DRF Authentication & Permissions

🐍 DjangoLesson 12Advanced

DRF provides pluggable authentication schemes (Token, Session, JWT) and granular permissions checking access rules for API endpoints.

1 Implementing Permissions

Python — permissions.py

from rest_framework import permissions

class IsAuthorOrReadOnly(permissions.BasePermission):
    def has_object_permission(self, request, view, obj):
        # Read permissions are allowed to any request
        if request.method in permissions.SAFE_METHODS:
            return True
        # Write permissions are only allowed to the author of the post
        return obj.author == request.user

# Apply inside ViewSet
# permission_classes = [permissions.IsAuthenticatedOrReadOnly, IsAuthorOrReadOnly]
