CakePHP counterCache

I'm using counterCache to track the number of chapters that have been posted to their related stories.

This all works fine, apart from the fact that when the chapter_count field in the database gets updated, the modified field开发者_如何学编程 for that record does not.

Is there any way that I can set Cake to automatically update the modified field when the counterCache functionality runs?

Thank you.

I assume you have a modified field in the chapters table? Cakes default behaviour is to update it for that specific record.

You could add a count_modified column to the table, and then in your models beforeSave() you could assign the current timestamp to that and then save it.

Something like perhaps,

function beforeSave(){
  $this->data['Chapter']['count_modified'] = date();
}

Which should then save that column every time the model performs a save action. Here's the method, http://api.cakephp.org/class/model#method-ModelbeforeSave and a book link, http://book.cakephp.org/view/683/beforeSave
