Why is Django giving me: 'first_name' is an invalid keyword argument for this function?

I'm trying to create a custom user profile and have modified the example only slightly

from django.conf import settings from django.db import models from django.contrib.auth.models import BaseUserManager, AbstractBaseUser class MyUserManager(BaseUserManager): def create_user(self, email, password=None, first_name=None, last_name=None): if not email: raise ValueError('Users must have an email address') user = self.model( email=MyUserManager.normalize_email(email), first_name=first_name, last_name=last_name, #date_of_birth=date_of_birth, ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, password, first_name=None, last_name=None): user = self.create_user(email, password=password, first_name=first_name, last_name=last_name, #date_of_birth=date_of_birth ) user.is_admin = True user.save(using=self._db) return user class MyUser(AbstractBaseUser): email = models.EmailField( verbose_name='email address', max_length=255, unique=True, db_index=True, ) first_name=models.CharField(max_length = 30), last_name=models.CharField(max_length = 30), #date_of_birth = models.DateField() is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) objects = MyUserManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] def get_full_name(self): # The user is identified by their email address return self.email def get_short_name(self): # The user is identified by their email address return self.email def __unicode__(self): return self.email def has_perm(self, perm, obj=None): "Does the user have a specific permission?" # Simplest possible answer: Yes, always return True def has_module_perms(self, app_label): "Does the user have permissions to view the app `app_label`?" # Simplest possible answer: Yes, always return True @property def is_staff(self): "Is the user a member of staff?" # Simplest possible answer: All admins are staff return self.is_admin

When I try to run syncdb I get the following error:

You just installed Django's auth system, which means you don't have any superusers defined. Would you like to create one now? (yes/no): yes Email address: uou@pce.com Password: Password (again): TypeError: 'first_name' is an invalid keyword argument for this function

I have struggled to debug this because of the limited nature of the error message. I feel I'm making a simple mistake what am I doing wrong?


You are trying to set None (Null) value into first_name and it seems that this property don't allow it.

Try this changes:

class MyUserManager(BaseUserManager): def create_user(self, email, password=None, first_name='', last_name=''):

In model:

first_name=models.CharField(max_length = 30, blank = True)
