# The Complete Django Authentication System This is the `final step` in making a basic `Authentication system` or `App` in Django. There are many other concepts that we will cover in our further tutorials. So in our previous [section](https://blog.teachmebro.com/building-admin-dashboard-using-django-admin), we have successfully added models to admin and access them via the **Admin interface**. Let's quickly add the `Login` and `Logout` features in our Django app and complete our system.  Login ----- Let's add `login` functionality first, you will notice that it is very easy to add login feature than signup feature and logout is very easy if we are using Django's built-in the authentication system, which we are using. Open the `social/urls.py` file: import the below package on the top of the file ``` from django.contrib.auth import views as auth_views ``` and now add the below URL in the `urlpatterns` list, ``` urlpatterns = [ path('admin/', admin.site.urls), url(r"^$", acccount_views.IndexView.as_view(), name="index"), url(r"^signup/$", acccount_views.signup, name="signup"), #login url goes here url(r'^login/$', auth_views.LoginView.as_view(),{'template_name': 'core/login.html'}, name='login'), ] ``` Now in the `account/templates/registration/` folder create a `login.html `file and paste the below code in it: ``` LOGIN

LOGIN

{% csrf_token %} {{form.as_p}}

``` Logout ------ To implement logout just add the below URL into the `social/urls.py`: ``` url(r'^logout/$', auth_views.LogoutView.as_view(),{'template_name': 'core/logout.html'}, name='logout'), ``` After Adding The Above Line in `social/urls.py`: ``` urlpatterns = [ path('admin/', admin.site.urls), url(r"^$", acccount_views.IndexView.as_view(), name="index"), url(r"^signup/$", acccount_views.signup, name="signup"), url(r'^login/$', auth_views.LoginView.as_view(),{'template_name': 'core/login.html'}, name='login'), #this url here url(r'^logout/$', auth_views.LogoutView.as_view(),{'template_name': 'core/logout.html'}, name='logout'), ] ``` Now in the `account/templates/registration/` folder create a `logout.html `file and paste the below code in it: ``` Logout

Logout Successfully

``` and also in the `index.html` add this line inside it: ```

Logout

``` ```

Please login here

Login Now!

``` now your `index.html` should look like this:  ``` Home {% if user.is_authenticated %}

Welcome, {{user.username}} You Successfully Logged In

Logout

{% else %}

Please login here

Login Now!

Signup

{% endif %} ``` `That's it! Congratulations you have successfully implemented an Authentication System or App in Django.` You can find the project repository link here at [TeachMeBro--Social-App](https://github.com/altafshaikh/TeachMeBro--Social-App) for this tutorial. The complete `Social Media Web Application` is very large. It is difficult to teach in one single go. So we will cover the more **advanced ** concept step by step in our further tutorials. You can get the `Full Source code` of the **Friends-Social Media** app [here](https://github.com/altafshaikh/Friends-The-Social-Network) and you can directly learn from their by referring the project or you can also contribute to that project if you wish to. Thank You So Much and stay tuned with us for more cool tutorials and projects : ) ### Learn how to build Social Media Website In Django Full Tutorial Video available here, %[https://www.youtube.com/playlist?list=PLMoaiG_x8uS5Fi7oE67Z5ej-mPuJb8WnK] Project Demo ------------ %[https://youtu.be/wipqpB8lnRs] `Keep Learning, Keep Growing :D`
