symfony 2 - 一对一映射

Question

我收到以下错误，当我想要使用自动生成的表单添加新的UserProfile时。错误是： 预期的对象，但有一个集合。你忘了将“multiple = true”传递给实体字段吗？

我使用Symfony的2.0.12

这是我的用户配置实体代码。问题发生在Controller中，但我不知道如何解决它。请帮忙。

Answer 1

问题出在你的形式上... 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'); }, 

} 

Answer 2

当嵌入另一种形式的一种形式，则需要通过设置用户类型:: getDefaultOptions（该data_class选项，什么类型的对象的嵌入形式映射申报）。

查看http://symfony.com/doc/current/book/forms.html#embedding-a-single-object举例。
