Multiple USERNAME_FIELD in django user model

Question

My custom user model:

class MyUser(AbstractBaseUser):
    username = models.CharField(unique=True,max_length=30)
    email = models.EmailField(unique=True,ma         


        

Answer 1

No, you cannot have more than one field defined in USERNAME_FIELD.

One option would be to write your own custom login to check for both fields yourself. https://docs.djangoproject.com/en/1.8/topics/auth/customizing/

i.e. change the backend to your own. AUTHENTICATION_BACKENDS then write an authenticate method and check the username on both fields in the DB.

PS you may want to use unique_together on your model so you don't run into problems.

Another option would be to use the actual field username to store both string and email.
