Symfony2 - 以字段形式映射对象的问题

Question

Objective 有一个 Perspective

class Objective{
    ...
    public function setPerspective(\Cboujon\BSCBundle\Entity\Pespective $perspective = null)
    {
        $this->perspective = $perspective;

        return $this;
    }
}

Objective.orm.yml

Cboujon\BSCBundle\Entity\Objective:
manyToOne:
        perspective:
            targetEntity: Perspective
            inversedBy: objectives
            joinColumn:
                name: perspective_id
                referencesColumn: id

ObjectiveType.php

 public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('perspective');
    }

Symfony2使用具有所有视角的组合框呈现一个表单.那没问题!但当我提交时,create form我收到错误:

ContextErrorException:Catchable Fatal Error:传递给Cboujon\BSCBundle\Entity \的参数1:Objective :: setPerspective()必须是Cboujon\BSCBundle\Entity\Pespective的实例,Cboujon\BSCBundle\Entity\Perspective的实例,在/ home中调用第376行的/cristhian/php_apps/Symfony/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php,在/home/cristhian/php_apps/Symfony/src/Cboujon/BSCBundle/Entity/Objective.php中定义第63行

注意:我也尝试:

        $builder->add('perspective', 'entity', array(
                'class' => 'CboujonBSCBundle:Perspective',
                )
              )
    ;

但我得到了同样的错误.

注意2:如果我\Cboujon\BSCBundle\Entity\Pespective从setPerspective定义中删除,我可以提交表单确定.

我究竟做错了什么？

Answer 1

在指定参数类型时,iThere是您的实体设置器中的拼写错误:

public function setPerspective(\Cboujon\BSCBundle\Entity\Pespective $perspective = null)
{
    $this->perspective = $perspective;

    return $this;
}

不是\ Cboujon\BSCBundle \实体\ 阈看,但\ Cboujon\BSCBundle \实体\ 视角
