How To Build Login System With Django

Updated: Dec 8, 2022

Hello Everyone !!

This article is about signup and login systems. In this article I will show you how to allow signup, login and logout functionality on a site using the Django framework. Nowadays every website requires users to create accounts. If you know how to build a basic login system and login system template, you can later apply in each online app with some changes to construct web apps quickly.

Now Let's Create loginsin System with Dajngo

Before we begin, First Create the folder and set the path using command prompt. After setting the path, create a virtual environment in that folder.

To create a virtual environment just run the following command on command prompt.

python -m venv venv

Activate virtual environment


Then install Django in that environment

pip install django

Here in my case I have already created an environment and installed django in it.

Now here I am creating django project using the simple command

django-admin startproject registration

After running the above command registration folder will create in the main project folder ( Django login and signup ) as shown in the below screenshot.

Then again set the path Django login and signup > registration by running this command cd folder_name and after that run the following command on command prompt.

python startapp users

After running the above command one more folder will be created in the registration folder.

Now open the file from the registration folder and register the users in installed apps as shown in the screenshot.

Now create the folders in the users folder again one more folder in template which name is user. In this folder all user related html files are stored here


Django signup and login>registration>users>templates>user

Here I have already created html files for our login system as shown in the below screenshot.

Now we have to create a view for different pages like home page, login page, signup page, profile view page, password reset page, change password view etc.

Django login and signup>registration>users>

from django.shortcuts import render, redirect
from django.urls import reverse_lazy
from django.contrib.auth.views import LoginView, PasswordResetView, PasswordChangeView
from django.contrib import messages
from django.contrib.messages.views import SuccessMessageMixin
from django.views import View
from django.contrib.auth.decorators import login_required

from .forms import RegisterForm, LoginForm, UpdateUserForm, UpdateProfileForm

def home(request):
    return render(request, 'users/home.html')

class RegisterView(View):
    form_class = RegisterForm
    initial = {'key': 'value'}
    template_name = 'users/register.html'

    def dispatch(self, request, *args, **kwargs):
        # will redirect to the home page if a user tries to access the register page while logged in
        if request.user.is_authenticated:
            return redirect(to='/')

        # else process dispatch as it otherwise normally would
        return super(RegisterView, self).dispatch(request, *args, **kwargs)

    def get(self, request, *args, **kwargs):
        form = self.form_class(initial=self.initial)
        return render(request, self.template_name, {'form': form})

    def post(self, request, *args, **kwargs):
        form = self.form_class(request.POST)

        if form.is_valid():

            username = form.cleaned_data.get('username')
            messages.success(request, f'Account created for {username}')

            return redirect(to='login')

        return render(request, self.template_name, {'form': form})

# Class based view that extends from the built in login view to add a remember me functionality
class CustomLoginView(LoginView):
    form_class = LoginForm

    def form_valid(self, form):
        remember_me = form.cleaned_data.get('remember_me')

        if not remember_me:
            # set session expiry to 0 seconds. So it will automatically close the session after the browser is closed.

            # Set session as modified to force data updates/cookie to be saved.
            self.request.session.modified = True

        # else browser session will be as long as the session cookie time "SESSION_COOKIE_AGE" defined in
        return super(CustomLoginView, self).form_valid(form)

class ResetPasswordView(SuccessMessageMixin, PasswordResetView):
    template_name = 'users/password_reset.html'
    email_template_name = 'users/password_reset_email.html'
    subject_template_name = 'users/password_reset_subject'
    success_message = "We've emailed you instructions for setting your password, " \
                      "if an account exists with the email you entered. You should receive them shortly." \
                      " If you don't receive an email, " \
                      "please make sure you've entered the address you registered with, and check your spam folder."
    success_url = reverse_lazy('users-home')

class ChangePasswordView(SuccessMessageMixin, PasswordChangeView):
    template_name = 'users/change_password.html'
    success_message = "Successfully Changed Your Password"
    success_url = reverse_lazy('users-home')

def profile(request):
    if request.method == 'POST':
        user_form = UpdateUserForm(request.POST, instance=request.user)
        profile_form = UpdateProfileForm(request.POST, request.FILES, instance=request.user.profile)

        if user_form.is_valid() and profile_form.is_valid():
            messages.success(request, 'Your profile is updated successfully')
            return redirect(to='users-profile')
        user_form = UpdateUserForm(instance=request.user)
        profile_form = UpdateProfileForm(instance=request.user.profile)

    return render(request, 'users/profile.html', {'user_form': user_form, 'profile_form': profile_form})

To display the page we need to set the url of the all different page in file for that we create file users folder.

Django login and signup>registration>users>

from django.urls import path
from .views import home, profile, RegisterView

urlpatterns = [
    path('', home, name='users-home'),
    path('register/', RegisterView.as_view(), name='users-register'),
    path('profile/', profile, name='users-profile'),

Django login and signup>registration>

from django.contrib import admin

from django.urls import path, include, re_path

from django.conf import settings
from django.conf.urls.static import static

from django.contrib.auth import views as auth_views
from users.views import CustomLoginView, ResetPasswordView, ChangePasswordView

from users.forms import LoginForm

urlpatterns = [

    path('', include('users.urls')),

    path('login/', CustomLoginView.as_view(redirect_authenticated_user=True, template_name='users/login.html',
                                           authentication_form=LoginForm), name='login'),

    path('logout/', auth_views.LogoutView.as_view(template_name='users/logout.html'), name='logout'),

    path('password-reset/', ResetPasswordView.as_view(), name='password_reset'),



    path('password-change/', ChangePasswordView.as_view(), name='password_change'),

    re_path(r'^oauth/', include('social_django.urls', namespace='social')),

] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Create a forms file in users folder

Django login and signup>registration>users>

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm, AuthenticationForm

from .models import Profile

class RegisterForm(UserCreationForm):
    # fields we want to include and customize in our form
    first_name = forms.CharField(max_length=100,
                                 widget=forms.TextInput(attrs={'placeholder': 'First Name',
                                                               'class': 'form-control',
    last_name = forms.CharField(max_length=100,
                                widget=forms.TextInput(attrs={'placeholder': 'Last Name',

    password1 = forms.CharField(max_length=50,
                                widget=forms.PasswordInput(attrs={'placeholder': 'Password',
                                                                  'class': 'form-control',
                                                                  'data-toggle': 'password',
                                                                  'id': 'password',
    password2 = forms.CharField(max_length=50,
                                widget=forms.PasswordInput(attrs={'placeholder': 'Confirm Password',
                                                                  'class': 'form-control',
                                                                  'data-toggle': 'password',
