Django Integration for Oauth2 authentication

Easily integrate OAuth2 authentication into your Django project using Omni-Authify. This guide covers configuration, view creation, URL setup, and handling user authentication, providing a seamless experience for developers.

⚙️ Configure Settings

Add the Omni-Authify settings to your Django project settings to include Facebook, GitHub, Google and/or any other OAuth providers.

Django Views

Learn how to create views to handle Facebook,GitHub,Google login and callback in your Django application.

📝 Prerequisites

Installation: Install Omni-Authify with Django support using the following command:
```
pip install omni-authify[django]
```
Django 4.2 or higher
Omni-Authify installed and configured (see )

🚀 Setting Up Views

Create class based views to handle the login and callback processes.

🔁 views.py

This version leverages the OmniAuthifyDjango helper class for a simpler implementation over function based views!.

from django.http import HttpResponse
from omni_authify.frameworks.django import OmniAuthifyDjango

# ======== Facebook Login ========
def facebook_login(request):
    auth = OmniAuthifyDjango(provider_name='facebook')
    return auth.login(request)

def facebook_callback(request):
    auth = OmniAuthifyDjango(provider_name='facebook')
    user_info = auth.callback(request)
    print(f"User info from Facebook: {user_info}")
    
     # Todo: Authenticate/login the user and save the user_info on your own!
    return HttpResponse(user_info)

# ======== GitHub Login ========
def github_login(request):
    auth = OmniAuthifyDjango(provider_name='github')
    return auth.login(request)

def github_callback(request)
    auth = OmniAuthifyDjango(provider_name='github')
    user_info = auth.callback(request)
    print(f"User info from Github: {user_info}")

     # Todo: Authenticate/login the user and save the user_info on your own!
    return HttpResponse(user_info)

# ======== Google Login ========
def google_login(request):
    auth = OmniAuthifyDjango(provider_name='google')
    return auth.login(request)

def google_callback(request):
    auth = OmniAuthifyDjango(provider_name='google')
    user_info = auth.callback(request)
    print(f"User info from Github: {user_info}")

     # Todo: Authenticate/login the user and save the user_info on your own!
    return HttpResponse(user_info)

# ======== LinkedIn Login ========
def linkedin_login(request):
    auth = OmniAuthifyDjango(provider_name='linkedin')
    return auth.login(request)

def linkedin_callback(request):
    auth = OmniAuthifyDjango(provider_name='linkedin')
    user_info = auth.callback(request)
    print(f"User info from Github: {user_info}")

     # Todo: Authenticate/login the user and save the user_info on your own!
    return HttpResponse(user_info)

🌐 Update URLs

Add the login and callback views to your app's urls.py file:

# urls.py

from django.urls import path
from . import views

urlpatterns = [
    # ======== Facebook Login ========
    path('facebook/login/', views.facebook_login, name='facebook_login'),
    path('facebook/callback/', views.facebook_callback, name='facebook_callback'),

    # ======== GitHub Login ========
    path('github/login/', views.github_login, name='github_login'),
    path('github/callback/', views.github_callback, name='github_callback'),

    # ======== Google Login ========
    path('google/login/', views.google_login, name='google_login'),
    path('google/callback/', views.google_callback, name='google_callback'),
  
    # ======== LinkedIn Login ========
    path('linkedin/login/', views.linkedin_login, name='linkedin_login'),
    path('linkedin/callback/', views.linkedin_callback, name='linkedin_callback')
]

📄 Templates

Create a template to display user information or login options.

home.html

<!-- templates/home.html -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Welcome</title>
</head>
<body>
    <div data-gb-custom-block data-tag="if">

        <h1>Welcome, {{ user_info.name }}!</h1>
        <img src="{{ user_info.picture.data.url }}" alt="Profile Picture">
        <p>Email: {{ user_info.email }}</p>
    

<div data-gb-custom-block data-tag="else"></div>

        <h1>Welcome to Our Site</h1>
        <p>Please log in using one of the options below:</p>
        <a href="

<div data-gb-custom-block data-tag="url" data-0='facebook_login'></div>">Login with Facebook</a><br>
        <a href="<div data-gb-custom-block data-tag="url" data-0='github_login'></div>">Login with GitHub</a>
        <a href="<div data-gb-custom-block data-tag="url" data-0='google_login'></div>">Login with Google</a>
        <a href="<div data-gb-custom-block data-tag="url" data-0='linkedin_login'></div>">Login with LinkedIn</a>
    </div>
</body>
</html>

✅ Best Practices

🔒 Use Environment Variables: Always use environment variables to store important information like client_id and client_secret. This helps keep your credentials safe 🛡️.
🔗 Match Redirect URI: Make sure the redirect_uri is consistent between your Provider App settings and your code to avoid errors 🚫.
⚠️ Error Handling: Ensure all potential errors are handled to provide a smooth user experience 🐞.

Omni-Authify makes adding Oauth2 authentication to your Django app straightforward and secure. Follow these steps and best practices to provide your users with a seamless login experience. 🚀✨
