How to get sfFormExtraPlugin working in Symfony 1.4 using Doctrine

I’m talking about this plugin: http://www.symfony-project.org/plugins/sfFormExtraPlugin

For some reason, getting the plugin to work took a lot of Googling and some trial and error.
So here is how I got it working. Hopefully I did this in the ‘correct’ way…

cd plugins
wget "http://plugins.symfony-project.org/get/sfFormExtraPlugin/sfFormExtraPlugin-1.1.3.tgz"
tar zxvf sfFormExtraPlugin-1.1.3.tgz
mv sfFormExtraPlugin-1.1.3 sfFormExtraPlugin
cd ..
./symfony plugin:publish-assets
cd web/js
wget "http://code.jquery.com/jquery-1.4.3.min.js"
wget "http://jqueryui.com/download/jquery-ui-1.8.5.custom.zip"
mkdir jquery-ui
cd jquery-ui
unzip ../jquery-ui-1.8.5.custom.zip
mv jquery-ui/css/smoothness ../css

Edit config/ProjectConfiguration.class.php to add sfFormExtraPlugin as an enabled plugin:

class ProjectConfiguration extends sfProjectConfiguration
{
  public function setup()
  {
    $this->enablePlugins(array('sfDoctrinePlugin', 'sfFormExtraPlugin'));
  }
}

Edit apps/<app_name>/config/view.yml to include the JS and CSS:

  stylesheets:    [main.css, smoothness/jquery-ui-1.8.5.custom.css]

  javascripts:    [jquery-1.4.3.min.js, jquery-ui/js/jquery-ui-1.8.5.custom.min.js]

Edit lib/form/doctrine/<your_module_name>Form.class.php to make use of the widgets you want. I’m interested in sfWidgetFormJQueryDate:

  public function configure()
  {
    $this->widgetSchema['created_at'] = new sfWidgetFormJQueryDate(array(
      'image' => '/images/silk_icons/calendar.png',
      'config' => '{}',
    ));
    $this->widgetSchema['updated_at'] = new sfWidgetFormJQueryDate(array(
      'image' => '/images/silk_icons/calendar.png',
      'config' => '{}',
    ));
  }

I have used the calendar.png icon from the famfamfam silk icon set. You can get the set here: http://www.famfamfam.com/lab/icons/silk/

I’ve used the date picker widget for filling in the created_at and updated_at fields. You can replace these values with the fields you need to manipulate in a user friendly way.

[Edit 17/10/2010:]
I’m not going mad, there is an issue with the ‘magic’ fields created_at and updated_at in that they have to be unset to become magic.
Found help here: http://levelx.me/technology/programming/symfony-1-4-doctrine-timestampable-behaviour/
Though the unset lines are better off being added just once to /lib/form/doctrine/BaseFormDoctrine.class.php, rather than each xxxForm.class.php file.
