'NoneType'對象沒有屬性'META'

以下是我的Django 1.10 views.py代碼，它生成我的博客RSS提要。我現在試圖將我的使用情況統計跟蹤添加到此。'NoneType'對象沒有屬性'META'

我將我所有的統計代碼保存在我的項目的指定區域。我所需要的是rss views.py中的這3行代碼。這在我的其他views.py，只是不在我目前吸引的rss之一。

from statistics.service.add import ServiceAdd as ServiceStatisticsAdd 
rss_reference = {'utc': timezone.now()} 
ServiceStatisticsAdd(request).add('rss', rss_reference, kwargs)

我得到的錯誤是所有關於要求。本來數據庫def是def items（self）：。當我去添加追蹤我預計包括請求將已修復錯誤。

這是我views.py

from datetime import datetime 

from django.contrib.syndication.views import Feed 
from django.urls import reverse 
from django.utils import timezone 

from database.ron_home.models import BlogWebsite 
from statistics.service.add import ServiceAdd as ServiceStatisticsAdd 


class BlogRssFeed(Feed): 
    title = "Rons-Home.net Blog RSS Feed" 
    link = "/en/blog/" 
    description = "Ron Piggott shares updates from his health care and logistics of daily living with a physical disability." 

    def item_title(self, obj): 
     return obj.entry_title 

    def item_description(self, obj): 
     return obj.entry 

    def item_link(self, obj): 
     return reverse('blog:entry', args=[obj.reference]) 

    def items(self, request, **kwargs): 
     rss_reference = {'utc': timezone.now()} 
     ServiceStatisticsAdd(request).add('rss', rss_reference, kwargs) 
     return BlogWebsite.objects.filter(entry_date__lt=datetime.utcnow()).order_by('-entry_date')[:15]

這是完整的回溯

哪裏是你的'ServiceStatisticsAdd'功能？你是否正確傳遞了請求？ – Bobby

@Bobby我從其他views.py複製了這3行代碼。他們是正確的。實際的ServiceStatisticsAdd位於'統計'子模塊中。 –

我認爲這是一個有點棘手。這種方法添加到BlogRssFeed

def get_feed(self, obj, request): 
    self.custom_var = request 
    return super().get_feed(obj, request)

然後

ServiceStatisticsAdd(self.custom_var).add('rss', rss_reference, kwargs)
