User authentication with either username or email.
Hi,
I created a backends.py in my project folder.
backends.py ::
*from django.conf import settings*
*from django.contrib.auth.models import User*
*
*
*class EmailOrUsernameModelBackend(object):*
*def authenticate(self, username=None, password=None):*
*if '@' in username:*
*kwargs = {'email': username}*
*else:*
*kwargs = {'username': username}*
*try:*
*user = User.objects.get(**kwargs)*
*if user.check_password(password):*
*return user*
*except User.DoesNotExist:*
*return None*
*
*
*def get_user(self, user_id):*
*try:*
*return User.objects.get(pk=user_id)*
*except User.DoesNotExist:*
*return None*
*
*
And in the views.py,
*from django.contrib import auth*
*from django.contrib.auth.models import User*
*from tangle.backends import EmailOrUsernameModelBackend*
*
*
*def authentication(request):*
*username = request.POST.get('username', '')*
*password = request.POST.get('password', '')*
*user = authenticate(username=username, password=password)*
*if user is not None:*
*auth.login(request, user)*
*return HttpResponseRedirect('/loggedin/')*
*else:*
*return HttpResponseRedirect('/invalid_login')*
*
*
Settings.py
*AUTHENTICATION_BACKENDS = (*
*'backends.EmailOrUsernameModelBackend',*
*'django.contrib.auth.backends.ModelBackend'*
*)*
*
*
Now when I login using either username or email it shows an error "global
name 'authenticate' is not defined"
So, I used
*user = EmailOrUsernameModelBackend.authenticate(username=username,
password=password)*
*
*
It shows
TypeError at /authentication/
unbound method authenticate() must be called with EmailOrUsernameModelBackend
instance as first argument (got nothing instead)
Can anyone help me out in solving the issue?
Thanks.

Re: User authentication with either username or email.
As you can see in the views.py I did import the class * EmailOrUsernameModelBackend.* * * Now when I used " *user = EmailOrUsernameModelBackend().authenticate(username=username, password=password) *" It gave an error saying: AttributeError at /tangle/auth/ 'User' object has no attribute 'backend' -- You received this message because you are subscribed to the Google Groups "Django users" group.

Importing the user.id in form.
Hi,
I defined a model which has a 'ForeignKey' to the 'User' .
models.py :
*class Design(models.Model):*
* title = models.CharField(max_length=100)*
* designer=models.ForeignKey(User)
*
* description = models.TextField(null = True)*
* def __unicode__(self):*
* return self.title*
*
*
forms.py :
*class UploadForm(forms.ModelForm): *
*class Meta:*
*model = Design*
*fields = ('title','description')*
*
*
views.py :
*def me(request):*
*if request.POST:*
*form = UploadForm(request.POST, request.FILES)*
*if form.is_valid():*
*form.save()*
*return HttpResponseRedirect('/home/')*
*else:*
*return render_to_response('home/invalid.html')*
*else:*
*form = UploadForm()*
*args = {}*
*args.update(csrf(request))*
*args['form'] = form*
*return render_to_response('home/upload.html',
args,context_instance=RequestContext(request))*
*
*
Now when I save the save the form, the '*designer=models.ForeignKey(User)'
*raises
an error "Column 'designer_id' cannot be null" .
A user after logging in can upload a new design.
How to store the " designer_id " i.e, the user.id of the user who uploaded
the design?
Can someone help me!!
