Postモデルの作成
今回は、Doctrineを利用したモデルの作成

【モデルの作成】

generate:dctrine:entityコマンドで、モデルを生成

モデルの生成

$ php app/console generate:doctrine:entity –entity=MyBlogBundle:Post –format=annotation –fields=”title:string(255) body:text createdAt:datetime updatedAt:datetime”

生成結果

datetime updatedAt:datetime”
Xdebug requires Zend Engine API version 220060519.
The Zend Engine API version 220090626 which is installed, is newer.
Contact Derick Rethans at http://xdebug.org/docs/faq#api for a later version of Xdebug.

Welcome to the Doctrine2 entity generator

This command helps you generate Doctrine2 entities.

First, you need to give the entity name you want to generate.
You must use the shortcut notation like AcmeBlogBundle:Post.

The Entity shortcut name [MyBlogBundle:Post]:

Determine the format to use for the mapping information.

Configuration format (yml, xml, php, or annotation) [annotation]:

Instead of starting with a blank entity, you can add some fields now.
Note that the primary key will be added automatically (named id).

Available types: array, object, boolean, integer, smallint,
bigint, string, text, datetime, datetimetz, date, time, decimal, float.

New field name (press to stop adding fields):

Do you want to generate an empty repository class [no]?

Summary before generation

You are going to generate a “MyBlogBundle:Post” Doctrine2 entity
using the “annotation” format.

Do you confirm generation [yes]?

Entity generation

Generating the entity code: OK

You can now start using the generated code!

生成されたPost.php

$ vim src/My/BlogBundle/Entity/Post.php

<?php

namespace My\BlogBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
* My\BlogBundle\Entity\Post
*
* @ORM\Table()
* @ORM\Entity
*/
class Post
{
/**
* @var integer $id
*
* @ORM\Column(name=”id”, type=”integer”)
* @ORM\Id
* @ORM\GeneratedValue(strategy=”AUTO”)
*/
private $id;

/**
 * @var string $title
 *
 * @ORM\Column(name="title", type="string", length=255)
 */
private $title;

/**
 * @var text $body
 *
 * @ORM\Column(name="body", type="text")
 */
private $body;

/**
 * @var datetime $createdAt
 *
 * @ORM\Column(name="createdAt", type="datetime")
 */
private $createdAt;

/**
 * @var datetime $updatedAt
 *
 * @ORM\Column(name="updatedAt", type="datetime")
 */
private $updatedAt;


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

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

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

/**
 * Set body
 *
 * @param text $body
 */
public function setBody($body)
{
    $this->body = $body;
}

/**
 * Get body
 *
 * @return text
 */
public function getBody()
{
    return $this->body;
}

/**
 * Set createdAt
 *
 * @param datetime $createdAt
 */
public function setCreatedAt($createdAt)
{
    $this->createdAt = $createdAt;
}

/**
 * Get createdAt
 *
 * @return datetime
 */
public function getCreatedAt()
{
    return $this->createdAt;
}

/**
 * Set updatedAt
 *
 * @param datetime $updatedAt
 */
public function setUpdatedAt($updatedAt)
{
    $this->updatedAt = $updatedAt;
}

/**
 * Get updatedAt
 *
 * @return datetime
 */
public function getUpdatedAt()
{
    return $this->updatedAt;
}

}

【スキーマの生成】

先ほど生成されたエンティティクラスのアノテーションに記載されたフィールド情報を元に、スキーマを生成

スキーマ生成

$ php app/console doctrine:schema:create
