Django create_superuser() missing 1 required positional argument: 'username'

Question

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager

# Create your models here.

class MyAccountManager(BaseUserManager):
    def create_user(self, email, username, password=None):
        if not email:
            raise ValueError('user must have smartcard')
        if not username:
            raise ValueError('must have username')

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

        )

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

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


class Account(AbstractBaseUser):

    username = models.CharField(max_length=100, unique=True)

    email = models.EmailField(verbose_name="email", max_length=30, unique=True)
    department = models.CharField(max_length=30, choices=DEPARTMENT)

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

    objects=MyAccountManager()

    def __str__(self):
        return self.email   

    def has_perm(self, perm, obj=None):
        return self.is_admin

    def has_module_perms(self, app_label):
        return True

I just can't get what is wrong.

While creating a superuser the prompt doesnt ask me for entering username

I modified the settings.py file as well. Tried several times with various databases. I have also added the username in REQUIRED_FIELDS section.

Welcome to SO, @Omkar.

You just need to change the fields REQUIRED_FIELD to REQUIRED_FIELDS.

REQUIRED_FIELDS = ['username']

You can check it on the docs.

@Omkar Kale, Please look your method:

def create_superuser(self, email, username, password):
    user = self.create_user(
        email=self.normalize_email(email),
        password=password,
        username=username,
    )

Please change it:

 def create_superuser(self, username, email, password):

    user = self.create_user(
        username=username,
        email=self.normalize_email(email),
        password=password,

        )

Look, you need to pass value according to the parameter. So

first: username,
second: email
third password.

Then you will no longer going to receive error for positional argument. you have to pass them according to the position of the parameter.

This doesn't solve the problem in the question, but is good advice in general — consistent order of arguments. — aaron, Dec 13 '19 at 06:33
