User matching query does not exist using authentication

I've created a user with my following code:

views.py (register view works fine but login view doesn't)

def register(request):  
    if request.method == 'POST':
    form = UserProfileForm(request.POST) 

    if form.is_valid():
        user = form.save()

        username = ... 
        u = User.objects.create_user(username, user.email, user.password)
        u.save()
        ... 

    else:
        return HttpResponse('Nombre o contrasena incorrectos.')
else:
    form = UserProfileForm()

...


def log_in(request):   
if request.method == 'POST':
    form = UserLoginForm(request.POST)
    if form.is_valid():
        email = form.cleaned_data['email']
        password = form.cleaned_data['password']
        try:
            u = User.objects.get(email=email, password=password)
        except User.DoesNotExist:
            return HttpResponse('Email o contrasena incorrectos.')
        ...
else:
    form = UserLoginForm()
...

The register view creates my custom user without any problem, but when I want to use it to login into my app, the login view throws a User.DoesNotExist exception. Why is that?

The issue is here:

u = User.objects.get(email=email, password=password)

It has no sense, you can't compare password field value, because it is not stored raw in database.

To check is user has provided correct password, you shoud use authenticate built-in function:

u = authenticate(username=username, password=password)

You can see solid example here: http://code.runnable.com/UpBfbcg4PNU0AAHG/how-to-check-if-the-user-is-authenticated-in-django-for-python-authentication-and-httprequest

..or in official Django documentation (login function example): https://docs.djangoproject.com/en/1.8/topics/auth/default/#django.contrib.auth.login
