How to create entity with Symfony2

Question

My general question is how to create entities and repositories with symfony2?

• How to create entity/repository with a schema.yml with doctrine orm? Where i must save schema.yml file? What are the commands to type in the console?
• I create a class entity without schema.yml what to do after? Command!?
• Where i must save my entity/repository file when entity is general for all the project or specific to a bundle?

My solutions (i don't know if it's good, best practice!?)

YML

Create "Entities.User.dcm.yml" file in HelloBundle/Resources/config/doctrine/metadata/orm with this code (by example):

Entities\User:
  type: entity
  table: users
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    name:
      type: string
      length: 50

Then

php app/console doctrine:mapping:import "HelloBundle" yml

php app/console doctrine:generate:entities "HelloBundle"

Then, you can test it in your controller with:

$user = new \Sensio\HelloBundle\Entity\User;
$user->setName('Acubens');
$em = $this->get('doctrine.orm.entity_manager');
$em->persist($user);
$em->flush();

or with PHP

Create "User.php" file in HelloBundle\Entity with this code

// Sensio/HelloBundle/Entity/User.php
namespace Sensio\HelloBundle\Entity;

/**
 * @orm:Entity
 */
class User
{
    /**
     * @orm:Id
     * @orm:Column(type="integer")
     * @orm:GeneratedValue(strategy="IDENTITY")
     */
    protected $id;

    /**
     * @orm:Column(type="string", length="255")
     */
    protected $name;
}

Then

php app/console doctrine:mapping:import "HelloBundle"

this will generate in "HelloBundle/Resources/config/doctrine/metadata/orm"

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
  <entity name="Sensio\HelloBundle\Entity\User" table="user">
    <change-tracking-policy>DEFERRED_IMPLICIT</change-tracking-policy>
    <id name="id" type="integer" column="id">
      <generator strategy="IDENTITY"/>
    </id>
    <field name="name" type="string" column="name" length="255"/>
    <lifecycle-callbacks/>
  </entity>
</doctrine-mapping>

Then delete User.php

php app/console doctrine:generate:entities "HelloBundle"

After you have a new nice file User.php

<?php

namespace Sensio\HelloBundle\Entity;

/**
 * Sensio\HelloBundle\Entity\User
 */
class User
{
    /**
     * @var string $name
     */
    private $name;

    /**
     * @var integer $id
     */
    private $id;


    /**
     * Set name
     *
     * @param string $name
     */
    public function setName($name)
    {
        $this->name = $name;
    }

    /**
     * Get name
     *
     * @return string $name
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * Get id
     *
     * @return integer $id
     */
    public function getId()
    {
        return $this->id;
    }
}

And you how do you do? Why i must specify HelloBundle in my commands?

ps: my config.yml

doctrine.dbal:
    driver:   pdo_mysql
    dbname:   sf2
    user:     root
    password: 
    logging:  %kernel.debug%
doctrine.orm:
    auto_generate_proxy_classes: %kernel.debug%
    mappings:
        HelloBundle: ~
