My cached page from 3.1 crashes because I have a middleware setting a
header.
Because cache_page do a pickle caching, we have a 3.1 JsonResponse running
on 3.2, without the new headers feature.
{{{
AttributeError: 'JsonResponse' object has no attribute 'headers'
File "django/core/handlers/exception.py", line 47, in inner
response = get_response(request)
File "commons/middleware.py", line 44, in __call__
response['X-Current-Version'] = VERSION
File "django/http/response.py", line 172, in __setitem__
self.headers[header] = value
}}}
Docs could provide some help about this, the fix should be easy cleaning
specific cache or using `CACHE_MIDDLEWARE_KEY_PREFIX`. that is
unfortunately broken.
