高手接招! 在django的通用视图里面做判断

Question

我用django的通用视图代码是这样的: class IndexView(BaseView, ListView): ismobile = True if ismobile: template_name = "m/index.html" else: template_name = 'index.html' context_object_name = 'article_list' paginate_by = settings.PAGE_NUM # 分页--每页的数目 def get_queryset(self): article_list = Article.objects.filter(status=0) return article_list def get_context_data(self, **kwargs): # 轮播 kwargs['home']= True return super(IndexView, self).get_context_data(**kwargs) 大家可以帮我看下,我代码的第一句是ismobile = True意思就是判断是不是手机端方访问的.我的目的是想改成通过requests来判断,比如把代码改成这样 class IndexView(BaseView, ListView): #手机访问,用手机模板 if 'm.maidu.com' in self.request.get_host(): template_name = "m/index.html" 电脑访问用电脑模板 else: template_name = 'index.html' ....... 但是代码直接这样写会出错,会提示self不存在,我想下,如何优雅的解决这个问题?

Answer 1

试试这样的，不是用self，你类中应该写一个方法，这个方法其中有一个参数 是request

from django.utils.deprecation import MiddlewareMixin

class MultipleProxyMiddleware(MiddlewareMixin):

FORWARDED_FOR_FIELDS = [
    'HTTP_X_FORWARDED_FOR',
    'HTTP_X_FORWARDED_HOST',
    'HTTP_X_FORWARDED_SERVER',
]

def process_request(self, request):
    """
    Rewrites the proxy headers so that only the most
    recent proxy is used.
    """
    for field in self.FORWARDED_FOR_FIELDS:
        if field in request.META:
            if ',' in request.META[field]:
                parts = request.META[field].split(',')
                request.META[field] = parts[-1].strip()

Answer 2

继承View类
在class IndexView(BaseView, ListView):添加View，即：
class IndexView(BaseView, ListView，View):就可以调用self.request
