A Django Blog In VS Code — Authentications, Login & Logout

How To Create A Blog in VS Code — Part V— DjangoSeries Episode # 08

Hi, in this post we’re going to be learning how to create an authentication system for our Django application so that users can log in log out.

Let’s go ahead and get started!

00#Step — This is a continuation of this post;

In the previous episode we saw how to create this registration page where users could create new accounts but they’re not able to log:

Our registration page created at the previous #DjangoSeries episode #07.

Admin dashboard is only for users with admin access privilege.

By default our new users aren’t going to have that so we need to have a login page for them on the front end.

Let’s get started by using Django default login views.

01#Step — GoTo django_project/urls.py and add:

from django.contrib import admin
from django.contrib.auth import views as auth_views
from django.urls import path, include
from users_hub import views as user_views
urlpatterns = [path('admin/', admin.site.urls),
path('register/', user_views.register, name='register'),
path('login/', auth_views.LoginView.as_view(template_name="users_hub/login.html"), name='login'),
path('logout/', auth_views.LogoutView.as_view(
template_name="users_hub/logout.html"), name='logout'),
path('', include('blog.urls')),

02#Step — If you try to access /login page by running the server you will receive this error:

python manage.py runserver
there is no users_hub/login.html :/ Oops!...I Did It Again :)

It will try to upload a template at users_hub/login.html, which we didn’t create yet…

03#Step —Create a login.html template inside:


04#Step — Create a users_hub/logout.html

05#Step — Create a users_hub/profile.html

06#Step — GoTo django_project/Settings.py and at the very end, add:

....# Crisp configCRISPY_TEMPLATE_PACK = 'bootstrap4'# Redirecting to home
LOGIN_REDIRECT_URL = 'blog-home'
LOGIN_URL = 'login'

07#Step — Modify users_hub/views.py to:

from django.shortcuts import render, redirect
from django.contrib import messages
from users_hub.forms import UserRegisterForm
from django.contrib.auth.decorators import login_required
def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
messages.success(request, f'Hi {username}! Your account has been created! Now login!')
return redirect('login')
form = UserRegisterForm()
return render(request, 'users_hub/register.html', {'form': form})
def profile(request):
return render(request, 'users_hub/profile.html')

After the user have successfully registered it would make a lot more sense right here to redirect them to the login page, right?

08#Step — Now Let’s try to register userTest3:

And there you have it! 👍

09#Step — GoTo django_project\blog\templates\blog\base.html

Open up our base template that contains the navigation and then put in a conditional that checks whether the user is logged in or logged out:

   <li class="nav-item">
<a class="nav-link active" aria-current="page" href="{% url 'blog-home' %}">Home</a>
<li class="nav-item">
<a class="nav-link" href="{% url 'about-page' %}">About</a> </li>
{% if user.is_authenticated %}

<li class="nav-item">
<a class="nav-link" href="{% url 'logout' %}">Logout</a>
<li class="nav-item">
<a class="nav-link" href="{% url 'profile' %}">Profile</a>
{% else %}
<li class="nav-item">
<a class="nav-link" href="{% url 'login' %}">Login</a>
<li class="nav-item">
<a class="nav-link" href="{% url 'register' %}">Register</a>
{% endif %}
{% if user.is_authenticated %}
<li class="nav-item">
<a class="nav-link" href="{% url 'profile' %}">Hi,{{ user }}!</a>
{% endif %}

10#Step — Access login route:

11#Step — Create a users_hub/register.html

12#Step — Modify your blog/base.html template:

Notice each of the modifications in the method links 👆

13#Step — Here is your final django_project/urls.html template:

That’s all Folks!

In the next #DjangoSeries Episode we will continue to customize registration in Django with Upload Profile Image.

See you around. Bye!
