Django Keycloak Auth is a simple library that authorizes your application's resources using Django Rest Framework.
This package is used to perform authorization by keycloak roles from JWT token. Both realm roles and client roles are supported.
For example, the following token indicates that the user has the realm role "manager" and the client roles "director" and "employer" :
...
"realm_access": {
"roles": [
"manager"
]
},
"resource_access": {
"first-api": {
"roles": [
"director",
"employer",
]
}
},
...

- In settings.py add following Middleware bellow:
MIDDLEWARE = [
#...
'django-keycloak-auth.middleware.KeycloakMiddleware',
#...
]
#...
# Exempt URIS
# For example: ['core/banks', 'swagger']
KEYCLOAK_EXEMPT_URIS = []

'KEYCLOAK_REALM': 'TESTE',

}This is an example how to apply on your Views
from rest_framework import viewsets, views
from . import models, serializers
from rest_framework import status
from django.http.response import JsonResponse
from rest_framework.exceptions import PermissionDenied
class BankViewSet(viewsets.ModelViewSet):
"""
Bank endpoint
This endpoint has all configured keycloak roles
"""
serializer_class = serializers.BankSerializer
queryset = models.Bank.objects.all()
keycloak_roles = {
'GET': ['director', 'judge', 'employee'],
'POST': ['director', 'judge', ],
'UPDATE': ['director', 'judge', ],
'DELETE': ['director', 'judge', ],
'PATCH': ['director', 'judge', 'employee'],
}
def list(self, request):
"""
Overwrite method
You can especify your rules inside each method
using the variable 'request.roles' that means a
list of roles that came from authenticated token.
See the following example bellow:
"""
# list of token roles
print(request.roles)
# Optional: get userinfo (SUB attribute from JWT)
print(request.userinfo)
return super().list(self, request)class CarViewSet(viewsets.ViewSet):
"""
Car endpoint
This endpoint has not configured keycloak roles.
That means all methods will be allowed to access.
"""
def list(self, request):
return JsonResponse({"detail": "success"}, status=status.HTTP_200_OK)class JudgementView(views.APIView):
"""
Judgement endpoint
This endpoint has configured keycloak roles only GET method.
Other HTTP methods will be allowed.
"""
keycloak_roles = {
'GET': ['judge'],
}
def get(self, request, format=None):
"""
Overwrite method
You can especify your rules inside each method
using the variable 'request.roles' that means a

See the following example bellow:
"""

return super().get(self, request)When you don't put keycloak_roles attribute in the Views that means all methods authorizations will be allowed.
Before everything, you must install VirtualEnv.
# Install venv in root project folder
$ python3 -m venv env && source env/bin/activate
# Install dependences
$ pip install -r requirements.txt
# Run tests
$ python manage.py test
Warning: before you update this package, certifies if you'll change the version in
setup.pyfile.
If you interested contribute to developing this project, it was prepared a tiny tutorial to install the environment before you begin:
# Install venv in root project folder
$ python3 -m venv env && source env/bin/activate
# Update packages for development
$ python -m pip install --upgrade -r requirements-development.txt
# Generate distribuition -> it's on me for while ;)
$ python setup.py sdist
# Checks if the package has no errors
$ twine check dist/*
# Upload package -> it's on me for while ;)
$ twine upload --repository-url https://upload.pypi.org/legacy/ dist/*
If you wanna run keycloak docker container:
- Run following command on terminal:
# in root project folder
$ docker-compose up- Open http://localhost:8080/ in your web browser
