser(self, email, password, **extra_fields): extra_fields.setdefault("is_staff", True) extra_fields.setdefault("is_superuser", True) if extra_fields.get("is_staff") is not True: raise ValueError("Superuser must have is_staff=True") if extra_fields.get("is_superuser") is not True: raise ValueError("Superuser must have is_superuser=True") return self._create_user(email, password, **extra_fields) class User(AbstractUser): username = None email = models.EmailField('email adress', unique=True) telephone = models.CharField(max_length=20) REQUIRED_FIELDS = []
What can I do to solve this problem?

Answer
You haven’t set a value for USERNAME_FIELD
in your code. This must be set to a field that uniquely identifies a user instance. AbstractUser
sets this to 'username'
and hence you are getting the error. You can set this to 'email'
to solve your problem:
class User(AbstractUser): username = None email = models.EmailField('email adress', unique=True) telephone = models.CharField(max_length=20) # set below value USERNAME_FIELD = 'email' REQUIRED_FIELDS = []
