Advance-Serializers

Done

1. Work with nested searilizer
2. Work with nested selrilizer
3. Serializer Inheritance

• Basic Inheritance

4. Custom to_representation and to_internal_value Method
5. Field-Level Custom Validation
6. Serializer Relations
7. Using SerializerMethodField
8. Integrating Serializers with ViewSets and QuerySets

• Use multiple serializers for different actions:

class ProductViewSet(viewsets.ModelViewSet):
    queryset = Product.objects.all()

    def get_serializer_class(self):
        if self.action == 'list':
            return ListProductSerializer
        if self.action == 'retrieve':
            return DetailedProductSerializer
        return DefaultProductSerializer

Pending

5. Custom create and update Methods

6. Dynamic Fields Serializer

7. Serializer-Level Validation Use specific fields for relationships:

• PrimaryKeyRelatedField
• SlugRelatedField
• HyperlinkedRelatedField
• StringRelatedField

11. Polymorphic Serializers Leverage libraries like django-rest-framework-json-schema or drf-flex-fields for JSON schema validation and dynamic field selection.
12. Custom Fields

• Create custom fields for non-standard data types or formats.

class CommaSeparatedListField(serializers.Field):
    def to_representation(self, value):
        return ",".join(value)

    def to_internal_value(self, data):
        return data.split(",")

class CustomSerializer(serializers.Serializer):
    tags = CommaSeparatedListField()

13. Output Formats (JSON, XML, etc.)

• Customize output by overriding renderers in the view.

from rest_framework.renderers import JSONRenderer, XMLRenderer

class CustomViewSet(viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer
    renderer_classes = [JSONRenderer, XMLRenderer]
