Hello.

Okay i have two models: posts and comments. as you can think comments has column :post_id.

My models

Comments

• belongs_to :post

Post

• has_many :comments

So, this is pretty simple association but i have some problems with ordering comments. at first time, when i create my comments migration file i just add column :position. This column indicate comment position in the post.

But now i think what where is more good way to do this.

so i can't make my choise:

1) uses t.column :datatime :created_at, :default => Time.now()

2) or use timestamps? this is undiscovered for me, please tell me about your exp.
