I need to change what template to use in a response based on type of user-agent in request. The middleware below works ok to detect mobile client, but I cannot get the template manipulation in the process_view method to work.
The middleware: # Credits: http://djangosnippets.org/snippets/2001/ import re class MobileDetectionMiddleware(object): """ Useful middleware to detect if the user is on a mobile device. """ def process_view(self, request, view_func, view_args, view_kwargs): if not request.is_mobile: return print vars(view_func), view_args,view_kwargs # these are allways blank/empty template = view_kwargs.get("template") if template is None and view_func.func_defaults: for default in view_func.func_defaults: if str(default).endswith(".html"): template = default break if template is not None: template = template.rsplit(".html", 1)[0] + ".mobile.html" try: get_template(template) except TemplateDoesNotExist: return else: view_kwargs["template"] = template return view_func(request, *view_args, **view_kwargs) def process_request(self, request): is_mobile = False if request.META.has_key('HTTP_USER_AGENT'): user_agent = request.META['HTTP_USER_AGENT'] # Test common mobile values. pattern = "(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|windows ce|pda|mobile|mini|palm|netfront)" prog = re.compile(pattern, re.IGNORECASE) match = prog.search(user_agent) if match: is_mobile = True else: # Nokia like test for WAP browsers. # http://www.developershome.com/wap/xhtmlmp/xhtml_mp_tutorial.asp?page=mimeTypesFileExtension if request.META.has_key('HTTP_ACCEPT'): http_accept = request.META['HTTP_ACCEPT'] pattern = "application/vnd\.wap\.xhtml\+xml" prog = re.compile(pattern, re.IGNORECASE) match = prog.search(http_accept) if match: is_mobile = True if not is_mobile: # Now we test the user_agent from a big list. user_agents_test = ("w3c ", "acs-", "alav", "alca", "amoi", "audi", "avan", "benq", "bird", "blac", "blaz", "brew", "cell", "cldc", "cmd-", "dang", "doco", "eric", "hipt", "inno", "ipaq", "java", "jigs", "kddi", "keji", "leno", "lg-c", "lg-d", "lg-g", "lge-", "maui", "maxo", "midp", "mits", "mmef", "mobi", "mot-", "moto", "mwbp", "nec-", "newt", "noki", "xda", "palm", "pana", "pant", "phil", "play", "port", "prox", "qwap", "sage", "sams", "sany", "sch-", "sec-", "send", "seri", "sgh-", "shar", "sie-", "siem", "smal", "smar", "sony", "sph-", "symb", "t-mo", "teli", "tim-", "tosh", "tsm-", "upg1", "upsi", "vk-v", "voda", "wap-", "wapa", "wapi", "wapp", "wapr", "webc", "winw", "winw", "xda-",) test = user_agent[0:4].lower() if test in user_agents_test: is_mobile = True request.is_mobile = is_mobile The view: from django.shortcuts import * def index(request): return render_to_response('testapp/test.html', {'user':request.user}) Any clues? -- Mvh/Best regards, Thomas Weholt http://www.weholt.org -- You received this message because you are subscribed to the Google Groups "Django users" group.
