Social-app-django is a Django app that provides social authentication integration for Django projects. It's part of the python-social-auth ecosystem and allows developers to easily add social login functionality to their Django applications using various social platforms like Facebook, Google, Twitter, and more.

Pros

• Easy integration with Django projects
• Supports a wide range of social authentication providers
• Customizable and extensible
• Active community and regular updates

Cons

• Can be complex to set up for beginners
• Documentation could be more comprehensive
• Requires additional configuration for each social provider
• May introduce security risks if not properly implemented

Code Examples

1. Basic configuration in settings.py:

INSTALLED_APPS = [
    # ...
    'social_django',
]

AUTHENTICATION_BACKENDS = [
    'social_core.backends.google.GoogleOAuth2',
    'social_core.backends.facebook.FacebookOAuth2',
    'django.contrib.auth.backends.ModelBackend',
]

2. URL configuration in urls.py:

from django.urls import path, include

urlpatterns = [
    # ...
    path('social-auth/', include('social_django.urls', namespace='social')),
]

3. Template example for login buttons:

<a href="{% url 'social:begin' 'google-oauth2' %}">Login with Google</a>
<a href="{% url 'social:begin' 'facebook' %}">Login with Facebook</a>

4. Accessing user data in a view:

from django.contrib.auth.decorators import login_required

@login_required
def profile(request):
    user = request.user
    social_account = user.social_auth.get(provider='google-oauth2')
    extra_data = social_account.extra_data
    return render(request, 'profile.html', {'extra_data': extra_data})

Getting Started

1. Install the package:

   pip install social-auth-app-django
   

2. Add 'social_django' to INSTALLED_APPS in settings.py

3. Add social auth backends to AUTHENTICATION_BACKENDS in settings.py

4. Include social_django URLs in your project's urls.py

5. Configure social auth settings for your chosen providers (e.g., SOCIAL_AUTH_GOOGLE_OAUTH2_KEY, SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET)

6. Run migrations:

   python manage.py migrate
   

7. Add social login buttons to your templates and start using social authentication in your Django project.
