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()

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
