Acts as Recommended
A simple rails 3 engine to add recommendation functionallity to your application
Add to your Gemfile
And just run
First thing we need is the recommendation model himself and we have a generator that creates the model's tables
rails g acts_as_recommended:tables
After that we can add the required fields for our models with another generator
rails g acts_as_recommended:recommendations_for Post
This will add a migration adding the required fields to add recommendations to a certain model.
Then all we simply add this line to our desired model
Now, we can run the migrations and we can already recommend whatever we want!
post = Post.first bob = User.first joe = User.last mary = User.find(100) post.recommend!( true, bob ) post.recommend!( 0, joe ) post.recommend!( true, mary ) # good minus bad recommendations post.recommendations # 1 post.recommendations_count # 3 post.good_recommendations # 2 post.bad_recommendations # 1 post.good_recommendations_percent # 66.67 # pass a format optionally post.bad_recommendations_percent( '%.1f' ) # 33.3 # check if user recommended post.recommended_by?( bob ) # true post.recommended_by?( joe ) # true # get user's recommendation post.get_recommendation_of( bob ) # true post.get_recommendation_of( joe ) # false
Note: users can only recommend once, a second recommendation will replace the latter
By default the recommendation must be done by a User model you can customize that with a simple initializer like config/initializers/recommendations.rb
