在Symfony中,我创建了一个实体:
src / Entity / User.php
<?php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
/**
* @ORM\Table(name="app_users")
* @ORM\Entity(repositoryClass="App\Repository\UserRepository")
*/
class User implements UserInterface, \Serializable
{
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\Column(type="string", length=25, unique=true)
*/
private $username;
/**
* @ORM\Column(type="string", length=64)
*/
private $password;
/**
* @ORM\Column(type="string", length=254, unique=true)
*/
private $email;
/**
* @ORM\Column(name="is_active", type="boolean")
*/
private $isActive;
public function __construct()
{
$this->isActive = true;
// may not be needed, see section on salt below
// $this->salt = md5(uniqid('', true));
}
public function getUsername()
{
return $this->username;
}
public function getSalt()
{
// you *may* need a real salt depending on your encoder
// see section on salt below
return null;
}
public function getPassword()
{
return $this->password;
}
public function getRoles()
{
return array('ROLE_USER');
}
public function eraseCredentials()
{
}
/** @see \Serializable::serialize() */
public function serialize()
{
return serialize(array(
$this->id,
$this->username,
$this->password,
// see section on salt below
// $this->salt,
));
}
/** @see \Serializable::unserialize() */
public function unserialize($serialized)
{
list (
$this->id,
$this->username,
$this->password,
// see section on salt below
// $this->salt
) = unserialize($serialized, ['allowed_classes' => false]);
}
}
之后,我想通过终端创建数据库表:
php bin/console doctrine:migrations:diff
php bin/console doctrine:migrations:migrate
但是我收到很多错误消息:

答案 0 :(得分:1)
/**
* @ORM\Column(type="string", length=254, unique=true)
*/
private $email;
更改为最大长度191(应该足以容纳电子邮件...)
/**
* @ORM\Column(type="string", length=191, unique=true)
*/
private $email;
或更改您的存储引擎...
