Custom DRF Permissions in Django Rest Framework
In this tutorial, we will learn how to create custom permissions in Django Rest Framework to control access to your API endpoints.
Step 1: Define Custom Permission Class
To create a custom permission class, we need to define a new class that inherits from the rest_framework.permissions.BasePermission class.
“`python
from rest_framework.permissions import BasePermission
class CustomPermission(BasePermission):
def has_permission(self, request, view):
# Custom logic to determine if the request has permission
return True # Return True if the request has permission, False otherwise
“`
Step 2: Apply Custom Permission to View
Once we have defined our custom permission class, we can apply it to a view by setting the permission_classes attribute on the view class.
“`python
from rest_framework.views import APIView
from .permissions import CustomPermission
class CustomView(APIView):
permission_classes = [CustomPermission]
def get(self, request, *args, **kwargs):
# Custom logic for GET request
return Response(“This is a GET request”)
“`
Step 3: Test Custom Permission
Finally, we can test our custom permission by making a request to the view and checking if the permission logic allows or denies access.
“`bash
curl -X GET http://localhost:8000/custom-view/
“`
If the custom permission logic allows access, you should see the response “This is a GET request”. Otherwise, you will receive an HTTP 403 Forbidden error.
Conclusion
By creating custom permissions in Django Rest Framework, you can control access to your API endpoints based on your application’s specific requirements. This allows you to create a more secure and tailored API for your users.
