Django login with email or username
My new django project requires users to log in using their username or email. I googled and searched SO for a solution. But most of them were for authentication using email or creating a new backend. I wanted to allow my users to log in using email or username and I am too lazy to write a new authentication backend. So I extended default django authentication form . And with the help of this snippet I came up with this solution. And obviously emails for users are made unique.
forms.py
from django.utils.translation import ugettext, ugettext_lazy as _ from django.contrib.auth.forms import AuthenticationForm from django.contrib.auth import authenticate class MyAuthenticationForm(AuthenticationForm): username = forms.CharField(label=_("Username"), max_length=100) #max length changed from 30 to 100 def clean(self): username = self.cleaned_data.get('username').lower() password = self.cleaned_data.get('password') if username and password: #modifying clean method #next 5 lines are added if '@' in username:#checking if email try: #getting username from the User object for that email username = User.objects.get(email=username).username except: User.DoesNotExist self.user_cache = authenticate(username=username, password=password) if self.user_cache is None: raise forms.ValidationError( self.error_messages['invalid_login']) elif not self.user_cache.is_active: raise forms.ValidationError(self.error_messages['inactive']) self.check_for_test_cookie() return self.cleaned_data
urls.py
url(r'^login/$', 'django.contrib.auth.views.login', {'authentication_form':MyAuthenticationForm }),
Happy coding.:)
