This error appears in the last trunk, it not appears in 6473 version and I
don't get it in all pages.

Comment:

It seems the issue is not with http but with the cache_page decorator. The
decorator worked with the previos version and does not work with the trunk
versions.

This worke on version 6473
{{{
def ajax_zonas(request):
"""Get all ojects from table Provincia odrdereb by name"""
listado = Provincia.objects.all().order_by('name')
json = serialize('json', listado,ensure_ascii=True)
return HttpResponse(json, mimetype='text/javascript')
ajax_zonas = cache_page(ajax_zonas, 60)
}}}

No feedback since several months. Closing it, since some people said
'worksforme'.

Please reopen if problem still happens with current SVN trunk.

Comment:

This still doesn't seem to work in the svn trunk. I get the following
error:

Traceback (most recent call last):

File "G:\Python25\lib\site-packages\django\core\servers\basehttp.py",
line 277, in run
self.result = application(self.environ, self.start_response)

if response.status_code == 404:

AttributeError: 'function' object has no attribute 'status_code'

I use cache_page in urls.py. Using @cache_page in views seems to work
though (or at least no errors were generated).
I have the following middleware set:

MIDDLEWARE_CLASSES = (
'django.middleware.cache.CacheMiddleware',
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.middleware.doc.XViewMiddleware',
)

I couldn't determine if CacheMiddleware was needed for individual views or
not so I've tested with and without it, with the same result.

Comment:

@MihaiD: I have been able to reproduce the problem by using
{{{cache_page}}} in the URLconf as you describe but by using the string
syntax for the view being "decorated" instead of the callable syntax (see
http://www.djangoproject.com/documentation/release_notes_0.96/#urlconf-
improvements). This confuses
{{{django.utils.decorators.decorator_from_middleware()}}} than then ends
pushing a stub function as a decorator/middleware method parameter in a
place where a !HttpResponse is expected.

{{{
#!python

import views

urlpatterns = patterns('',
(r'^foo/$', cache_page('myproj.myapp.views.myview')), # This is WRONG
(r'^foo/$', cache_page(views.myview)), # This is OK
)
}}}

Can you confirm this is what you are doing in your setup?. If so, I will
then change Component field of this ticket to ''Documentation'' and will
submit a patch against the URL dispatcher docs to clarify this.
