I am positive the problem is with your URL patterns:

Trying to access 'cn/bedroom' _should_ redirect to view Detail, I guess.
But what happens is that 'cn/' gets stripped via the main level pattern,
including 'final.photo.urls'. There no match is found due to the leading
'/' in the second pattern: r'^/bedroom/'. Thus the search continues with
'cn/(?P<path>.*)$' in the top-level URL patterns which tries to access a
non-existing media file in settings.MEDIA_ROOT.
Therefore, to fix the issue, you should remove the leading forward slash
'/' in the second pattern in your photo/urls.py.
For reference, see the notes section in
https://docs.djangoproject.com/en/1.4/topics/http/urls/#example
– "There's no need to add a leading slash, because every URL has that.
For example, it's ^articles, not ^/articles."
Best wishes,
Sebastian.
