Question

我已经从Django 1.9.7升级到Django 2.2。

渲染视图时，出现以下错误-

'NoneType' object has no attribute 'render_context'

View - 
@login_required
def query_store_admin(request):
   template_name = "query_store/query_store_overview.html"       ##
   print(template_name)
   return render(request, template_name)

Traceback - 

Environment:

Request Method: GET
Request URL: http://127.0.0.1:8000/query_store/query_store_admin

Django Version: 2.2.6
Python Version: 3.6.8

Traceback:

Exception Type: AttributeError at /query_store/query_store_admin
Exception Value: 'NoneType' object has no attribute 'render_context'

我从网络上尝试了很多东西，但这没有帮助。有人可以让我了解在这里实际需要做什么。

'NoneType'对象没有属性'render_context'
