Friendis

TODO: Write a gem description

Add this line to your application's Gemfile:

gem 'friendis'

And then execute:

$ bundle

Or install it yourself as:

$ gem install friendis

create an initializer in config/initializers/friendis.rb:

Friendis.configure do |c|
  #...
end

The following options exist:

• redis_connection: an existing Redis connection, defaults to a Redis.new instance.

All you need to do is to include the Friendable module:

include Friendis::Friendable

and to choose which attributes or methods will be cached in Redis for that user:

friend_this track: [:name, :picture]

Those fields will be changed in Redis after everytime you save the instance, note that your ORM needs to implement after_save and after_destroy since Friendis utilizes those callbacks to update and remove the cached data from Redis.

The id attribute will automatically be cached.

class User < ActiveRecord::Base
  include Friendis::Friendable

  friend_this track: [:name, :picture]
end 

@user1 = User.create(name: "Elad Meidar", picture: "http://picturez.com/elad.jpg")
@user2 = User.create(name: "Miki Bergin", picture: "http://picturez.com/miki.jpg")

@user1.send_friend_request(@user2)

@user2.pending_friend_requests

pending_friend_requests will return the cached attributes for the pending friend requests, in this case

[{"name" => "Elad Meidar", "picture" => "http://picturez.com/elad.jpg", "id" => 1}]

@user2.sent_friend_requests

sent_friend_requests will return the cached attributes for the sent friend requests, in this case

[{"name" => "Miki Bergin", "picture" => "http://picturez.com/miki.jpg", "id" => 2}]

@user2.approve_friend_request(@user1)

@user2.ignore_friend_request(@user!) #=> @user1 will still see the sent friend request.

@user1.friends

friends will return the cached attributes of the currently approved friends, in this case

[{"name" => "Miki Bergin", "picture" => "http://picturez.com/miki.jpg", "id" => 2}] 

@user1.is_friends_with?(@user2) #= true
@user1.is_friends_with?(@user3) #= false

@user1.unfriend(@user2)
