Edit Question
Title
Body
I was following the screencast on rubyonrails.org (creating the blog). I have following models: comment.rb class Comment < ActiveRecord::Base belongs_to :post validates_presence_of :body # I added this end post.rb class Post < ActiveRecord::Base validates_presence_of :body, :title has_many :comments end Relations between models work fine, except for one thing - when I delete a post record, I'd expect RoR to delete all related comment records. I understand that ActiveRecords is database independent, so there's no built-in way to create foreign key, relations, ON DELETE, ON UPDATE statements. So, is there any way to accomplish this (maybe RoR itself could take care of deleting related comments? )?
