Adding callbacks for Propel models in symfony project

September 11th, 2007
This is a simple how-to that describes adding callbacks for Propel models in symfony project (like those usefull methods in ActiveRecord::Callbacks module).

Step 1 : Enable Propel behaviors in config/propel.ini 



propel.builder.AddBehaviors = true     // Default value is false
Step 2 : Register the callback method and define it in model class - for example lib/model/Page.php

class PageTab extends BasePageTab
{
  function preSave(BaseObject $object, $con)
  {
    
  }
}

sfMixer::register('BasePageTab:save:pre', array('PageTab', 'preSave'));
Step 3 : Rebuild the model 


$ symfony propel-build-model
