高手接招! 在django的通用視圖里面做判斷

Python

慕田峪7331174 2019-02-20 21:17:08

我用django的通用視圖代碼是這樣的: 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 # 分頁--每頁的數(shù)目 def get_queryset(self): article_list = Article.objects.filter(status=0) return article_list def get_context_data(self, **kwargs): # 輪播 kwargs['home']= True return super(IndexView, self).get_context_data(**kwargs) 大家可以幫我看下,我代碼的第一句是ismobile = True意思就是判斷是不是手機端方訪問的.我的目的是想改成通過requests來判斷,比如把代碼改成這樣 class IndexView(BaseView, ListView): #手機訪問,用手機模板 if 'm.maidu.com' in self.request.get_host(): template_name = "m/index.html" 電腦訪問用電腦模板 else: template_name = 'index.html' ....... 但是代碼直接這樣寫會出錯,會提示self不存在,我想下,如何優(yōu)雅的解決這個問題?

試試這樣的，不是用self，你類中應(yīng)該寫一個方法，這個方法其中有一個參數(shù) 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()
