Django Rest API-Django Rest API for easy API development

Example

class BookSerializer(serializers.ModelSerializer): class Meta: model = Book fields = ['id', 'title', 'author', 'publication_date']

Scenario

Serialization is a key function of DRF that allows you to convert complex data types, such as Django model instances, into native Python data types suitable for rendering as JSON responses. In the example provided, a BookSerializer class is defined to serialize Book model instances into JSON format, including specific fields.

Example

class BookViewSet(viewsets.ModelViewSet): queryset = Book.objects.all() serializer_class = BookSerializer

Scenario

DRF provides powerful class-based views and viewsets that handle common CRUD operations out of the box. In the example, a BookViewSet class is defined, which inherits from ModelViewSet to automatically provide CRUD functionality for the Book model. This eliminates the need to write repetitive view code for each CRUD operation.

Example

class IsOwnerOrReadOnly(permissions.BasePermission): def has_object_permission(self, request, view, obj): if request.method in permissions.SAFE_METHODS: return True return obj.owner == request.user

Scenario

DRF offers robust authentication and permission systems to secure your APIs. Custom permissions can be defined to control access to specific resources based on user roles or other criteria. In the example, a custom permission class IsOwnerOrReadOnly is created to allow read-only access to objects for non-owners while restricting write access to the owner.
