问题描述

我有自己的User类，它继承了FOS\UserBundle\Entity\User.此外，我写了自己的注册例程.现在，我有一个问题，即该表单无法确保用户名是唯一的.我总是得到:

sqlState [23000]:违规的完整性约束:1062重复输入'myusername'for键'uniq_2da1797792fc23a8'

我尝试添加文档中所述的@UniqueEntity("email")注释，推荐答案

约束已经存在于FOS捆绑包中.您可能需要将表单上的validation_groups选项设置为array('Registration').

要实现它，只需确保您的用户类构成适当的使用语句，然后像这样的注释(假设您使用注释):

<?php
// ...
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")
 * @UniqueEntity("email")
 * @UniqueEntity("username")
*/
class User extends BaseUser
{ /* ... */ }

其他推荐答案

您可以在用户实体验证的情况下在validation.yml上尝试一下:

constraints:    
    - FOS\UserBundle\Validator\Unique:
        property: usernameCanonical
        message:  'This username already exists. Please choose another one.'

问题描述

I have my own User Class, which inherits FOS\UserBundle\Entity\User. Additionally I wrote my own registration routine. Now I have the problem that the form does not make sure that the username is unique. I always get:

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'myusername' for key 'UNIQ_2DA1797792FC23A8'

I tried adding the @UniqueEntity("email") annotation as stated in the documentation1, but without any effect.

Someone knows what might be wrong?

If you're using the fos_user bundle, you can simply use the UniqueEntity constraint: http://symfony.com/doc/2.0/reference/constraints/UniqueEntity.html.

To implement it, just make sure your User class constains the proper use statements, and then the annotations, like so (assuming you're using annotations):

<?php
// ...
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")
 * @UniqueEntity("email")
 * @UniqueEntity("username")
*/
class User extends BaseUser
{ /* ... */ }

其他推荐答案

You can try this on the validation.yml with your user entity validation:

constraints:    
    - FOS\UserBundle\Validator\Unique:
        property: usernameCanonical
        message:  'This username already exists. Please choose another one.'
