This example makes the users register and login
using the email instead of the default username



 

from django_registration.views import RegistrationView
from django_registration.backends.activation.views import *


class MyRegistrationView(RegistrationView):

    def create_inactive_user(self, form):
        """
        Create the inactive user account and send an email containing
        activation instructions.
        """
        new_user = form.save(commit=False)
        new_user.is_active = False
        new_user.username = new_user.email
        new_user.save()

        self.send_activation_email(new_user)

        return new_user

from django.contrib.auth.models import User
from django_registration.forms import RegistrationFormUniqueEmail



class MyRegistrationForm(RegistrationFormUniqueEmail):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['password1'].help_text = None
        self.fields['password2'].help_text = None
        self.fields.pop(User.USERNAME_FIELD, None)


from django import forms
from django.contrib.auth.forms import AuthenticationForm


class MyAuthenticationForm(AuthenticationForm):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['username'].label = "Email"
        self.fields['username'].widget = forms.EmailInput(attrs={'class': 'form-control'})

from django.contrib.auth import views as auth_views

from polls.views import *
from polls.forms import *

urlpatterns = [
    ...
    path('accounts/register/', MyRegistrationView.as_view(form_class=MyRegistrationForm), name='registration_register'),
    path('accounts/', include('django_registration.backends.activation.urls')),
    path('accounts/login/', auth_views.LoginView.as_view(template_name="registration/login.html", form_class=MyAuthenticationForm, redirect_authenticated_user=True), name='login'),
    path('accounts/', include('django.contrib.auth.urls')),
    ...


]

Keep in mind that the previously created super user username is not the email.
For this reason super users can only login through the admin interface.
