Django - mobile device discovery in the looks

I already use device discovery ( http://djangosnippets.org/snippets/2228/ ) in my templates and try to get it to work in the views too, so I can redirect to the app store if the user comes from iPhone.

So, I already had:

import re def mobile(request): device = {} ua = request.META.get('HTTP_USER_AGENT', '').lower() if ua.find("iphone") > 0: device['iphone'] = "iphone" + re.search("iphone os (\d)", ua).groups(0)[0] if ua.find("ipad") > 0: device['ipad'] = "ipad" if ua.find("android") > 0: device['android'] = "android" + re.search("android (\d\.\d)", ua).groups(0)[0].translate(None, '.') # spits out device names for CSS targeting, to be applied to <html> or <body>. device['classes'] = " ".join(v for (k,v) in device.items()) return {'device': device }

And then create a class in tools / middleware.py:

 from tools.context_processor import mobile class detect_device(object): def process_request(self, request): device = mobile(request) request.device = device

The following MIDDLEWARE_CLASSES value has been added in settings.py settings:

 'tools.middleware.detect_device'

And in views.py I created:

 def get_link(request): if request.device.iphone: app_store_link = settings.APP_STORE_LINK return HttpResponseRedirect(app_store_link) else: return HttpResponseRedirect('/')

But I get an error message:

'dict' object has no attribute 'iphone'

IT vocabulary, not a class.

Full view:

 def get_link(request): if 'iphone' in request.device['device']: app_store_link = settings.APP_STORE_LINK return HttpResponseRedirect(app_store_link) else: return HttpResponseRedirect('/')
