copied!<p>Regarding this article: <a href="http://archives.ryandaigle.com/articles/2008/3/31/what-s-new-in-edge-rails-dirty-objects" rel="nofollow">tracking activerecord objects</a></p> <p>I need to know what fields are changed in a big form using accepts_nested_attributes_for.</p> <p>Currently the form works well as expected. But in addition I'm doing a "log history" about user's changes.</p> <p>I have tried the hash mapping, but is really complicated to me since the models aren't small, and talking about the above article maybe exists a better way to track changes.</p> <p>My models are (in case is necessary):</p> <pre><code>class Customer < ActiveRecord::Base has_many :addresses attr_accessible :nom, :prenom, :langue, :nationalite, :codeFiscal, :hidden_status, :subscribed attr_accessible :addresses_attributes, allow_destroy: true accepts_nested_attributes_for :addresses end class Address < ActiveRecord::Base belongs_to :customer has_many :telephones attr_accessible :flag, :societe, :titre, :persContact, :rue, :rue1, :nopostal, :lieu, :pays attr_accessible :hidden_status attr_accessible :telephones_attributes accepts_nested_attributes_for :telephones, :reject_if => :all_blank, :allow_destroy => true end class Telephone < ActiveRecord::Base belongs_to :address attr_accessible :typeNumero, :numeroTel end </code></pre> <p>(models are very normal).</p> <p>Any ideas?, and if I'm forced to map the hash, have you a little sample about how to ?</p> <p>Thanks in advance</p>
