为什么自定义验证中的错误会限制未附加到表单的特定字段? [英] Why errors from custom validation constrain not attached to specific field by to the form?

问题描述

我有一个 ArticelPattern 类，它具有 $extraPatterns 属性.此属性是一个 ExtraPattern(类)元素数组.

I have an ArticelPattern class which has $extraPatterns property. This property is an array of ExtraPattern (class) elements.

ExtraPattern 类有一个自定义约束(我使用注释应用).

There is a custom constraint on the class ExtraPattern (which I apply using annotation).

为了处理表单，我创建了一个带有 extraPatterns 集合字段的 ArticelPatternType 类.

For form handling I created an ArticelPatternType class with extraPatterns collection field.

现在，当我验证此表单并且 ArticelPattern::$extraPatterns 集合的元素之一引发约束违规时，错误未分配给该元素，而是分配给整个表单，因此我无法在导致此错误的相应表单字段旁边显示此错误.

Now, when I validate this form and there is a constraint violation raised by one of the elements of the ArticelPattern::$extraPatterns collection, the error isn't assigned to that element, but instead to the whole form, so I can't display this error beside the appropriate form field which caused this error.

而不是将我的自定义约束放在 ExtraPattern 类上，如下所示:

Instead of putting my custom constraint on the ExtraPattern class, like this:

/**
 * @AssertApl
 */
class ExtraPattern 

我也试过把它放在集合属性上，像这样:

I also tried putting it on the collection property, like this:

/**
 * @Assert\All(@AssertApl)
 */
private $extraPatterns;

但结果相同.由这个集合的元素引起的@AssertApl 约束错误不是分配给它们，而是分配给整个表单.

But with the same result. @AssertApl constraint errors caused by elements of this collection are not assigned to them, but to the whole form.

知道如何让它工作吗?

推荐答案

你的类约束可能被映射到一个 form 类型的表单，它有 error_bubbling 启用默认.将此选项设置为 false 应该可以满足您的要求.

You class constraint is probably being mapped to a form of form type, which has error_bubbling enabled by default. Setting this option to false should do what you're looking for.

$builder ->add('extraPatterns', 'collection', array(
    // ...
    'options' => array('error_bubbling' => false),
));
