Django Registration Redux: how to change the unique identifier from username to email and use email as login

Question

I\'m using django-registration-redux in my project for user registration. It uses default User model which use username as the unique

Answer 1

You can override registration form like this

from registration.forms import RegistrationForm
class MyRegForm(RegistrationForm):
    username = forms.CharField(max_length=254, required=False, widget=forms.HiddenInput())

    def clean_email(self):
        email = self.cleaned_data['email']
        self.cleaned_data['username'] = email
        return email

And then add this to settings file (read this link for details)

REGISTRATION_FORM = 'app.forms.MyRegForm'

This will set the email to username field as well and then everything will work as email is now the username.

The only problem is that username field has a max lenght of 30 in DB. So emails longer than 30 chars will raise DB exception. To solve that override the user model (read this for details).
