Python3.x Django ImportError：无法从django.shortcuts导入名称render_to_response

升级到Django 3.0后，出现以下错误:

ImportError: cannot import name 'render_to_response' from 'django.shortcuts'

我的观点是:

from django.shortcuts import render_to_response

from django.template import RequestContext

def index(request):
    context = {'foo': 'bar'}
    return render_to_response('index.html', context, context_instance=RequestContext(request))

以下是完整的回溯:
