How do you reference only the persisted records in an active record association

Question

In the edit method of many controllers you initialize a new object and edit existing objects

class MagazinesController < ApplicationController
   def edit         


        

Answer 1

You could always reject pages that are new records...

%h4 Existing pages
- @magazine.pages.persisted.each do |page|
    %p= link_to page, page.title

where on Page you'd have something like:

def self.persisted
  reject {|page| page.new_record? }
end
