RSS Feed

Synopsis

Fetch RSS feeds, collect entries using Feedzirra gem and feed your database.

Installation

gem install rss-feed

Or put in your Gemfile:

gem "rss-feed"

Then (obviously) type bundle in your favorite command line interface.

You may encounter some issue when installing (I did). Some dependencies must be satisfied. On Ubuntu, the dependencies can be satisfied by installing the following packages:

sudo apt-get install libcurl3 libcurl3-gnutls libcurl4-openssl-dev

Usage

In your model:

class Article
  include Mongoid::Document
  include Rss::Feed

  # Add this line to set which RSS feed this model must subscribe to
  subscribes_to "https://news.google.fr/news/feeds?output=rss"
end

Your model get thus some methods:

# Get subscribed feed url
Article.feed_url # => "https://news.google.fr/news/feeds?output=rss"

# Get already loaded feed entries
Article.feed_entries # => [] # because the feed has not been loaded

# Load feed from feed_url
Article.get_feed
Article.feed_entries # => the collection of the feed entries

# (Re)load and store the feed entries as model documents
Article.update_from_feed

Rake task

A Rake task has been implemented to enable you automatically get new feed entries for every models that have subscribed to an RSS feed (i.e. Model.subscribes_to is present in your involved models). Simply do:

rake rss:feed:update
