父窗体中没有包含Symfony子窗体属性

Question

所以我有麻烦从子表单获取属性。这个场景是我制作了一个Work表单，其中选择了"雇主"。如果用户是应用程序管理员，他们可以选择所有雇主。如果用户是为多个雇主工作的员工，他们将在表单中选择雇主。否则(如果它们只有一个雇主)，我想用雇主集呈现一个隐藏字段。此外，Employer子表单应该自己处理这个问题。

我的策略是在雇主子表单中设置一些属性，但是当我将这些属性添加到工作表单时，它们没有通过(特别是'value')。

有人知道我如何传播这些属性吗?

非常有趣的代码格式，但很难阅读。乍一看，这里的错误似乎是

'query_builder' =>
                function ( $repository ) {
                    $qb = $repository->createQueryBuilder( 'b' )
                    ->addOrderBy( 'b.name' );
                    if ( ! $this->usor->isAdmin() ) {
                        $qb->join( 'b.usor', 'u' )->andWhere( "u=$this->usor" );
                    }
                    return $qb;
                }

您使用闭包作为回调函数，因此需要使用use关键字为闭包提供上下文。

'query_builder' => function ( $repository ) use ($usor) {
    $qb = $repository
        ->createQueryBuilder( 'b' )
        ->addOrderBy( 'b.name' );
    if ( ! $usor->isAdmin() ) {
        $qb->andWhere('b.usor = :u')->setParameter('u', $usor);
    }
    return $qb;
}
