Question

我有这个Facade实体，每次尝试修改包含下面的树枝的表单时，它都会返回此错误：

json

我的控制器操作：

mysql

我的树枝模板

An exception has been thrown during the rendering of a template ("Parameter "buildings_id" for route "addFacade" must match "[^/]++" ("" given) to generate a corresponding URL.").

我试图转储我的/** * @Route("/{id}/card", name="business_card", methods="GET|POST|DELETE", defaults={"business_id"=1}) * @param Request $request * @param Business $business * @return Response */ public function show_card(Request $request, Business $business): Response { $businessCard = $business->getBusinessCard(); $formCard = $this->createForm(BusinessCardType::class, $businessCard); $formCard->handleRequest($request); if (($formCard->isSubmitted() && $formCard->isValid())) { $businessCard = $formCard->getData(); $em = $this->getDoctrine()->getManager(); $em->persist($businessCard); $em->flush(); return $this->redirectToRoute('business_card', ['id' => $business->getId()]); } $dict = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J'); return $this->render('business/card.html.twig', ['business' => $business, 'formCard' => $formCard->createView(), 'dict' => $dict]); }变量，但是数组的所有值都是数字（没有空值）。我还尝试在控制器中为参数{% for buildingsInfo in business.businessCard.buildingsInfos %} {% set idBuildingsInfo = idBuildingsInfo|merge([buildingsInfo.id]) %} <a class="btn btn-outline-primary mb-3" href="{{ path("addFacade",{"buildings_id": idBuildingsInfo[j] }) }}">Ajouter une façade</a> {% endfor %}添加一个默认值，但是它似乎没有任何改变。

仔细阅读错误

参数“ buildings_id” ...（已给出“”）

您传递的参数值为空（“”）

Before:

 (1.000000, 0.000000)  (0.500000, 0.000000)  (0.333333, 0.000000)
 (0.250000, 0.000000)  (0.200000, 0.000000)  (0.166667, 0.000000)
 (0.142857, 0.000000)  (0.125000, 0.000000)  (0.111111, 0.000000)
 (0.100000, 0.000000)  (0.090909, 0.000000)  (0.083333, 0.000000)

After:

 (1.000000, 0.000000)  (0.500000, 0.000000)  (0.333333, 0.000000)
 (0.175000, 0.000000)  (0.200000, 0.000000)  (0.125000, 0.000000)
 (0.142857, 0.000000)  (0.125000, -0.000000)  (0.111111, 0.000000)
 (0.175000, 0.000000)  (0.090909, 0.000000)  (0.125000, 0.000000)

是否定义了{{ path("addFacade",{"buildings_id": idBuildingsInfo[j] }) }}？还是该行应如下所示：

Answer 2

我的猜测是该错误可能与以下情况有关：

href="{{ path("addFacade",{"buildings_id": idBuildingsInfo[j] }) }}

也许我们会set为href设置一个变量，然后转义那些需要转义的"，我们的代码将如下所示：

{% for buildingsInfo in business.businessCard.buildingsInfos %}
{% set idBuildingsInfo = idBuildingsInfo|merge([buildingsInfo.id]) %}
{% set path = "\"addFacade\", {\"buildings_id\": idBuildingsInfo[j]" %}
<a class="btn btn-outline-primary mb-3" href="{{ path }}">Ajouter une façade</a>
{% endfor %}

或类似。

路径“”的参数“”必须与“ [^ /] ++”（给定的“”）匹配，以生成相应的URL
