A Django app using 'feedparser' to fetch and parse a feed to render it from a template
Project description
A Django app using feedparser to fetch and parse a feed to render it from a template.
It is not a Feed agregator since it manage feeds one by one.
requests is used to fetch feeds;
feedparser is used to parse feeds;
Django cache is used to avoid fetching again the feed each time;
Basic feed renderers just parse the feed without modifying anything but you can extend it to implement your post-process formatting;
Once the feed has been fetched, it can be displayed through a template. Default template is really basic and you should eventually override it or create another one to fit to your feed structure/format;
A DjangoCMS plugin is available on cmsplugin_feedparser;

Requires
six;
Django >= 1.4;
requests >= 2.7.0’,
feedparser >= 5.1.3’,
Install
First install the package:
pip install django-feedparser
Add it to your installed Django apps in settings:
INSTALLED_APPS = (
...
'django_feedparser',
...
)
Then import its settings:
from django_feedparser.settings import *
And finally see about Available settings you can override.
Usage
Renderers
There is actually two basic renderer available:
- basic-xml
Just the basic renderer, parsing an XML feed and return result given by feedparser.
Don’t do any special formatting.
- basic-json
Like basic-xml but for a JSON feed, obviously don’t use feedparser but the json builtin from Python and return the loaded object.
Finally, remember than your renderer have to be compatible with the used template and vice-versa.
Views
There is a mixin django_feedparser.views.FeedFetchMixin you can inherit from your views to exploit a feed.
And there is a basic view django_feedparser.views.FeedView that inherits from mixin FeedFetchMixin to demonstrate its usage. However the basic view is usable as it if it meets your needing, if so you just have to use it directly in your urls like django.views.generic.base.TemplateView:
from django.conf.urls import *
from .views import FeedView
urlpatterns = patterns('',
...
url(r'^myfeed/$', FeedView.as_view(feed_url="http://localhost/myfeed.xml"), name="myfeed"),
...
)
