Symfony2:在 FormBuilder 中获取用户角色列表 [英] Symfony2: Getting the list of user roles in FormBuilder

问题描述

我正在制作一个用于创建用户的表单，我想在创建用户时为其分配一个或多个角色.

I'm making a form for user creation, and I want to give one or several roles to a user when I create him.

如何获取security.yml中定义的角色列表?

How do I get the list of roles defined in security.yml?

这是我目前的表单构建器:

Here's my form builder at the moment:

public function buildForm(FormBuilder $builder, array $options)
{
    parent::buildForm($builder, $options);

    // add your custom fields
    $user = new User();
    $builder->add('regionUser');
    $builder->add('roles' ,'choice' ,array('choices' => $user->getRolesNames(),
            'required'  => true,
    ));

}

并在 User.php 中

and in User.php

public function getRolesNames(){
    return array(
        "ADMIN" => "Administrateur",
        "ANIMATOR" => "Animateur",
        "USER" => "Utilisateur",        
    );
}

当然，这个方案是行不通的，因为roles在数据库中被定义为位图，所以无法创建choices列表.

Of course, this solution doesn't work, because roles is defined as a bitmap in the database, therefore the choices list cannot be created.

提前致谢.

推荐答案

security.role_hierarchy.roles 容器参数将角色层次结构保存为数组.您可以对其进行概括以获取定义的角色列表.

security.role_hierarchy.roles container parameter holds the role hierarchy as an array. You can generalize it to get list of roles defined.
