问题描述
我正在使用Zend Framework 2,并创建了一个用户实体。现在我试图使用户名字段唯一。然而,以下错误即将出现。 [语义错误]类User \Entity\中的注释@UniqueEntity用户从未导入你可能忘了为这个注释添加一个使用语句?
我已经添加了此代码进行唯一性检查
@UniqueEntity(email)
我可以看到它是Symfony中使用的一种方法。如何使用Zend Framework 2?
这是我使用的实体
<?php
命名空间User\Entity;
使用Doctrine\ORM\Mapping作为ORM,
Zend\Form\Annotation;
/ **
*用户实体。
*
* @ ORM\Entity
* @ ORM\Table(name =users)
* @UniqueEntity(email)
* @property int $ id
* @property string $ username
* @property string $ email
* @property string $ password
*
* @Annotation \Name(User)
* /
class User {
/ **
* @ ORM\Id
* @ ORM\\ \\Column(类型= 整数);
* @ ORM\GeneratedValue(strategy =AUTO)
*
* @ Annotation\Required(false)
* /
protected $ id;
/ **
* @ ORM\Column(type =string)
*
* @ Annotation\Attributes({type:文本})
* @ Annotation\Options({label:Username:})
* @ Annotation\Filter({name:StringTrim})
* @ Annotation\Filter({name:StripTags})
* /
protected $ username;
/ **
* @ ORM\Column(type =string)

* @ Annotation\Options({label:Password:})
* @ Annotation\Filter({name:StringTrim})
* @ Annotation\Filter({name:StripTags})
* /
protected $ password;
public function __get($ property){
return $ this-> $ property;
}
/ **
* Magic setter保存受保护属性。
*
* @param string $ property
* @param mixed $ value
* /
public function __set($ property,$ value){
$ this-> $ property = $ value;
}
public function getArrayCopy(){
return array(
'username'=> $ this-> username,
'email' => $ this-> email,
'surname'=> $ this-> surname,
'first_name'=> $ this-> first_name,
'company '=> $ this-> company,
'postcode'=> $ this->邮政编码,
);
}
public function populate($ data){
$ this-> username = isset($ data ['username'])? $ data ['username']:$ this-> username;
}
public function setDate($ property,$ value){
$ this-> $ property = new \DateTime($ value);
}
}
是一个symfony验证组件的特殊扩展(在这里写为注释),
@UniqueEntity
您正在寻找的可能是您可以在 DoctrineModule
中找到的验证器:
支持它作为注释尚未内置。
I am using Zend Framework 2 and I have created a User Entity. Now I am trying to make the username field unique. However the following error is coming up.
[Semantical Error] The annotation "@UniqueEntity" in class User\Entity\User was never imported. Did you maybe forget to add a "use" statement for this annotation?
I have added this code for uniqueness check
@UniqueEntity("email")
I can see that it is a method used in Symfony. How can I use it for Zend Framework 2?
This is the Entity I am using
<?php
namespace User\Entity;
use Doctrine\ORM\Mapping as ORM,
Zend\Form\Annotation;
/**
* A user entity.
*
* @ORM\Entity
* @ORM\Table(name="users")
* @UniqueEntity("email")
* @property int $id
* @property string $username
* @property string $email
* @property string $password
*
* @Annotation\Name("User")
*/
class User {
/**
* @ORM\Id
* @ORM\Column(type="integer");
* @ORM\GeneratedValue(strategy="AUTO")
*
* @Annotation\Required(false)
*/
protected $id;
/**
* @ORM\Column(type="string")
*
* @Annotation\Attributes({"type":"text"})
* @Annotation\Options({"label":"Username:"})
* @Annotation\Filter({"name":"StringTrim"})
* @Annotation\Filter({"name":"StripTags"})
*/
protected $username;
/**
* @ORM\Column(type="string")
*
* @Annotation\Attributes({"type":"text" })
* @Annotation\Options({"label":"Email:"})
* @Annotation\Filter({"name":"StringTrim"})
* @Annotation\Filter({"name":"StripTags"})
*/
protected $email;
/**
* @ORM\Column(type="string")
*
* @Annotation\Attributes({"type":"text" })
* @Annotation\Options({"label":"Password:"})
* @Annotation\Filter({"name":"StringTrim"})
* @Annotation\Filter({"name":"StripTags"})
*/
protected $password;
public function __get($property) {
return $this->$property;
}
/**
* Magic setter to save protected properties.
*
* @param string $property
* @param mixed $value
*/
public function __set($property, $value) {
$this->$property = $value;
}
public function getArrayCopy() {
return array(
'username' => $this->username,
'email' => $this->email,
'surname' => $this->surname,
'first_name' => $this->first_name,
'company' => $this->company,
'postcode' => $this->postcode,
);
}
public function populate($data) {
$this->username = isset($data['username']) ? $data['username'] : $this->username;
}
public function setDate($property, $value){
$this->$property = new \DateTime($value);
}
}
@UniqueEntity
is a particular extension of the symfony validation component (written as annotation here). What you are looking for is probably the validators you can find in DoctrineModule
: https://github.com/doctrine/DoctrineModule/blob/master/docs/validator.md
Support for it as annotation is not yet built-in.
