Use Redis to Make your Ruby objects Likeable!
You like this
Likeable is the easiest way to allow your models to be liked by users, just drop a few lines of code into your model and you're good to go.
class Comment
include Likeable
# ...
end
class User
include Likeable::UserMethods
# ...
end
Likeable.setup do |likeable|
likeable.redis = Redis.new
end
comment = Comment.find(15)
comment.like_count # => 0
current_user.like!(comment) # => #<Likeable::Like ... >
comment.like_count # => 1
comment.likes # => [#<Likeable::Like ... >]
comment.likes.last.user # => #<User ... >
comment.likes.last.created_at # => Wed Jul 27 19:34:32 -0500 2011
comment.liked_by?(current_user) # => true
current_user.all_liked(Comment) # => [#<Comment ...>, ...]
liked_comment = Likeable.find_by_resource_id("Comment", 15)
liked_comment == comment # => true
Setup
Gemfile:
gem 'likeable'
Next set up your Redis connection in initializers/likeable.rb:
Likeable.setup do |likeable|
likeable.redis = Redis.new
end
Then add the Likeable::UserMethods
module to models/user.rb:
class User
include Likeable::UserMethods
end
Finally add Likeable
module to any model you want to be liked:
class Comment
include Likeable
end
Thats about it.
