'NoneType' object has no attribute 'META'

Question

The following is my Django 1.10 views.py code which produces my blog RSS feed. I am now trying to add my usage statistics tracking to this.

I am keeping all my statistics code in a designated area of my project. All I need are these 3 lines of code within the rss views.py. This works in my other views.py, just not in the rss one I am presently suck on.

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

The error I am getting is all about request. Originally the database def was def items(self):. When I went to add tracking I expected including request would have fixed the error.

This is my 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]

This is the complete traceback

Answer 1

I think it is a bit tricky. Add this method to BlogRssFeed

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

Then

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