How to convert an ActiveRecord_AssociationRelation into an array in ActiveRecord?

How can I convert an ActiveRecord_AssociationRelation into an array of Rails model instances?

I have code that is in an after_save hook like this:

class Like < ApplicationRecord
  belongs_to :likee, class_name: 'User', foreign_key: 'likee_id'
  belongs_to :liker, class_name: 'User', foreign_key: 'liker_id'

  after_save :mutual_like?

  private

  def mutual_like?
    if liker.likes.where(likee: liker) // returns collection proxy but I want to return an array of model instances so that I can create another model

    end
  end
end

Is there a way to return an array of instances instead?

Table for reference:

  create_table "likes", force: :cascade do |t|
    t.integer  "liker_id",      null: false
    t.integer  "likee_id",      null: false
    ...
  end

I believe the problem is that Rails is not associating the models based on the foreign key of likee_id / liker_id.

Try ActiveRecord#to_a.

liker.likes.where(likee: liker).to_a

to_a() public

Converts relation objects to Array.
