我想根据Twig中表单中的测试ID编辑我的类别实体并将其绑定到数据库， 当我打开编辑时，它会显示我编辑的表单，但它们没有绑定数据库中的 id 测试，我不明白为什么，可能是我写错了:( 我的控制器：
class DefaultController extends Controller
{
function editAction($id)
{
$em = $this->getDoctrine()->getEntityManager();
$test = $em->getRepository('LadelaOdeskTesterBundle:Test')->find($id);
if (!$test) {
throw $this->createNotFoundException('Unable to find Advertiser entity.');
}
return array(
'test' => $test,
);
}
/**
* @Route("/new/{id}/update", name="test.update", requirements={"id" = "\d+"})
* @Method("Post")
* @Template("LadelaOdeskTesterBundle:Default:edit.html.twig")
*/
公共函数 updateAction($id) {
$test =
$this->getDoctrine()->getRepository('LadelaOdeskTesterBundle:Test')->find($id);
if (!$test) {
throw $this->createNotFoundException('Unable to find Test entity.');
}
$success = 0;
$categoryList = array_map('trim', $this->getRequest()->get('category-new'));
$currentCats = $test->getCategories();
foreach ($currentCats as $current){
$test->removeCategorie($current);
}
$em = $this->getDoctrine()->getEntityManager();
foreach ($categoryList as $category) {
if (!empty($category)) {
$categoryName = new Category();
$categoryName->setName($category);
$categoryName->setTest($test);
$test->addCategorie($categoryName);
$em->persist($categoryName);
$success = ' Category ' . $category . ' was created';
}
}
$em->flush();
return $this->redirect($this->generateUrl('test.edit',array('id' => $id)));
return array(
'test' => $test,
);
}
}

在 foreach 循环中 > 如果您从未将 $test 添加到类别对象。 添加这个：
$categoryName->setTest($test);
foreach 循环应该如下所示：
$em = $this->getDoctrine()->getManager(); // <---- Changed this
foreach ($categoryList as $category) {
if (!empty($category)) {
$categoryName = new Category();
$categoryName->setName($category);
$categoryName->setTest($test);
$em->persist($categoryName);
$success = ' Category ' . $category . ' was created';
} else {
$success = 'Test category-new may not be empty';
}
}
$em->flush(); // <---- Changed this
在 foreach 循环之前添加：
$currentCats = $test->getCategories();
foreach ($currentCats as $current){
$test->removeCategorie($current);
}
最终编辑：
不要为类别设置测试，而是添加要测试的类别，如下所示：
$em = $this->getDoctrine()->getManager();
foreach ($categoryList as $category) {
if (!empty($category)) {
$categoryName = new Category();
$categoryName->setName($category);
$categoryName->setTest($test);
$test->addCategorie($categoryName); // <---- This is added
$em->persist($categoryName);
$success = ' Category ' . $category . ' was created';
} else {
$success = 'Test category-new may not be empty';
}
}
$em->flush();
