Enhance OpenID Connect Functionality

January 25, 2024

In today’s digital era, OpenID Connect (OIDC) has emerged as a popular authentication protocol for enabling secure user authentication across different platforms. By integrating DjangoCMS OIDC Form Fields with Aldryn Forms, you can enhance your OIDC capabilities and streamline user authentication in your Django projects. In this article, we will explore the powerful features of DjangoCMS OIDC Form Fields and demonstrate how to integrate them with Aldryn Forms.

Installation

To get started, install the djangocms-oidc-form-fields package using pip:

#shell
$ pip install djangocms-oidc-form-fields

Next, add the aldryn_forms and djangocms_oidc_form_fields plugins to your Django project’s INSTALLED_APPS in the settings.py file:

#python
INSTALLED_APPS = [
    # ...
    'multiselectfield',
    'django_countries',
    'mozilla_django_oidc',
    'djangocms_oidc',
    'aldryn_forms',
    'djangocms_oidc_form_fields',
]

Configure the OIDC authentication backend and middleware:

#python
AUTHENTICATION_BACKENDS = [
    # ...
    'djangocms_oidc.auth.DjangocmsOIDCAuthenticationBackend',
]

MIDDLEWARE = [
    # ...
    'djangocms_oidc.middleware.OIDCSessionRefresh',
]

Define the OIDC classes and endpoints in your settings.py file:

#python
OIDC_AUTHENTICATE_CLASS = "djangocms_oidc.views.DjangocmsOIDCAuthenticationRequestView"
OIDC_CALLBACK_CLASS = "djangocms_oidc.views.DjangocmsOIDCAuthenticationCallbackView"
OIDC_OP_AUTHORIZATION_ENDPOINT = "https://example.com/authorization-endpoint"
OIDC_RP_CLIENT_ID = "myClientId"

Update your project’s urls.py to include the OIDC and OIDC Form Fields URLs:

#python
urlpatterns = [
    # ...
    path('oidc/', include('mozilla_django_oidc.urls')),
    path('djangocms-oidc/', include('djangocms_oidc.urls')),
]

Usage in Administration

Once the installation and setup are complete, you can easily access the OIDC Form Field plugins in the Django administration interface. The following OIDC Field plugins are available:

OIDC Fields
OIDC Text
OIDC Textarea
OIDC Hidden
OIDC Email
OIDC EmailIntoFromField
OIDC Phone
OIDC Number
OIDC Boolean

These plugins provide a range of options for capturing and processing OIDC-related data in your forms.

Example Implementations

1. Integration with Docker

To run an example of DjangoCMS OIDC Form Fields in a Docker container, follow these steps:

Clone the djangocms-oidc-form-fields repository:

#shell
$ git clone https://github.com/CZ-NIC/djangocms-oidc-form-fields.git

Navigate to the example directory:

#shell
$ cd djangocms-oidc-form-fields/example

Build the Docker image:

#shell
$ docker-compose build web

Run database migrations:

#shell
$ docker-compose run --user $(id -u):$(id -g) web python manage.py migrate

Load sample data:

#shell
$ docker-compose run --user $(id -u):$(id -g) web python manage.py loaddata site.json

Start the webserver:

#shell
$ docker-compose up -d

Access the application in your browser at https://localhost:8000/.

2. Integration with MongoDB

DjangoCMS OIDC Form Fields can be seamlessly integrated with MongoDB by using the django-mongodb-engine package. Follow these steps to integrate MongoDB as the backend database:

Install the django-mongodb-engine package:

#shell
$ pip install django-mongodb-engine

Configure the MongoDB database settings in your Django project’s settings.py file:

#python
DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'your-database-name',
    }
}

Migrate the database:

#shell
$ python manage.py migrate

With MongoDB as the backend database, you can leverage its scalability and flexibility for handling large amounts of OIDC-related data.

3. Integration with FastAPI

If you’re building a modern, high-performance web API using FastAPI, you can easily integrate DjangoCMS OIDC Form Fields to handle OIDC authentication. Follow these steps to integrate FastAPI with DjangoCMS OIDC Form Fields:

Install djangorestframework and fastapi packages:

#shell
$ pip install djangorestframework fastapi

Create a FastAPI app and configure the OIDC authentication backend:

#python
from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware
from djangocms_oidc.auth import DjangocmsOIDCAuthenticationBackend

app = FastAPI()

app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_methods=["*"],
    allow_headers=["*"],
)

authentication_backend = DjangocmsOIDCAuthenticationBackend()
app.add_middleware(
    OIDCAuthenticationMiddleware,
    backend=authentication_backend,
)

@app.get("/")
async def root():
    return {"message": "Welcome to FastAPI with DjangoCMS OIDC Form Fields!"}

Run the FastAPI app:

#shell
$ uvicorn main:app --reload

With FastAPI and DjangoCMS OIDC Form Fields, you can build highly scalable and secure APIs that leverage the power of OIDC authentication.
