Issues with a trigger module ("beep"). Module is not updating or changing labels in the hook_action_Info() hook

Question

i'm learning Drupal and was going through this text book to do so: "Pro Drupal 7 Development by Todd Tomlinson".

Chapter 3 of the book teaches readers about hooks actions and triggers. It does this by taking you through the steps of creating a module called beep that involves making a function that implements hook_action_info() to write the word Beep! to log when an event takes place.

The issue I am having is that I can enable the module in the module page and once I do it works and i see the label 'Beep annoyingly' as a selectable option but when I change the label to something else like 'Beep elegantly' it doesn't change. Nothing is updating and it just stays as Beep annoyingly every time. Am I missing something? I've cleared the caches and everything too. I was thinking it might be a simple PHP syntax error but i cannot find it and have been struggling over this for some time now.

I've provided the code below. You should be able to make a module yourself with this. I'd provide the files themselves but I don't see a way to do that in this forum. Can anyone else get the labels to change? If your awesome enough to try this. make sure you have the triggers module enabled first. Thanks!

For the beep.module file:

<?php 
/**
 * @file
 * Provide a simulated beep.
 */
function beep_beep() {
  watchdog('beep','Beep!');
 }
/**
 *Implementation of hook_action_info().
 */
function beep_action_info() {
  return array(
    'beep_beep_action' => array(
      'type' => 'system',
      'label' => t('Beep annoyingly'),
      'configurable' => FALSE,
      'triggers' => array('node_view', 'node_insert', 'node_update', 'node_delete'),
    ),
  );
}
/**
 * Simulate a beep. A Drupal action.
 */
function beep_beep_action() {
  beep_beep();
}

HERE IS THE CODE FOR THE beep.info FILE.

name = Beep
description = "Simulates a system beep."
package = Pro Drupal Development
core = 7.x
files[] = beep.module

Answer 1

The thing is that the system registers an action with the system name beep_beep_action and probably stores that in a cache. That way it's easier and faster to access the right function in your files. I've however not found that cache, nor a way to clear it.

There are three things you can do:

• Accept that all others who install your module will see it right.
• Rename beep_beep_action and beep_beep_action() to something else and you will register a fresh action.
• Open the database and find and remove the stored action. (But only if you know what you are doing.)

I'd go for the second approach.
