The config classes are defined in the application and bundles config directories, and they are defined in YAML_.
You must to use the standard namespace Model in the classes, thus the bundles will be reusable and coherent.
You don't need to use bundle namespace in your application classes:
# app/config/mandango/schema.yml Model\Article: fields: title: string content: string
In the bundles is necessary to use the bundle name to separate the classes by bundle:
# src/Mandango/MandangoUserBundle/Resources/config/mandango/schema.yml Model\MandangoUserBundle\User: fields: username: string password: string
The classes are generated in the src/Model directory, and the bundle classes extend of a bundle class before of the base class to be able to custom them in the bundles.
# application class Model\Article: Model\Base\Article # bundle class Model\MandangoUserBundle\User: Mandango\MandangoUserBundle\Model\User: Model\MandangoUserBundle\Base\User
To generate the classes is used the mandango:generate command:
php app/console mandango:generate
