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.
Contributing to feedjira-redis
- 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
- Start a feature/bugfix branch
- 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.
