我有几个实体,我尝试设置用户和权限之间的关系。我希望有可能为用户分配权限组,因此我创建了实体User,GroupAssociationsUser,Permissions。我认为最好的方法是在GroupAssociationsUser中为用户和权限创建关系ManyToOne。您可以看到GroupAssociationsUser实体的代码:
/**
* @ORM\ManyToOne(targetEntity="Permissions", inversedBy="group_assoc_user")
* @ORM\JoinColumn(name="group_permissions", referencedColumnName="id", nullable=FALSE)
*/
private $group_permissions;
/**
* @ORM\ManyToOne(targetEntity="User", inversedBy="group_assoc_user")
* @ORM\JoinColumn(name="user_assoc", referencedColumnName="id", nullable=FALSE)
*/
private $user_assoc;
然后我还在用户实体中创建了关系:
/**
* @ORM\OneToMany(targetEntity="GroupAssociationsUser", mappedBy="user_assoc")
*/
private $group_assoc_user;
public function __construct()
{
$this->group_assoc_user = new ArrayCollection();
}
最后在Permission实体中:
/**
* @ORM\OneToMany(targetEntity="GroupAssociationsUser", mappedBy="group_permissions")
*/
private $group_assoc_user;
public function __construct()
{
$this->group_assoc_user = new ArrayCollection();
}
所以基本上我想在我的用户编辑页面上选择列表,我希望有可能选择要分配给用户的权限组。
所以我用:
创建了表单->add('group_assoc_user', EntityType::class, array(
'class' => 'AppBundle:Permissions',
'choice_label'=> 'group_name',
'placeholder' => 'no rights',
))
问题在于,无论我做什么,我只有现有权限列表,或者如果我将代码更改为:
->add('group_assoc_user', EntityType::class, array(
'class' => 'AppBundle:GroupAssociationsUser',
'choice_label'=> 'Permissions.group_name',
'placeholder' => 'no rights',
));
我只列出了未分配的分配权限。我究竟做错了什么?
即使我获得了所有权限名称,我如何强制学说标记已分配的字段?

尝试将Multiple设置为true。

->add('group_assoc_user', EntityType::class, array(
'class' => 'AppBundle:GroupAssociationsUser',
'choice_label'=> 'Permissions.group_name',
'placeholder' => 'no rights',
'multiple' => true,
));

'expanded' => true
