以下是我的Django 1.10 views.py代码,它生成我的博客RSS提要。我现在正在尝试将此使用情况统计信息跟踪添加到此。

我将所有统计代码保存在项目的指定区域。我需要的只是rss views.py 中的这三行代码。这适用于我的其他views.py,而不是我目前正在使用的rss。

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

我得到的错误完全与请求有关。最初数据库def是 def items(self):。当我去添加跟踪时,我预计包括请求会修复错误。

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]

这是完整的追溯

我认为这有点棘手。将此方法添加到BlogRssFeed

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

然后

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