django-rss2rest

rss2rest

• Configure your feeds in the settings file
• Turns RSS feeds into a RESTful API with the use of TastyPie and Feedparser (perfect for use with backbone.js)
• Map feeds to Django models, few convenienve models are provided (see below)
• Write your own mdels representing a feed item, you just need to provide a mapping from feed nodes to model fields
• Harvest feeds using ./manage.py syncdb command
• Access your feeds direct via tastypie API resource

Installation

Install via PIP:

$ pip install django-rss2rest

Add to your INSTALLED_APPS the following:

INSTALLED_APPS = [
    ...,
    'tastypie',
    'rss2rest',
]

Define your feeds:

RSS2REST_FEEDS = [
    {'feed': 'http://feedurl/',
     'model': 'rss2rest.FeedItem'},
]

Add RESTful routing to your urls.py:

from rss2rest.api import FeedItemResource
feed_item_resource = FeedItemResource()
urlpatterns += patterns('rss2rest',
    (r'^api/', include(feed_item_resource.urls)),
)

Usage

Synchronise Feeds:

./manage.py syncrss2rest

Consume feeds go to:

http://127.0.0.1/rss2rest/api/<resource_name>

Models for your feeds

In order for the feed to be exposed as a RESTful resource the feed must be mapped to a django model. rss2rest provides a few pre-defined models that fit some typical scenarios.

Generic feed item models:

• FeedItem - generic feed item
• VimeoFeedItem - maps well to Vimeo Likes RSS feed
• FlickrFeedItem - maps well to Flickr Likes RSS feed

Writing your own feed item model:

• Create your own model for the feed to provide custom mapping, etc
• Simply extend the abstract AbstractFeedItem class present in the rss2rest.models file.
• Put MAPPING dictionary as a class property and you're ready to go
• Make sure you put your new model class name (as string in the format of app.ModelName) into the RSS2REST_FEEDS setting
• If your model is pretty generic and maps to a public feed - make sure you submit it as a pull request with accompanying tests to be included in the rss2rest

Generic tasty pie resources

• FeedItemResource - resource name: feed_item
• FlickrItemResource - resource name: flickr
• VimeoItemResource - resource name: vimeo

Custom resources

• You can build your custom resource as per Tastypie's documentation

Contribute

Set up in development mode:

$ git clone git://github.com/gump/rss2rest.git
$ cd rss2rest
$ mkvirtualenv rss2rest
$ python setup.py develop
$ cd sandbox/
$ cp local_settings_sample.py local_settings.py
$ ./manage.py syncdb
$ ./manage.py test rss2rest

Planned development

• More tests for all types of feeds
• More generic feed item models to cater for other common use cases
• published flag on abstract model to drive presence in the RESTful API (configurable with publish/unpublish flag using django admin panel); way to define default behaviour using a setting
• Defining your feeds in the database
