Rails ActiveRecord How to get array of associated models

I am using Ruby on Rails 4.0.1 and I would like to get the array of associated models. That is, I have the following models and associations:

class Post < ActiveRecord::Base
  has_many :comments, dependent: :destroy
  has_many :likes, dependent: :destroy
end

class Comment < ActiveRecord::Base
  belongs_to :post
end

class Like < ActiveRecord::Base
  belongs_to :post
end

And I would like to get the array of associated models likes following.

Post.has_many_associated
=> [:comments, :likes]

Any Idea?

Thank you for your advice.

Tae-ho.

Yes, you can do this with reflect_on_all_associations:

Post.reflect_on_all_associations(:has_many).map(&:name)
