Question

I have an array of posts called @posts. Post model has_many :feelings :through => :feelingships.

How do I take the array of posts and narrow them it down to only the posts with a specific feeling?

I tried the code below but it doesn’t work 🙁

@specific_feeling_posts = @posts.feeling.where(:feeling => "happy") 

Models

class Post < ActiveRecord::Base
  has_many :feelingships
  has_many :feelings, :through => :feelingships
  belongs_to :user
end

class Feeling < ActiveRecord::Base
  has_many :feelingships
  has_many :posts, :through => :feelingships
end

class Feelingship < ActiveRecord::Base
  belongs_to :post
  belongs_to :feeling
end

Answer 1

@happy_posts = Post.joins(:feelings).where("feelings.title = ?", "happy")

That should work.
