Symfony 表单继承:属性和方法都不存在 [英] Symfony form inheritance : Neither the property nor one of the methods exist

问题描述

我有一个嵌套表单

demand
    home
       child
       godfather

demand 是一个父元素并嵌入了 home ，它嵌入了 child 和 father (最后两个表单在同级)

demand is a parent and embed home which embed child and father (2 last forms are on the same level)

在 DemandeType 我有:

           $builder
           ->add('date', 'datetype')
           ->add('name', 'text')
           //...

           ->add('home', 'home', array(
            'mapped' => false,
            'data_class' => 'AppBundle\Entity\Home',
            'inherit_data' => true
             ))

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'AppBundle\Entity\Demand',
    ));
}

在 HomeType 中:

           $builder
           ->add('address', 'textarea')
           //...

           ->add('child', 'child', array(
            'mapped' => false,
            'data_class' => 'AppBundle\Entity\Child',
            'inherit_data' => true
             ))

           ->add('godfather', 'godfather', array(
            'mapped' => false,
            'data_class' => 'AppBundle\Entity\Godfather',
            'inherit_data' => true
             ))

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'AppBundle\Entity\Home',
    ));
}

在 ChildType 和 GodfatherType 中，我只有名字和姓氏的文本字段，以及正确的 data_class.

And in ChildType and GodfatherType I have only text fields for firstname, lastname with their right data_class.

但是当我提交表单(DemandType，嵌入所有子表单)时，我收到了这个错误:

But when I submit the form (DemandType, wichh embed all subforms) I got this error :

属性address"和方法getAddress()"、address()"、isAddress()"、hasAddress()"、__get()"都不存在并且在类中具有公共访问权限AppBundle\实体\需求".

Neither the property "address" nor one of the methods "getAddress()", "address()", "isAddress()", "hasAddress()", "__get()" exist and have public access in class "AppBundle\Entity\Demand".

而且这些方法不属于Demand 实体，而是Home 实体.我已经输入了 inherit_data，我缺少什么?

And these methods don't belong to Demand entity but Home entity. I've put the inherit_data, what I'm missing ?

谢谢

推荐答案

发生这种情况是因为您正在使用 inherit_data.此属性使表单将整个提交的数据传递给其子项，而不是默认情况下发生的单个属性(或来自 getter 函数的任何内容).

This happens because you're using inherit_data. This property makes the form pass the entire submitted data to its child instead of a single property (or anything from getter function) which happens by default.

您为 demand 和 home 执行此操作，这就是 home 表单类型接收实例 Demand 实体的原因.所以我猜你想从 home 中删除 inherit_data 并使用:

You do this for both demand and home so that's why home form type receives an instance Demand entity. So I guess you want to remove inherit_data from home and use just:

->add('home', 'home', array(
    'mapped' => false,
    'data_class' => 'AppBundle\Entity\Home',
))

在这种情况下，home 将从 $demand->getHome() 接收数据，该数据应该是一个 Hone 实体.

In this case home will receive data from $demand->getHome() which should be a Hone entity.

我不确定您是否真的需要使用 inherit_data，但这取决于您的用例.通常，您不需要它，因为您有实体结构，例如:

I'm not sure you really need to use inherit_data at all but depends on your use case. Usually, you don't need it because you have structure of entities such as:

/** @ORM\Entity() */
class Demand {
    /** @ORM\OneToWhatever() */
    private $home;
    public function getHome() {
        return $this->home;
    }
}

/** @ORM\Entity() */
class Home {
    /** @ORM\OneToWhatever() */
    private $child;
    public function getChild() {
        return $this->child;
    }
}

/** @ORM\Entity() */
class Child { ... }

但我不知道你的数据结构到底是什么，所以很难提供帮助.

But I don't know what exactly your data structure is so it's hard to help.

此外，您正在使用 mapped =>false 我不确定这是你想要的，因为它阻止 Symfony 用表单数据更新实体.

Also, you're using mapped => false which I'm not sure is what you want because it prevent Symfony from updating entities with form data.
