Django user model custom fields names

How to rename fields of the user model?

I want to rename the fields

first_name to firstName, last_name to lastName with AbstractUser

class User(AbstractUser):
    email = models.EmailField('email address',unique=True)
    firstName = models.CharField("First Name", max_length=150)
    lastName = models.CharField("Last Name", max_length=150)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = [
        'username',
        'firstName',
        'lastName',
    ]

The above code works, but it does not rename the fields what it does is add the fields firstName and lastName

Any ideas or suggestions?

You can simply override the respective field in the inherited class and create a new field with a new name instead if you really don't want to use any alias name or db_column as Barney Szabolcs mentioned.

Therefore, we can override first_name and last_name with ' ' to avoid any exception error as they've been used in other areas — admin field_sets, get_full_name method, etc. Or you can also override them as well.

class User(AbstractUser):
    email = models.EmailField('email address', unique=True)
    first_name = ' '
    last_name = ' '
    firstName = models.CharField('First name', max_length=150)
    lastName = models.CharField('Last name', max_length=150)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = [
        'username',
        'firstName',
        'lastName',
    ]

Note that you must add the following line in the settings.py:

AUTH_USER_MODEL = '<respective-app-name>.User'

Moreover, to ensure that you can check the created migration file content.

I think you could use the db_column parameter, so you can hopefully override AbstractUser's default fields.

class User(AbstractUser):
    email = models.EmailField('email address',unique=True)
    first_name = models.CharField("First Name", db_column="firstName", max_length=150)
    last_name = models.CharField("Last Name", db_column="lastName", max_length=150)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = [
        'username',
        'firstName',
        'lastName',
    ]
