/ context 处的 TypeError 必须是 dict 而不是 RequestContext

Question

我有一个基于 Django 1.9 构建的应用程序，但现在我已将其升级到 2.2。好吧，我遇到了一个奇怪的错误，我无法使用现有的类似解决方案来解决它。在我的例子中，我们从一个不同的文件中获取 templateResponse 然后是内置的[说 x.py]-class TemplateResponse(DefaultResponse):"""A normal response involving data that can be sent to fill in atemplate.  Since the template is specific to HTML responses, whena JSON response is desired, this class is indistinguishablefrom DefaultResponse."""def __init__(self, template, data, status=200):    self.data = data    self.template = template    self.status = status[基础.py]-def home(guts):     return TemplateResponse(template, {'c_sk': c_nt,                                   'd_sk_count': d_sk_count} 回溯错误 -response = get_response(request) …▶ Local vars/home/gaurav/Desktop/a Upgrade Work/a/new_cl/lib/python3.6/site-packages/django/core/handlers/base.py in _get_response                response = self.process_exception_by_middleware(e, request) …    ▶ Local vars /home/gaurav/Desktop/a Upgrade Work/a/new_cl/lib/python3.6/site-packages/django/core/handlers/base.py in _get_response                response = wrapped_callback(request, *callback_args, **callback_kwargs) …    ▶ Local vars/usr/lib/python3.6/contextlib.py in inner                return func(*args, **kwds) …    ▶ Local vars/home/gaurav/Desktop/a Upgrade Work/a/new_cl/lib/python3.6/site-packages/django/contrib/auth/decorators.py in _wrapped_view                return view_func(request, *args, **kwargs) …    ▶ Local vars/home/gaurav/Desktop/a Upgrade Work/a/main/x.py in g            response = seed.sprout(context, format) …    ▶ Local vars/home/gaurav/Desktop/a Upgrade Work/a/main/x.py in sprout            return self.sprout_html(context) …    ▶ Local vars/home/gaurav/Desktop/a Upgrade Work/a/main/x.py in sprout_html        body = self.template.render(context) …    ▶ Local vars

我通过更改下面提到的代码解决了这个问题 -

def home(guts): 

  return TemplateResponse(template.render(mt_context1)) 

但是，这又引入了另一个错误。

不确定我是否可以在这里发布这个问题，但由于它似乎与此有关，我在下面提到它，任何对此的专业人士，我真的可以使用一些建议:)

异常类型：TypeError at / 异常值：init（）缺少1个必需的位置参数：'data'

您应该将传入请求传递给 TemplateResponse

def home(request):
    response = TemplateResponse(request, 'mytemplate.html', {'c_sk': c_nt,'d_sk_count': d_sk_count} )
        return response
