= dependent => :protect option Adds a new option :protect for the parameter <tt>:depends</tt> from +has_many+, +has_one+ and +belongs_to+ methods. This option forbids destroying records with associated records in an association created with <tt>:dependent => :protect</tt> option, more or less like <tt>ON DELETE RESTRICT</tt> SQL statement. If you try to destroy a record with associated records it will raise an ActiveRecord::ReferentialIntegrityProtectionError (defined also in this plugin). Based on the idea and the code from [email protected] in Ruby on Rails ticket #3837 (https://dev.rubyonrails.org/ticket/3837) and plugin from Daniel Rodríguez Troitiño <[email protected]> in https://svn.ruido-blanco.net/dependent_protect/ == Author Sergio Cambra, based in a plugin from Daniel Rodríguez Troitiño <[email protected]>, and the ideas and the code from <[email protected]>.
