How to add an image to the body of an RSS-article?

Answer 1

A -- maybe not technically best -- approach that works so far for me is to define my own template. Even it's not encapslled in CDATA or using the enclosure-tag of RSS it appers to be rendered correctly in most of the RSS reader I'Ve tried -- so a clear "works for me".

     description_template = "feeds/latest.html"

The template is a normal Jinja-template, which is not uspporting full set of HTML. However, for my little project a template like

<h1>{{ obj.description_short}}</h1>
<img src="{{request.scheme}}://{{request.META.HTTP_HOST}}{{obj.image.medium.url}}" />

(Not happy with the build of URL, but this should be solveable with e.g. the idea of another answer

    def item_extra_kwargs(self, item):
       …

So my complete view looks something like this:

class LatestFeed(Feed):
    title = "Latest Items"
    description = "Latest Items"
    link = "/"
    description_template = "feeds/latest.html"

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

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

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

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

Try this:

...

class LatestItems(Feed):
    ...

    def item_image(self, item):
        domain = 'https://example.com'
        return domain + item.image.url

...

Create a custom feed_type and set in the Feed view,

from django.contrib.syndication.views import Feed
from django.utils.feedgenerator import Rss201rev2Feed
from django.conf import settings


class CustomFeed(Rss201rev2Feed):
    def add_item_elements(self, handler, item):
        super().add_item_elements(handler, item)
        handler.addQuickElement("image", item["image"])


class LatestItems(Feed):
    feed_type = CustomFeed
    title = "LatestItems"
    description = "Latest Items"
    link = "/sitenews/"

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

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

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

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

    def get_context_data(self, **kwargs):
        setattr(self, 'request', kwargs['request']) # to access the request object later
        return super().get_context_data(**kwargs)

    def item_extra_kwargs(self, item):
        img_url = item.image.url
        request_url = self.request.build_absolute_uri('/')[:-1]
        image_url_abs = f"{request_url}{settings.STATIC_URL}{img_url}"
        return {
            'image': image_url_abs
        }

Result
