I'm building an app where users can decide when their posts will be deleted, but I don't know how to do it in Rails 3.

When to delete posts? Do you mean deleting records based on schedule (as in Deadtime field)? – edthix Apr 16 '11 at 11:03

Sometimes you can inactivate a post rather than executing the database command "delete". If you inactivate, then you'll keep statistics and comments.
class Post
attr_protected :published_on, :deleted_on
belongs_to :user
scope :published, lambda{ where("published_on >= ?", Time.now).where("deleted_on IS NULL or deleted_at < ?", Time.now)}
end
in your controller later:
@posts = @user.posts.published.paginate(params[:page])

I assume you want the posts to be automatically deleted on a certain date(time) and your users are able to set that date(time). To achieve that you must use cron jobs. Here you can find more about it.
Another (real dirty) solution is to execute a method each time your app is accessed and look for the posts that needed to be deleted.
