Symfony's Command : No default connection - php

Question

In my Symfony2 project, I need to do some work in database with a Command.
When I launch it, I have this error :
[Exception]
There is no default connection
I don't understand why ?
My code :
1. $this->output = $output;
2. $this->writeln( 'ImportBase' );
3. $importBase = Model\ImportBase::builder()
->whereEgal('termine', 0)
->limit(1)
->getObject();
For information, there is just one connection in my project.
Also, I do not use Doctrine but ORM (I guess ? This is not my project)
Do you have any idea ? I can't find anything...
EDIT :
config.yml :
doctrine:
dbal:
default_connection: default
connections:
default:
driver: "%database_driver%"
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
charset: UTF8
orm:
auto_generate_proxy_classes: "%kernel.debug%"
auto_mapping: true
Parameters.yml
parameters:
database_driver: pdo_mysql
database_host: 127.0.0.1
database_port: null
database_name: [...]
database_user: [...]
database_password: [...]
Model :
<?php
namespace xxx\xxxhBundle\Model;
use xxx\ORM\Model;
class ImportBase extends Model
{
protected static $table_name = 'import_base';
protected static $primary_key = 'import_base_id';
}
Builder in Model file
/**
* Get command builder for the class
*
* #return DbCommandBuilder builder
*/
public static function builder() {
if( static::$table_name == null )
throw new \Exception('Canot get builder, table_name is not set');
$builder = static::dbConnection()->builder( static::tableName(), static::$builder_class );
$builder->setFetchClassName( get_called_class() );
return $builder;
}

That seems a little strange... I don't notice anything wrong based on the configuration you've supplied.
However, since you appear to only have one dbal connection, you could simply use the "terser" configuration:
doctrine:
dbal:
driver: "%database_driver%"
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%
charset: UTF8
orm:
auto_generate_proxy_classes: "%kernel.debug%"
auto_mapping: true
Hope this helps :)
