Question

I use the

Post.order(:created_at)

in the controller and the posts are ordered by create time, but it come out from the oldest to the newest post, that is what i don’t want, I want to change the order to display the recent posts first, how can I change the code?

Answer 1

Use Post.order("created_at desc")

Tip: Use a scope so this logic remains on your model, not on your controller.

class Post < ActiveRecord::Base 
  scope :recent_first, order("created_at desc")
end

Then, on your controller, you can just use Post.recent_first.
