Answer a question

While I am calling Django url in ajax, getting below error

AssertionError: .accepted_renderer not set on Response.

This is my code:

function download(){

    $.ajax({
        url: "/mdm/exam_app/get_assessment_count/",
        dataType: 'json',
        data:{
        },
        type:'GET',
        success: function (data) {
          alert("inside the success method");
    },
        error: function(){
          console.log("error");
          }        
      });
}

If you're using a function based view, then this issue usually means you forgot to add the @api_view and the @renderer_classes decorator to your view.

Example:

from rest_framework.decorators import api_view, renderer_classes
from rest_framework.renderers import JSONRenderer, TemplateHTMLRenderer

@api_view(('GET',))
@renderer_classes((TemplateHTMLRenderer, JSONRenderer))
def get_assessment_count(request):
    [...]
    data = {'count': queryset.count()}
    return Response(data, template_name='assessments.html')
