EXTRA! EXTRA! READ ALL ABOUT IT!
Need to add a news feed to your application? EXTRA! EXTRA! is just the Gem for you! This is a common need for many social applications. EXTRA! EXTRA! uses MongoDB to give you super fast, super convenient feeds.
Not all of this works yet. This is just a prerelease. README driven development FTW!
EXTRA! EXTRA! will be distributed via Rubygems, so just
$ gem install extraextra
and you'll be reading the news in no time!
The source of EXTRA! EXTRA! is on GitHub, and can be found here:
It can be cloned via
$ git clone git://github.com/steveklabnik/extraextra.git
**Ruby 1.9** Sorry for you 1.8 people, 1.9 is the current version of Ruby.
*mongo* If you're going to use MongoDB…
The first thing you'll need to do is configure EXTRA! EXTRA! to use your MongoDB installation.
Extra::Extra.source :host => "localhost", :port => "1337"
To record something newsworthy, just do this:
$ Extra::Extra::! :breaking, user, "has just done something awesome!"
To find out what interesting things a particular user has done:
$ Extra::Extra.read_all_about_it user
$ Extra::Extra.the_scoop user
This returns an array of Extra objects. To find out more about a particular
Extra: $ extra = Extra::Extra::! :sports, user, "hit a home run!" $ extra.who => #<User:0x0000010089ea80> $ extra.what => "hit a home run" $ extra.where => nil # currently undecided $ extra.when => 1283311813 $ extra.how => nil # currently undecided $ extra.to_s => "Steve hit a home run"
The name in to_s comes from user#username. If you use something else… I'll provide a way to override this eventually.
To only see breaking news:
This will filter out only the news in the 'breaking' category.
To find out what interesting things a users's friends have done:
To define what who you're friends with, make a method on your user model named my_peeps. For a (hypothetical) example:
class User def my_peeps User.friends.collect(&:id) end end
The my_peeps method should return an Array of ids. This method will be called during scope_the_scene to determine what results get returned.
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
