🚀 Quick Start

Installation

pip install drf-spectacular-auth

Or get the latest version:

pip install --upgrade drf-spectacular-auth

Basic Setup

1. Add to your Django settings:

INSTALLED_APPS = [
    'drf_spectacular_auth',  # Add 'drf_spectacular_auth' before 'drf_spectacular'
    'drf_spectacular',
    # ... your other apps
]

# Optional: Add authentication backend for better integration
AUTHENTICATION_BACKENDS = [
    'drf_spectacular_auth.backend.SpectacularAuthBackend',
    'django.contrib.auth.backends.ModelBackend',  # Keep default backend
]

# Optional: Add middleware for automatic authentication
MIDDLEWARE = [
    # ... your existing middleware
    'drf_spectacular_auth.middleware.SpectacularAuthMiddleware',
    # ... rest of your middleware
]

DRF_SPECTACULAR_AUTH = {
    'COGNITO_REGION': 'your-aws-region',
    'COGNITO_CLIENT_ID': 'your-cognito-client-id',
    'COGNITO_CLIENT_SECRET': 'your-client-secret',  # Private client인 경우에만 필요
    
    # Optional: User management settings
    'AUTO_CREATE_USERS': True,  # Auto-create users from Cognito
    'REQUIRE_AUTHENTICATION': False,  # Require auth to access Swagger UI
}

2. Update your URLs:

from drf_spectacular_auth.views import SpectacularAuthSwaggerView

urlpatterns = [
    path('api/auth/', include('drf_spectacular_auth.urls')),  # Authentication endpoints
    path('api/docs/', SpectacularAuthSwaggerView.as_view(url_name='schema'), name='swagger-ui'),
    # ... your other urls
]

3. That's it! 🎉 Your Swagger UI now has an authentication panel.

🏗️ Architecture

Integration Strategies

This package offers multiple integration strategies to suit different use cases:

1. Simple Auth Panel (Default)

• Adds authentication panel to Swagger UI
• Minimal configuration required
• Good for basic documentation with optional authentication

2. HttpOnly Cookie Integration (Recommended)

• Secure HttpOnly cookie-based token storage
• XSS attack protection
• Automatic authentication handling
• CSRF protection with SameSite cookies

3. Middleware Integration

• Session-based auth persistence
• Better integration with existing Django auth

4. Backend Integration (Advanced)

• Full Django user integration
• Auto-create users from Cognito
• Supports existing Django permission systems

Comparison with django-auth-adfs

Unlike django-auth-adfs which focuses on ADFS/Azure AD integration, this package:

• Specializes in AWS Cognito authentication
• Focuses on API documentation (Swagger UI) integration
• Offers lighter-weight integration options
• Supports both simple overlay and full Django auth integration

⚙️ Configuration

AWS Cognito Client Types

Public Client (Basic):

• Not Client Secret
• COGNITO_CLIENT_SECRET=None

Private Client (Enhanced):

• Need Client Secret
• Must have COGNITO_CLIENT_SECRET
• Automatic calculate SECRET_HASH

# Public Client (Basic)
DRF_SPECTACULAR_AUTH = {
    'COGNITO_REGION': 'ap-northeast-2',
    'COGNITO_CLIENT_ID': 'your-public-client-id',
}

# Private Client (Enhanced)
DRF_SPECTACULAR_AUTH = {
    'COGNITO_REGION': 'ap-northeast-2',
    'COGNITO_CLIENT_ID': 'your-private-client-id',
    'COGNITO_CLIENT_SECRET': os.getenv('COGNITO_CLIENT_SECRET'),

🎨 Customization

Custom Authentication Provider

from drf_spectacular_auth.providers.base import AuthProvider

class CustomAuthProvider(AuthProvider):
    def authenticate(self, credentials):
        # Your custom authentication logic
        return {
            'access_token': 'your-token',
            'user': {'email': '[e-mail]'}
        }
    
    def get_user_info(self, token):
        # Get user information from token
        return {'email': '[e-mail]'}

# Register your provider
DRF_SPECTACULAR_AUTH = {
    'CUSTOM_AUTH_PROVIDERS': [
        'path.to.your.CustomAuthProvider'
    ]
}

Custom Security Schemes

The package automatically detects your OpenAPI security schemes and supports custom names:

# drf-spectacular settings
SPECTACULAR_SETTINGS = {
    "APPEND_COMPONENTS": {
        "securitySchemes": {
            "CognitoJWT": {
                "type": "http",
                "scheme": "bearer", 
                "bearerFormat": "JWT",
                "description": "AWS Cognito JWT authentication",
            }
        },
    },
    "SECURITY": [{"CognitoJWT": []}],
}

# Or using OpenApiAuthenticationExtension
class CognitoJWTAuthenticationScheme(OpenApiAuthenticationExtension):
    target_class = "your_app.authentication.CognitoJWTAuthentication"
    name = "CognitoJWT"

    def get_security_definition(self, auto_schema):
        return {
            "type": "http",
            "scheme": "bearer",
            "bearerFormat": "JWT", 
            "description": "AWS Cognito JWT authentication",
        }

Supported scheme names: CognitoJWT, BearerAuth, Bearer, JWT, ApiKeyAuth, TokenAuth, and any custom name defined in your OpenAPI spec.

Custom Templates

DRF_SPECTACULAR_AUTH = {
    'CUSTOM_TEMPLATES': {
        'auth_panel': 'your_app/custom_auth_panel.html',
        'login_form': 'your_app/custom_login_form.html',
    }
}

🐛 Troubleshooting

Common Issues

Q: I see unwanted topbar in my Swagger UI
A: Update to v1.2.0+ which fixes the template inheritance issue.

Q: Authentication panel is not showing
A: Make sure you're using SpectacularAuthSwaggerView instead of the default Swagger view.

Q: Token not being auto-authorized in Swagger
A: Verify that AUTO_AUTHORIZE: True is set in your settings and check browser console for errors. The system automatically detects your security scheme name from the OpenAPI spec, supporting custom names like CognitoJWT, Bearer, etc.

Q: AWS Cognito authentication fails
A: Check your Cognito configuration:

• Verify COGNITO_REGION, COGNITO_CLIENT_ID are correct
• For private clients, ensure COGNITO_CLIENT_SECRET is set
• Check AWS Cognito logs for detailed error messages

Q: Template loading errors
A: Ensure drf_spectacular_auth is added to INSTALLED_APPS before drf_spectacular.

Migration from Previous Versions

From v1.1.x to v1.2.0:

• No breaking changes - just update your package
• Topbar issues will be automatically resolved
• Remove any custom workarounds for template conflicts
