问题描述
我正在尝试通过这种方式进行操作,但这是行不通的.
I'm trying to do it this way, but it doesn't work.
class MyView(View):
def options(self, request, *args, **kwargs):
"""
Handles responding to requests for the OPTIONS HTTP verb.
"""
response = http.HttpResponse()
if self.kwargs.has_key('xml'):
response['Content-Type'] = 'text/xml; charset=utf-8'
return response
推荐答案
我认为关键点是django.views.generic.base
中的render_to_response
,其代码是这样的:
I think the key point is render_to_response
in django.views.generic.base
, whose code is this:
def render_to_response(self, context, **response_kwargs):
"""
Returns a response, using the `response_class` for this
view, with a template rendered with the given context.
If any keyword arguments are provided, they will be
passed to the constructor of the response class.
"""
response_kwargs.setdefault('content_type', self.content_type) # key
return self.response_class(
request=self.request,
template=self.get_template_names(),
context=context,
**response_kwargs
)
对于您的情况,可能需要以下代码:
As for your case, May be you need this code:
class MyView(ListView):
def get(self, request, *args, **kwargs):
context = self.get_context_data()
if self.kwargs.has_key('xml'):
return self.render_to_response(context, content_type="text/xml; charset=utf-8")
return self.render_to_response(context)
