feedjira-redis

FeedjiraRedis uses Datamapper's dm-redis-adapter to provide a persistance layer for the feedjira RSS/Atom feed consumption library.

Example Usage

FeedjiraRedis can be used in much the same fashion as feedjira itself. One common use for FeedjiraRedis is to avoid updating the feed with every page hit, so you could update the feed from a Rakefile on a cron job instead.

Shared

DataMapper.setup(:default, { :adapter  => 'redis' })
FEED_URL = 'https://github.com/logankoester/feedjira-redis/commits/master.atom'

Rakefile

namespace :blog do
  desc 'Grab the latest blog posts'
  task :update do
    FeedjiraRedis::Feed.fetch_and_parse(FEED_URL)
  end
end

FeedjiraRedis::Feed is actually a Datamapper model that wraps the interface to Feedjira::Feed with some code to add persistence. Feeds are uniquely identified by their feed_url property, so when you call fetch_and_parse or update a second time the new entries are associated with the original feed.

Run rake blog:update to grab some entries.

Action

Now you just need to fetch the object your Rakefile created.

@feed = FeedjiraRedis::Feed.first(:feed_url => FEED_URL)

View

FeedjiraRedis::Entry is also a Datamapper model, but it shares the same properties as Feedjira::Entry.

%h1= @feed.title
  - @feed.entries.each do |e|
    %h2= e.title
    %p= e.content

See the Feedjira documentation or read the code (it's short!) for further details.

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
Fork the project

Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
