Hello Guys, i found some thread online, and i tried more than once and failed, i think its easy overall but i am still locked :S Trying to authenticate users with either email or username. When i say Users i got a custom user, base user + profile with just a few more info about the user submitted through registration form: class ProfiloUtente(models.Model): user = models.OneToOneField(User, related\_name=‘profile’, on\_delete=models.CASCADE) utente = models.ForeignKey(Utente, on\_delete=models.CASCADE) studio = models.ManyToManyField(Studio) telefono\_fisso = models.CharField(max\_length=20, default=None, blank=True) telefono\_mobile = models.CharField(max\_length=20, default=None, blank=True) indirizzo = models.CharField(max\_length=40, default=None, blank=True) citta = models.CharField(max\_length=50, default=None, blank=True) cap = models.CharField(max\_length=5, default=None, blank=True) provincia = models.CharField(max\_length=30, default=None, blank=True) cod\_fiscale = models.CharField(max\_length=16, default=None, blank=True) p\_iva = models.CharField(max\_length=27, default=None, blank=True) def **str** (self): return self.user.username And this is my data about the default user fields: class RegistrationForm(UserCreationForm): email = forms.EmailField(required=True) first\_name = forms.CharField(max\_length=30, required=True) last\_name = forms.CharField(max\_length=100, required=True) ``` class Meta: model = User fields = ( 'username', 'email', 'first_name', 'last_name', 'password1', 'password2', ) ``` … … The login form is the django default login with username + psw. Could someone help me understanding what i could do to extend the field username to also take the email into it? Thanks ---

Are you talking about allowing users to login to the site using either their username or their email address? If so, my first attempt on this would be to create a custom AuthenticationForm that inherits from the built-in [AuthenticationForm](https://github.com/django/django/blob/06c8565a4650b359bdfa59f9707eaa0d1dfd7223/django/contrib/auth/forms.py#L173), overriding the [clean](https://github.com/django/django/blob/06c8565a4650b359bdfa59f9707eaa0d1dfd7223/django/contrib/auth/forms.py#L210) method to try authenticating the person both ways and allowing them to be logged in if either attempt worked.

may you help me to get a better understanding of what i should do? on a large scale i could understand but when it comes to practice i don’t know how to move myself through it. Ill repost with some code snippets ---

When you do post code snippets, please insert them between lines containing only 3 backticks - ```. (Make sure you use the backtick - ` and not the apostrophe - '.) That means you would have one line with the 3 backticks, your code, and then one more line with just the 3 backticks. That allows this forum software to format your code nicely: ````auto # The line above this is just ``` def function(parm): return parm # The line after this is just ``` ```` So yes, go ahead and post what you’ve got and we can work forward from there.

Sry Ken, i should have posted it here, but its a long thread and perhaps could help some other people if the visibility is about a post on it’s own. I’ll link it here > [@Django Username or Email Authenticate](https://forum.djangoproject.com/t/django-username-or-email-authenticate/2775): > > i’m struggling a bit with this problem, some says i have to override AuthenticationForm but i don’t know how cause i got a custom user registration and login, i’ll post it: urls.py urlpatterns = [ path('login/', LoginView.as\_view(), {'template\_name': 'accounts/login.html'}, name='login'), Note im using default loginview right now. So in views.py i must have this def login(request): return render(request, '/login.html') ... ... Of course login.html is just like this \
