'NoneType' 对象没有属性 'META'
'NoneType' object has no attribute 'META'
以下是我的 Django 1.10 views.py 代码，它生成我的博客 RSS 提要。我现在正在尝试将我的使用情况统计跟踪添加到此。
我将所有统计代码保存在项目的指定区域中。我只需要 rss views.py 中的这 3 行代码。这在我的另一个 views.py 中有效，只是在我目前很烂的 rss 中无效。
from statistics.service.add import ServiceAdd as ServiceStatisticsAdd
rss_reference = {'utc': timezone.now()}
ServiceStatisticsAdd(request).add('rss', rss_reference, kwargs)
我收到的错误都是关于 request。最初数据库 def 是 def items(self):。当我去添加跟踪时，我预计包括 request 会修复错误。
这是我的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]
这是完整的回溯
