问题描述

当我在ajax中调用Django url时，出现以下错误

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

AssertionError:未在Response上设置.accepted_renderer.

AssertionError: .accepted_renderer not set on Response.

这是我的代码:

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");
          }        
      });
}

推荐答案

如果您使用的是基于函数的视图，那么此问题通常意味着您忘记添加

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.

示例:

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')
