我使用 FOSUserBundle 和“组”功能

起初在我的 User.php 中有这样的 getter 和 setter

/**
 * Add groups
 *
 * @param \Acme\UserBundle\Entity\Group $groups
 * @return User
 */

public function addGroup(\Acme\UserBundle\Entity\Group $groups)
{
    $this->groups[] = $groups;

    return $this;
}

/**
 * Remove groups
 *
 * @param \Acme\UserBundle\Entity\Group $groups
 */
public function removeGroup(\Acme\UserBundle\Entity\Group $groups)
{
    $this->groups->removeElement($groups);
}

/**
 * Get groups
 *
 * @return \Doctrine\Common\Collections\Collection
 */
public function getGroups()
{
    return $this->groups;
}

但是，这个错误发生

FatalErrorException: Compile Error: Declaration of Acme\UserBundle\Entity\User::addGroup() must be compatible with that of FOS\UserBundle\Model\GroupableInterface::addGroup()

在 FOS\UserBundle\Model\GroupableInterface

public function addGroup(GroupInterface $group);

在我的 Acme\UserBundle\Entity\User

public function addGroup(\Acme\UserBundle\Entity\Group $groups)
{
    $this->groups[] = $groups;

    return $this;
}


如何调整参数类型或更正此错误？


目前，我已经注释掉了这三个函数。

当时它看起来运作良好。

但是现在，我使用 Sonataadmin bundle 并在

@SonataAdminBundle/Admin/UserAdmin.php

protected function configureFormFields(FormMapper $formMapper){
    $formMapper
      ->with('General')
      ->add('groups','entity',array('property' => 'name',
              'multiple' => true,
              'class' => 'UserBundle:Group',
      ))
}

它正确显示了此表单，但是当我按下提交按钮进行注册时，

表明

Error: Call to a member function contains() on a non-object in ~~~/FOS/UserBundle/Model/User.php line 572

在 /FOS/UserBundle/Model/user.php 中有这样的功能

public function addGroup(GroupInterface $group)
{  
   var_dump($group);# I added to check
   if (!$this->getGroups()->contains($group)) {
        $this->getGroups()->add($group);
    }
    return $this;
}

var_dump($group) 显示

object(Acme\UserBundle\Entity\Group)#923 (3) { ["id":protected]=> int(2) ["name":protected]=> string(12) "TeacherGroup" ["roles":protected]=> array(0) { } }

我猜它有正确的组信息..

我该如何解决这个问题？

问题是您getGroups()像这样覆盖：

/**
 * Get groups
 *
 * @return \Doctrine\Common\Collections\Collection 
 */
public function getGroups()
{
    return $this->groups;
}

但是你从来没有初始化$this->groups，所以当你调用时$this->getGroups()->contains()，它说那$this->getGroups()是 a non-object，这是真的！

要解决这个问题，您有 2 个解决方案。

groups您可以在以下构造函数中进行初始化User：

public function __construct()
{
    parent::__construct();

    &this->groups = new ArrayCollection();
}

或者，如果尚未初始化，您可以更改getGroups()函数以返回新对象：groups

public function getGroups()
{
    return $this->groups ?: $this->groups = new ArrayCollection();
}

在这两种情况下，不要忘记use Doctrine\Common\Collections\ArrayCollection;在开头添加User.php.

我得到了同样的错误：

FatalErrorException: Compile Error: Declaration of Acme\UserBundle\Entity\User::addGroup() must be compatible with that of FOS\UserBundle\Model\GroupableInterface::addGroup()

经过搜索，我发现（FOS Git Issue 988）这个特殊错误是一个 Doctrine 'Bug' 或 sth。

Doctrine 根本不应该生成该方法，因为在基类中有 addGroup() 的实现。我通过修改签名来解决它

public function addGroup(\MyBundleNamespace\Entity\Group $groups)
public function removeGroup(\MyBundleNamespace\Entity\Group $groups)

到

public function addGroup(\FOS\UserBundle\Model\GroupInterface $groups)
public function removeGroup(\FOS\UserBundle\Model\GroupInterface $groups)

这样你就可以防止 Doctrine 使用错误的签名生成这两个函数。

版本信息：

Symfony       2.2.1
DoctrineORM   2.2.3
FOSUserBundle 1.3.1
PHP           5.4.4-14

也许这可以帮助别人！

我遇到了这个问题，简单的解决方案是将groups变量的声明从public更改为protected：

 /**
  * @var \Doctrine\Common\Collections\Collection
  */
 protected $groups;

解决方案很简单：在您自己的 userBundle 中从您自己的实体中删除所有 setter 和 getter，并始终为特定捆绑运行教义：生成：实体，而不是全部。
