You will probably need an another model - Like. 

class Comment < ActiveRecord::Base
  belongs_to :user
  has_many :likes
end
class Like < ActiveRecord::Base
  belongs_to :user
  belongs_to :commend
end

Controller:

def like
  Like. find_or_create_by_user_id_and_comment_id(current_user.id, params[:commend_id])
end

Something like this. You'll also have to take care of validation and so on.
