无法创建带日期的固定装置

Can't create fixtures with dates

我有以下用户实体和夹具文件,但是当我 运行 app/console doctrine:fixtures:load 时,我得到以下错误并且不确定为什么。如果我删除日期字段,则灯具会正常生成。我在这里错过了什么?谢谢

错误:无法确定如何将 created_at 分配给 AppBundle\Entity\User 对象

<?php

namespace AppBundle\Entity;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;

/**
 * User
 *
 * @ORM\Table()
 * @ORM\Entity(repositoryClass="AppBundle\Entity\UserRepository")
 */
class User
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

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

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

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

    /**
     * @var string
     *
     * @ORM\Column(name="phone", type="string", length=16)
     */
    private $phone;

    /**
     * @var \DateTime
     *
     * @Gedmo\Timestampable(on="create")
     * @ORM\Column(name="created_at", type="datetime", nullable=true)
     */
    private $createdAt;

    /**
     * @var \DateTime
     *
     * @Gedmo\Timestampable(on="update")
     * @ORM\Column(name="updated_at", type="datetime", nullable=true)
     */
    private $updatedAt;

还有我的夹具 yml:

AppBundle\Entity\User:
user{1..10}:
    name: <firstName()> <lastName()>
    role: employee
    email: <email()>
    phone: <numberBetween(1555000000, 1555999999)>
    created_at: <datetimeBetween('-5 days', 'now')>
    updated_at: <datetimeBetween('-5 days', 'now')>

恐怕您无法手动设置时间戳字段。在 documentation and entity example 中,此类字段根本没有设置器。所以在固定装置中你可以简单地删除 created_atupdated_at (它们将自动设置):

ppBundle\Entity\User:
user{1..10}:
    name: <firstName()> <lastName()>
    role: employee
    email: <email()>
    phone: <numberBetween(1555000000, 1555999999)>

不确定,但我认为命名不正确,只是错误的意思。我觉得应该是:

createdAt: <datetimeBetween('-5 days', 'now')>
updatedAt: <datetimeBetween('-5 days', 'now')>
