PHP学习过程_Symfony_(4)_命令创建实体_以及实体关系

//项目运行

php app/console server:run

//创建实体
php app/console doctrine:generate:entity

bundle名称:实体名称

//实体添加ORM和Assert
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

//同步数据库
php app/console doctrine:schema:update --force

//自动创建增删该查
php app/console generate:doctrine:crud

//关联关系创建:
对应的yml中添加多对一的关系
    manyToOne:
        category:
            targetEntity: PhotoCategory--一端实体名称
            inversedBy: photos
            joinColumn:
                name: photocategory_id--多端对应的实体字段
                referencedColumnName: id

实体中ORM
    /**
     * @ORM\ManyToOne(targetEntity="PhotoCategory", inversedBy="photos")
     * @ORM\JoinColumn(name="photocategory_id", referencedColumnName="id")
     */
   private $category;

//生成geter,seter
php app/console doctrine:generate:entities AcmeStoreBundle
