[Fixed]-Django-rest-swagger nested serializers with readonly fields not rendered properly

Try to use drf_yasg instead, Swagger will generate the documentation for APIs, but it’s not absolutely right!
If you want to correct Swagger documentation, you can do it. You will need to use swagger_auto_schema decorator. Below is the sample code:

from drf_yasg import openapi
from drf_yasg.utils import swagger_auto_schema

class ProductSuspendView(CreateAPIView):

    @swagger_auto_schema(
        tags=['dashboard'],
        request_body=openapi.Schema(
            type=openapi.TYPE_OBJECT,
            properties={
                'id': openapi.Schema(
                    type=openapi.TYPE_INTEGER,
                    description='Id',
                ),
                'suspend_kinds': openapi.Schema(
                    type=openapi.TYPE_ARRAY,
                    items=openapi.Items(type=openapi.TYPE_INTEGER),
                    description='Array suspend (Inappropriate image: 1, Insufficient information: 2,  Bad language: 3) (suspend_kinds=[1,2])'
                ),
            }
        ),
        responses={
            status.HTTP_200_OK: SuccessResponseSerializer,
            status.HTTP_400_BAD_REQUEST: ErrorResponseSerializer
        }
    )
    def post(self, request, *args, **kwargs):
        """
        Suspend a product.
        """
        ...
        if success:
            return Response({'success': True}, status.HTTP_200_OK)

        return Response({'success': False}, status.HTTP_400_BAD_REQUEST)

Using https://drf-spectacular.readthedocs.io/en/latest/ would be the right choice for this use case now. this is well maintained and support OpenAPI 3.0+. also it is now suggested by django-rest-framework itself.

1. of everything please use drf-yasg for documentation .

2. you can find its implementation in one of my repository Kirpi and learn how to use that.

3. if you in 3. ; have question,let me know.
