SF4 - Doctrine migration not creating fields

[petegore]

Hi,

I followed the doc, but while running doctrine:migration:diff Doctrine tells me that no changes have been found in the DB schema.

I'm juste trying with the timestampable biehavior.
I installed the bundle and set the following configuration :

# config/stof_doctrine_extensions.yaml
stof_doctrine_extensions:
    default_locale: fr_FR
    orm:
        default:
            timestampable: true

Is there any incompatibiity with my doctrine.yaml file that doesn't have the default part ?

# config/doctrine.yaml
doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_mysql'
        server_version: '5.7'
        charset: utf8mb4

        # With Symfony 3.3, remove the `resolve:` prefix
        url: '%env(resolve:DATABASE_URL)%'
    orm:
        auto_generate_proxy_classes: '%kernel.debug%'
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App

Thanks !

[EDIT]

I tried to update my doctrine.yaml like this, but same issue :

# config/doctrine.yaml
doctrine:    
    orm:
        auto_generate_proxy_classes: '%kernel.debug%'
        default_entity_manager: default
        entity_managers:
            default:
                naming_strategy: doctrine.orm.naming_strategy.underscore
                auto_mapping: true
                mappings:
                    App:
                        is_bundle: false
                        type: annotation
                        dir: '%kernel.project_dir%/src/Entity'
                        prefix: 'App\Entity'
                        alias: App

Am I supposed to use Gedmo annotations ?

[EDIT 2]

I added the call to Gedmo trait into my entities and it works :

use Gedmo\Timestampable\Traits\TimestampableEntity;
```

Is it the right way ? If yes, a note about it could be added at the end of the doc.
