这是我的model.py

class MyUserManager(BaseUserManager):
    def create_user(self, username, email, password=None):
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email       = self.normalize_email(email),
            username    = username,
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, username, email, password):
        user                = self.create_user(email,username=username, password=password)
        user.is_admin       = True
        user.save(using=self._db)
        return user

class Operator(AbstractBaseUser, PermissionsMixin):

    owner           = models.ForeignKey('Owner')
    kontraktor      = models.ForeignKey('Kontraktor')
    alphanumeric    = RegexValidator(r'^[0-9a-zA-Z]*$', message='hanya yang mengandung karakter alphanumeric')
    email           = models.EmailField(verbose_name='email address', unique=True, max_length=244)
    username        = models.CharField(unique=True, max_length=20, validators=[alphanumeric])
    first_name      = models.CharField(max_length=30, null=True, blank=True)
    last_name       = models.CharField(max_length=30, null=True, blank=True)
    date_of_birth   = models.DateTimeField(auto_now_add=True)
    date_joined     = models.DateTimeField(auto_now_add=True)
    is_active       = models.BooleanField(default=True, null=False)
    is_staff        = models.BooleanField(default=False, null=False)

    objects         = MyUserManager()

    USERNAME_FIELD  = 'email'
    REQUIRED_FIELD  = ['username']

    def get_full_name(self):
        fullname = self.first_name+" "+self.last_name
        return self.fullname

    def get_short_name(self):
        return self.username

    def __str__(self):
        return self.email

你能帮我解决这个问题吗?

REQUIRED_FIELD = ['username'] 

应更改为:

REQUIRED_FIELDS = ['username']
