Django Authentication and Login Issue with Class Based Views - django

Question

I am trying to achieve two different views: one for registration purpose and one for login purpose.
Now, the registration process works perfectly but the authentication process does not.
Here's the code:
in forms.py the first form called UserForm is used to sign up users, the second form called LoginForm is used to log in users.
from django.contrib.auth.models import User
from django import forms
class UserForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput)
class Meta:
model = User
fields = ['first_name', 'last_name', 'username', 'email', 'password']
class LoginForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput)
class Meta:
model = User
fields = ['username', 'email', 'password']
in views.py
from django.shortcuts import render, get_object_or_404, redirect
from .models import Step, Cycle, Program, MotorSetting, GeneralSetting
from django.views import generic
from django.views.generic.edit import CreateView, UpdateView, DeleteView
from django.core.urlresolvers import reverse_lazy
from django.contrib.auth import authenticate, login
from django.views.generic import View
from .forms import UserForm
from .forms import LoginForm
class UserFormView(View):
form_class = UserForm
template_name = 'programs/registration_form.html'
# display blank form
def get(self, request):
form = self.form_class(None)
return render(request, self.template_name, {'form': form})
#process form data
def post(self, request):
form = self.form_class(request.POST)
if form.is_valid():
#storing the data but NOT SAVING them to db yet
user = form.save(commit=False)
#cleaning and normalizing data
username = form.cleaned_data['username']
password = form.cleaned_data['password']
user.set_password(password)
#saving to db
user.save()
#if credentials are correct, this returns a user object
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
return redirect('programs:index')
return render(request, self.template_name, {'form': form})
class LoginFormView(View):
form_class = LoginForm
template_name = 'programs/login_form.html'
# display blank form
def get(self, request):
form = self.form_class(None)
return render(request, self.template_name, {'form': form})
#process form data
def post(self, request):
form = self.form_class(request.POST)
if form.is_valid():
#storing the data but NOT SAVING them to db yet
user = form.save(commit=False)
#if credentials are correct, this returns a user object
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
return redirect('programs:index')
return render(request, self.template_name, {'form': form})
in app/urls.py
from django.conf.urls import include, url
from . import views
app_name = 'programs'
urlpatterns = [
#register page
url(r'^register/$', views.UserFormView.as_view(), name='register'),
#login page
url(r'^login/$', views.LoginFormView.as_view(), name='login'),
]
The registration process goes smoothly, the authentication/login does not. When I fill in the form to login and press send, nothing happens apart from the form getting blank again.
Is there any error I'm not seeing in the code?
Many thanks!
