How to use horde shares in your custom application

work in progress

Let's assume you followed the Creating your first module guide as far as it applies to horde4 and created a new horde app called "hort". Hort is an old German word for treasure as well as the place where the treasure is kept. Hort should keep safes which hold user/password pairs or other secret credentials. Those safes should be shareable among users. This is where horde_shares comes into play.

basic setup in Application.php _init()

We want to add an injector for the shares API whenever the app is initialized and we want to auto-create an initial "home" share for users which do not yet own one.

    protected function _init()
    {
        // Create a share instance.
        $GLOBALS['hort_shares'] = $GLOBALS['injector']->getInstance('Horde_Core_Factory_Share')->create();

        /* If the user doesn't own a safe, create one. */
        if (!empty($GLOBALS['conf']['share']['auto_create']) &&
            $GLOBALS['registry']->getAuth() &&
            !$GLOBALS['hort_shares']->countShares($GLOBALS['registry']->getAuth())) {
            $identity = $GLOBALS['injector']->getInstance('Horde_Core_Factory_Identity')->create();
            $share = $GLOBALS['hort_shares']->newShare(
                $GLOBALS['registry']->getAuth(),
                strval(new Horde_Support_Randomid()),
                sprintf(_("Default safe of %s"), $identity->getName())
            );
            $GLOBALS['hort_shares']->addShare($share);
        }

    }

List of safes in Application.php menu()

Next we want to add a page with a list of safes (shares) in the menu.
Go to the menu() function in Application.php

        $menu->add(Horde::url('safes.php'), _("Password Safes"), 'user.png');

migrations script (database setup) for shares and sharesng driver tables

Create a directory hort/migrations/ with a file 1_hort_tables.php

class HortBaseTables extends Horde_Db_Migration_Base
{
    /**
     * Upgrade.
     */
    public function up()
    {
