It sounds like you want to automagically do something like:
if request.is_mobile:
return render_to_response('test_mobile.html',{})
return render_to_response('test.html',{})
I'm not sure that will be possible without modifying your views. I did
something similar by determining which base template all my templates
should extend. Here's what I did:
-Set request.is_mobile if the user is using a mobile browser. I happened
to use the same middleware you posted but tweaked it to allow viewing the
desktop version of a page on a mobile device by setting the cookie
'force_device' - http://pastie.org/4445761
-Add a context processor that defines which base template to use based on
request.is_mobile - http://pastie.org/4445772
-Chances are your templates currently extend base.html or something.
Change all those to {% extends BASE_TEMPLATE %}
Now all your templates will extend either base.html or base_mobile.html
based on the user agent. You can tweak the layout for the mobile site by
doing {% if request.is_mobile %}...{% else %}...{% endif %}, or if you are
going to have drastically different content if the user is on mobile, you
can define two content blocks in your test.html template, "content" and
"content-mobile", and then have base.html and base_mobile.html render each
of those blocks.
