[英]Model with ManyToMany relationship not persisted with Doctrine in symfony when updated
我嘗試更新一個 model,但是當從 entityManager 調用 flush() 時,最后一個不會持久化。
代碼如下
/**
* @ORM\ManyToMany(targetEntity=GroupBase::class, inversedBy="baseUsers", cascade={"persist"})
*/
private $GroupBase;
// this is the variable used in the entity GroupBase
/**
* @ORM\ManyToMany(targetEntity=BaseUser::class, mappedBy="GroupBase", cascade={"persist"})
*/
private $baseUsers;
// this is the Entity GroupBase, which should contain a collection of User
public function addBaseUser(BaseUser $baseUser): self
{
if (!$this->baseUsers->contains($baseUser)) {
$this->baseUsers[] = $baseUser;
$baseUser->addGroupBase($this);
}
return $this;
}
// this methods is the one that insert Users in the GroupBase Collection
public function insertUsersGroup(LdapUser $ldapUser, GroupBase $groupBase){
/**
* this methods aim to insert all Users that belong to group Members into GroupBase
*/
$dn = $ldapUser->getDistinguishedName();
$members = $groupBase->getMembers();
if(in_array($dn, $members)){
$groupBase->addBaseUser($ldapUser);
$ldapUser->addGroupBase($groupBase);
}
return $groupBase;
}
這是在組中插入用戶的 controller
/**
* @Route("group/insertUsersGroup")
*/
public function insertUsersInGroup(){
$entityManager = $this->getDoctrine()->getManager();
$ldapUsers = $entityManager->getRepository(LdapUser::class)->findAll();
$groupBase = $entityManager->getRepository(GroupBase::class)->findAll();
foreach($groupBase as $group){
foreach($ldapUsers as $user){
$this->service->insertUsersGroup($user, $group);
try{
$entityManager->persist($group);
$entityManager->flush();
$response = "model saved";
}
catch(Exception $e){
throw $e;
}
}
}
return new Response(
$response
);
}
如果我在持久化數據之前調用方法 $groupBase->getBaseUsers() 它會告訴我我的用戶在這里,並且不會拋出任何錯誤。 但似乎數據在$entitymanager->flush()之后沒有持久化
查看您提供的要點 -https://gist.github.com/lobamo/209d67b71fad18dc61e20d7a411e2780
我看到 Entity/User.php 具有以下內容:
abstract class BaseUser
{
這是故意的嗎? 我認為實體不應該是抽象的 class。
根據 PHP 的定義,在https://www.php.net/manual/en/language.oop5.abstract.php
定義為抽象的類不能被實例化,任何包含至少一個抽象方法的 class 也必須是抽象的。
