For Q&A

• I need a group of users to access only some specific apps. How can I do that?+

  You can control access to apps by listing a user role under the permissions node in the configuration of an app (see App permissions).

  The permission to use an app can also be specified under the permissions node in the app descriptor when developing the app. This allows you to provision the app to certain users in your organization. For further details, see Permissions and Groups.

• I would like to change an existing definition. How can I do that?+

  To change an existing definition, use the Definitions app to find and highlight the definition. In the action bar, you will see Show in Resources app or Show in Configuration app depending on the definition type. Click the action and edit the definition in the target location.

  In the Resource Files app, you can fix the definition in the app or edit it on the file system.

  In the Configuration app, you can edit the definition in the JCR.

  For more information, see Resource Files app and Configuration app.

  You can also change an existing definition by decorating it. For more details, see Definition decoration.

• What are version handlers, and when should I use one?+

  A version handler is a Java class used to update the JCR during a module upgrade. It should be used to change any configuration that may have been bootstrapped during the initial installation or previous upgrade.

  The related interface is info.magnolia.module.ModuleVersionHandler, which contains a series of tasks (deltas) executed during installation or during specific updates.

  If your module needs to handle its own installation and updates you should provide an implementation of this interface.
