getViewData 与 getNormData 和 DataTransformers - 根据上下文不同的结果

问题描述

我有一个包含多个字段的表单.

I have a form with several fields.

然后我将 DataTransformer 绑定到其中之一.如果我获取数据 getViewData 和 getNormData，Transformer 可以正常工作.

Then I bound DataTransformer to the one of them. Transformer works correctly if I get data getViewData and getNormData.

但是如果我在整个表单上发出这些方法，转换器处理的数据将被完全忽略.

But if I issue these methods on whole form, data processed by transformers are completely ignored.

Form 中的数据由于以下原因被覆盖:

In Form data is being overwritten due to the:

$childrenIterator = new InheritDataAwareIterator($this->children);
$childrenIterator = new \RecursiveIteratorIterator($childrenIterator);
$this->config->getDataMapper()->mapFormsToData($childrenIterator, $viewData);

我的映射器是 PropertyPathMapper.不幸的是，它基于每个孩子的 getData 方法.

My mapper is PropertyPathMapper. Unfortunately, it bases on getData method of each child.

是否有可能绕过 viewData 覆盖/实现正确转换的数据而无需编写全局转换器?

Is it possible to bypass viewData overwrite / achieve correctly transformed data without writing a global transformer?

推荐答案

解决方法:

$data = array();
foreach ($form->all() as $k => $el) {
    $data[$k] = $el->getData(); // or getNormData or getViewData
}

很遗憾我没有解决方案.

Unfortunately I have no solution.

当前的行为不是我所期望的.至少应该在 在 symfony 食谱 中提及.

The current behaviour is not what I expected. It should at least be mentioned in the symfony cookbook.

如您所见，我遇到了同样的问题.我写了一个测试用例，以确保我不会误解变压器的工作原理.我后来发现了你的问题.

As you see I have the same problem. I wrote a test case to be sure that I do not misunderstand how the transformers work. I found your question later.
