How to access data in get_context_data RSS Feed django 2.2


I'm trying to access the context dictionary that is returned by a modified 'get_context_data' function in the LatestVideosFeed so I can use it in a 'news feed' I'm trying to make because the context that is returned contains the author of the video. I've been following these docs https://docs.djangoproject.com/en/2.2/ref/contrib/syndication/ and I can't figure out how to access the context dictionary that returns from the get_context_data(self, item, **kwargs): It works and when I do a debug print just before the return it returns a dictionary with the last entry as the user that uploaded the video. the debug print is print(context['author']) which returns as expected everytime the feed is interacted with.

feeds.py

class LatestVideosFeed(Feed):
    link = '/video-feeds/'
    description = 'New Video Posts'

    def items(self):
        return VideoPost.objects.all()

    def get_context_data(self, item, **kwargs):
        context = super().get_context_data(**kwargs)
        context['author'] = item.author
        print(context['author'])
        return context

    def item_title(self, item):
        return item.title

    def item_description(self, item):
        return item.description

    def item_link(self, item):
        return reverse('video_post', args=[item.pk])

views.py

def video_list(request):
    feeds = feedparser.parse('http://localhost:8000/profs/video-feeds')
    return render(request, 'vids/video_list.html', {'feeds': feeds})

template

{% for thing in feeds.entries %}
        <h1>Author</h1><br>
        {{thing.author}} <-- Nothing is printed here
        <h1>Title</h1>
        {{thing.title}}<br>
        <h1>Description</h1>
        {{thing.summary}}<br>
        <h1>Video Link</h1>
        <a href="{{thing.link}}">{{thing.title}}</a><br>
{% endfor %}



Solution

  • I read a little bit more into the docs I provided and noticed that the SyndicationFeed allows you to add items, one of the parameters was author_name, so I replaced get_context_data function with an item_author_name function that returned item.author and Boom! I accessed it through the feeds.entries loop in the template (old and new code below for better context)

    # Old Code
    def get_context_data(self, item, **kwargs):
            context = super().get_context_data(**kwargs)
            context['author'] = item.author
            print(context['author'])
            return context 
    
    # New Code
    def item_author_name(self, item):
            print('Being Called')
            return item.author
