How to properly create a associated record just after the associator record creation?

Question

I am using Ruby on Rails 4.1 and I would like to know if it is good and what are the drawbacks of creating a associated record just after the associator record creation. That is, for example, I have the Article class and the Comment class that belongs_to Article and I would like to create a "default" comment just after an article is created.

Probably I can use a callback method to accomplish that, but are there other approaches to accomplish what I looking for? What should I look at to be "balanced" (eg: class/module dependencies)?

Answer 1

You are looking for something along the lines of...

Class Article

  has_many :comments

  after_create :create_first_comment!

  def create_first_comment!
    comments.create
  end

end
