Django错误:render_to_response()得到了一个意外的关键字参数'context_instance'

Question

升级到Django 1.10后,我收到错误render_to_response() got an unexpected keyword argument 'context_instance'.

我的观点如下:

from django.shortcuts import render_to_response
from django.template import RequestContext

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

这是完整的追溯:

Traceback:

File "/Users/alasdair/.virtualenvs/django110/lib/python2.7/site-packages/django/core/handlers/exception.py" in inner
  39.             response = get_response(request)

File "/Users/alasdair/.virtualenvs/django110/lib/python2.7/site-packages/django/core/handlers/base.py" in _get_response
  187.                 response = self.process_exception_by_middleware(e, request)

File "/Users/alasdair/dev/rtr/rtr/urls.py" in my_view
  26.     return render_to_response('my_template.html', context,  context_instance=RequestContext(request))

 Exception Type: TypeError at /
Exception Value: render_to_response() got an unexpected keyword argument 'context_instance'

Answer 1

该context_instance参数render_to_response是不推荐在Django 1.8,并且在Django 1.10删除.

解决方案是切换到render自动使用a 的快捷方式RequestContext.

更新导入和视图,如下所示.请注意,render将request对象作为其第一个参数.

from django.shortcuts import render

def my_view(request):
    context = {'foo': 'bar'}
    return render(request, 'my_template.html', context)

该render快捷方式是在Django 1.3中引入的,因此这个更改与旧版本的Django兼容.
