.accepted_renderer not set on response

Explanation of query – .accepted_renderer not set on response

This error occurs when trying to render a response using a view that does not have an accepted_renderer attribute set.
The accepted_renderer attribute is used to determine the appropriate renderer for a specific API view, based on the client’s request or specified format.
The error message is raised when the accepted_renderer attribute is missing or not properly set.

Example

Let’s consider a Django REST Framework viewset that returns data in JSON format:

    
from rest_framework.viewsets import ModelViewSet
from rest_framework.renderers import JSONRenderer
from rest_framework.response import Response

class MyViewSet(ModelViewSet):
    renderer_classes = [JSONRenderer]

    def list(self, request, *args, **kwargs):
        # Retrieve data from the database
        data = MyModel.objects.all()
        
        # Serialize the data
        serialized_data = MyModelSerializer(data, many=True)
        
        # Return the serialized data as a JSON response
        return Response(serialized_data.data)
    
  

In this example, the renderer_classes attribute is set to use the JSONRenderer for rendering the response.
The accepted_renderer attribute is automatically set to the appropriate renderer based on the client’s request or the format specified in the URL.
However, if the accepted_renderer attribute is not set, the error .accepted_renderer not set on response will be raised.
