ERROR - DJANGO 2.0.9 - Typeerror: create_superuser() Missing 1 required positional argument: 'email'

Question

You can help me with this problem, I’m new to Django:

So, I’m taking an Internet course to create a distance learning platform to learn about Django. I am using the version Django 2.0.9, I have a problem during the creation of the super user, the course I am following using a version of Jango older than at the time of creation of the database socilitava the registration of the Administrator soon after. Old command:

$ python manage syncdb

But this command no longer exists (as I understand it), so I’m using the sequence of commands below:

$ python manage.py makemigrations
$ python manage.py migrate
$ python manage.py createsuperuser

I created a custom user and set as Django’s default user including the information AUTH_USER_MODEL = 'accounts.User' in py Settings., but the field email does not appear during super user creation and error occurs below:

Nome de Usuário: gabriel
Password: 
Password (again): 
Traceback (most recent call last):

**TypeError: create_superuser() missing 1 required positional argument: 'email'**

I tried to comment on the field REQUERID_FIELDS = ['email'] in the Custom User class, I deleted the database and migrated the data again, but it didn’t work, it keeps accusing the absence of the field email.

Follow Custom User model set as default:

from django.db import models

from django.contrib.auth.models import (AbstractBaseUser, PermissionsMixin, 
                                    UserManager)

class User(AbstractBaseUser, PermissionsMixin):

    username = models.CharField('Nome de Usuário', max_length=30, unique=True)
    email = models.EmailField('Email', unique=True)
    name = models.CharField('Nome', max_length=100, blank=True)
    is_active = models.BooleanField('Está ativo?', blank=True, default=True)
    is_staff = models.BooleanField('É da equipe?', blank=True, default=False)
    date_joined = models.DateField('Data de Cadastro', auto_now_add=True)

    objects = UserManager()

    USERNAME_FIELD = 'username'
    REQUERID_FIELDS = ['email']

    # Define a representação string do objeto
    def __str__ (self):
        return self.name or self.username

    def get_short_name(self):
        return self.username

    def get_full_name(self):
        return str(self)

    class Meta:  
        verbose_name = 'Usuário'  
        verbose_name_plural = 'Usuários'

Answer 1

In the definition of the User class, where you inform USER_NAME_FIELD, add EMAIL_FIELD, like this:

class User(AbstractBaseUser, PermissionsMixin):

    username = models.CharField('Nome de Usuário', max_length=30, unique=True)
    email = models.EmailField('Email', unique=True)
    name = models.CharField('Nome', max_length=100, blank=True)
    is_active = models.BooleanField('Está ativo?', blank=True, default=True)
    is_staff = models.BooleanField('É da equipe?', blank=True, default=False)
    date_joined = models.DateField('Data de Cadastro', auto_now_add=True)

    objects = UserManager()

    EMAIL_FIELD = 'email'  # ====> Acrescente essa linha
    USERNAME_FIELD = 'username'
    REQUERID_FIELDS = ['email']
    ....
