所以我使用的是Symfony 2，有时在调用updateAction时，我从symfony中获得了以下500错误：
“执行'INSERT INTO topic_sources时发生异常 （平台，作者，关键字，rss_feeds，topic_id）VALUES（？，？，？，？， ？）'与params [“facebook”，“153213781413350”，null， “https://www.facebook.com/HuffPostWomen”，4641]：SQLSTATE [23000]： 违反完整性约束：1062重复条目'4641-facebook' 关键'PRIMARY'“......等等
我理解这个问题与它试图插入已存在的行有关，但我不明白为什么会发生这种情况......我的印象是symfony和Doctrine管理这个。这是我的updateAction的代码：
public function updateAction($id) {
$topic = $this->getTopic($id);
if (!$topic) {
throw $this->createNotFoundException('No topic found for id ' . $id);
}
$originalTopicSources = new ArrayCollection();
// Grab all the topic sources on the page
foreach ($topic->getTopicSources() as $topicSource) {
$originalTopicSources->add($topicSource);
}
// Get all the Request Data
$request = $this->getRequest();
$requestData = $request->request->all();
$imageData = $request->get("topic-image");
$em = $this->getDoctrine()
->getManager();
// Bind the form for validation
$editTopicForm = $this->createForm(new TopicType($em), $topic);
$editTopicForm->bind($request);
if ($editTopicForm->isValid()) {
// Grab image and decode
if ($imageData) {
list($type, $imageData) = explode(';', $imageData);
list(, $imageData) = explode(',', $imageData);
$data = base64_decode($imageData);
$filename = "$id." . explode("/", $type)[1];
$topic->setImage($filename);
file_put_contents($this->get('kernel')->getRootDir() . "/../web/uploads/topics/$filename", $data);
}
set_time_limit(10);
// Compare the original topic sources with the newly passed in form and remove any topic sources that aren't common between the two
foreach ($originalTopicSources as $topicSource) {
if (false === $topic->getTopicSources()->contains($topicSource)) {
$em->remove($topicSource);
}
}
$em->persist($topic);
$em->flush();
$this->addFlash('success','The topic has been updated successfully :)');
}
$project = $topic->getProject();
$projectForm = $this->createForm(new ProjectType(array("user" => $this->getUser())), $project);
$newTopic = new Topic();
$newTopicForm = $this->createForm(new NewTopicType(), $newTopic);
// Get tag names
$em = $this->getDoctrine()
->getEntityManager();
$response = array();
$tags = $em->getRepository('AppBundle:Tag')->findAll();
$tagNames = array();
foreach ($tags as $tag) {
array_push($tagNames, $tag->getName());
}
return $this->render('AppBundle:Topic:edit.html.twig', array(
'project' => $topic->getProject(),
'projectForm' => $projectForm->createView(),
'newTopicForm' => $newTopicForm->createView(),
'tags' => $tagNames,
'topic' => $topic,
'editTopicForm' => $editTopicForm->createView(),
'facebook_app_id' => $this->container->getParameter('facebook_app_id_'.$this->get('kernel')->getEnvironment()),
'facebook_app_secret' => $this->container->getParameter('facebook_app_secret_'.$this->get('kernel')->getEnvironment()),
'facebook_app_access_token' => $this->container->getParameter('facebook_app_access_token_'.$this->get('kernel')->getEnvironment())
));
}
非常感谢任何帮助......我在这里失去理智！
