我无法在表单中呈现我的嵌套集合。当加载空表单时，paintOffers 中的 paintOffers 集合和 translations 集合都显示正确，但是因为我无法让嵌套的 translations 集合显示在 { {1}} 添加第二个“油漆报价”时不显示翻译。
更新：
我发现 data-prototype 的宏无法循环翻译，因为它们没有提供给原型：
data-prototype虽然它应该与paintOffers表单中的相同：
"prototype" => FormView {#2813 ▼
+vars: array:24 [▶]
+parent: FormView {#2805}
+children: array:7 [▼
...
"translations" => FormView {#3130 ▼
+vars: array:30 [ …30]
+parent: FormView {#2813}
+children: [] # NO LANGUAGE PROVIDED
...
语言环境是通过 OfferedByDTO 构造函数提供的：
+children: array:7 [▼
...
"translations" => FormView {#3350 ▼
+vars: array:30 [▶]
+parent: FormView {#3330}
+children: array:1 [▼ # LANGUAGE IS PROVIDED
"en" => FormView {#3357 ▼
+vars: array:24 [ …24]
+parent: FormView {#3350}
+children: array:1 [ …1]
-rendered: false
-methodRendered: false
我不知道我应该更改什么以确保 public function __construct(OfferedBy $offeredBy = null)
{
$this->offeredByEntity = $offeredBy;
$this->translations = new ArrayCollection();
if (!$this->hasExistingOffer()) {
foreach (array_keys(Language::getWorkingLanguages()) as $workingLanguage) {
$this->translations->set(
$workingLanguage,
new OfferedByTranslationDataTransferObject(
null,
Locale::fromString($workingLanguage)
)
);
}
return;
}
...
集合中的数据也提供给 translations？
