Php symfony 2-一对一映射

当我想使用自动生成的表单添加新的UserProfile时，出现以下错误。错误为： 需要一个对象，但得到了一个集合。是否忘记将“multiple=true”传递给实体字段？

我正在使用Symfony 2.0.12

这是我的UserProfile实体代码。控制器出现问题，但我不确定如何解决。请帮忙

在另一个表单中嵌入表单时，需要通过在UserType:：getDefaultOptions（）中设置data_class选项来声明嵌入表单映射到的对象类型

请参阅以获取示例。

问题在您的表单中。。。
试试这个

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


        $builder
->add('employeeType', 'entity', array(
                    'class' => 'MyProject\EntityBundle\Entity\Employee',
                    'property' => 'name',
                      'multiple'=>'true','query_builder' => function ($repository) { return $repository->createQueryBuilder('es')->orderBy('es.name', 'ASC'); },

}

问题出在你身上。。。

}

为我工作。因为这是一对一的关系，所以multiple不应该是真的。我还从UserProfile中删除了构造函数。谢谢，为我工作。因为这是一对一的关系，所以multiple不应该是真的。我还从UserProfile中删除了构造函数。谢谢
