无法确定 class "App\Form\OrderType" 中属性 "offerOrders" 的访问类型：属性都不是

Question

错误是：

Could not determine access type for property "offerOrders" in class "App\Form\OrderType": Neither the property "offerOrders" nor one of the methods "addOfferOrder()"/"removeOfferOrder()", "setOfferOrders()", "offerOrders()", "__set()" or "__call()" exist and have public access in class "App\Form\OrderType"..

对于冗长的代码块，我深表歉意，但对于那些将尝试解决该错误的人，我认为这是必要的。当我提交表单时返回错误。我问自己的问题是为什么 symfony 在 App\Form\OrderType class?

中寻找访问器

我在 PropertyAccessor.php PropertyPathMapper.php 和 vendor/symfony/form/Form.php 中到处都放了转储，当它出现在这里时：

if (FormUtil::isEmpty($viewData)) {
    $emptyData = $this->config->getEmptyData();

    if ($emptyData instanceof \Closure) {
        $emptyData = $emptyData($this, $viewData);
    }

    $viewData = $emptyData;
    dump($viewData);
 }

在 Form.php 中它将 $viewData 设置为 App\Form\OrderType 但我不知道为什么

答案是：

为了通过表单，必须像这样更改 photoSessionType 中的 purchaseOrder：

-> add ('purchaseOrder', OrderType :: class)

再次感谢@Ihor Kostrov

Answer 1

尝试改变

->add('purchaseOrder', OrderType::class, [
                'data_class' => OrderType::class
            ])

到

->add('purchaseOrder', OrderType::class, [
                'data_class' => Order::class
            ])

或者只删除 data_class 选项
