Doctrine のリバース エンジニアリング プロセスの奇妙な動作を見つけました。単純な 1 対 n の関係で結び付けられた 2 つの単純なテーブルを作成するだけです。次の SQL コードのスナップを見てください。

SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL';

DROP SCHEMA IF EXISTS `ACME` ;
CREATE SCHEMA IF NOT EXISTS `ACME` DEFAULT CHARACTER SET latin1 COLLATE latin1_swedish_ci ;
USE `ACME` ;

-- -----------------------------------------------------
-- Table `ACME`.`task`
-- -----------------------------------------------------
DROP TABLE IF EXISTS `ACME`.`task` ;

CREATE  TABLE IF NOT EXISTS `ACME`.`task` (
  `id_task` INT UNSIGNED NOT NULL AUTO_INCREMENT ,
  `description` VARCHAR(45) NULL ,
  PRIMARY KEY (`id_task`) )
ENGINE = InnoDB;


-- -----------------------------------------------------
-- Table `ACME`.`tag`
-- -----------------------------------------------------
DROP TABLE IF EXISTS `ACME`.`tag` ;

CREATE  TABLE IF NOT EXISTS `ACME`.`tag` (
  `id_tag` INT UNSIGNED NOT NULL AUTO_INCREMENT ,
  `name` VARCHAR(50) NULL ,
  `task_id` INT UNSIGNED NOT NULL ,
  PRIMARY KEY (`id_tag`) ,
  INDEX `fk_tag_task` (`task_id` ASC) ,
  CONSTRAINT `fk_tag_task`
    FOREIGN KEY (`task_id` )
    REFERENCES `ACME`.`task` (`id_task` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;



SET SQL_MODE=@OLD_SQL_MODE;
SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS;
SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS;

私は Symfony2 netbeans プロジェクトを持っています

/Applications/MAMP/htdocs/Acme

そしてその場所から、

http://symfony.com/doc/current/cookbook/doctrine/reverse_engineering.html

私がした端末で:

$ ./../../bin/php/php5.3.6/bin/php app/console doctrine:mapping:convert yml ./src/Acme/TaskBundle/Resources/config/doctrine/ --from-database --force

「Tag.orm.yml」を見ると、問題ないように見えるのは事実です。

Acme\TaskBundle\Entity\Tag:
  type: entity
  table: tag
  fields:
    idTag:
      id: true
      type: integer
      unsigned: false
      nullable: false
      column: id_tag
      generator:
        strategy: IDENTITY
    name:
      type: string
      length: 50
      fixed: false
      nullable: true
  oneToOne:
    task:
      targetEntity: Task
      cascade: {  }
      mappedBy: null
      inversedBy: null
      joinColumns:
        task_id:
          referencedColumnName: id_task
      orphanRemoval: false
  lifecycleCallbacks: {  }

oneToManyではなく、 oneToOne関係を作成しました。

さらに確認が必要な場合は、Task.phpTag.phpを次に示します。

Task.php

namespace Acme\TaskBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Acme\TaskBundle\Entity\Task
 */
class Task
{
    /**
     * @var integer $idTask
     */
    private $idTask;

    /**
     * @var string $description
     */
    private $description;


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

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

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

タグ.php

namespace Acme\TaskBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Acme\TaskBundle\Entity\Tag
 */
class Tag
{
    /**
     * @var integer $idTag
     */
    private $idTag;

    /**
     * @var string $name
     */
    private $name;

    /**
     * @var Acme\TaskBundle\Entity\Task
     */
    private $task;


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

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

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

    /**
     * Set task
     *
     * @param Acme\TaskBundle\Entity\Task $task
     */
    public function setTask(\Acme\TaskBundle\Entity\Task $task)
    {
        $this->task = $task;
    }

    /**
     * Get task
     *
     * @return Acme\TaskBundle\Entity\Task 
     */
    public function getTask()
    {
        return $this->task;
    }
}

皆さんもこの問題に遭遇しましたか?
