我已经在我的模板中使用设备检测(http://djangosnippets.org/snippets/2228/)并尝试使其在视图中工作,因此如果用户来自iPhone,我可以重定向到应用商店.
所以我已经:
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 }
然后在tools/middleware.py中创建了一个类:
from tools.context_processor import mobile
class detect_device(object):
def process_request(self, request):
device = mobile(request)
request.device = device
在settings.py中将以下内容添加到MIDDLEWARE_CLASSES:
'tools.middleware.detect_device'
在views.py中,我创建了:
def get_link(request):
if request.device.iphone:
app_store_link = settings.APP_STORE_LINK
return HttpResponseRedirect(app_store_link)
else:
return HttpResponseRedirect('/')
但是我收到了错误:
'dict'对象没有属性'iphone'
这是一本字典,而不是一堂课.
完整视图:
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('/')
