Symfony 形式的多对多数组集合
我正在开发一个 Symfony 项目，其中有两种类型的 User Client 和 EmployeSpie，两者都有自己的实体。
当您创建/编辑用户时，您可以将 EmployeSpie 链接到客户端。这就是我的问题所在，当我编辑或创建用户时，我可以创建一个用户，但我的表中没有存储任何内容来建立我的表 Client 和 EmployeSpie 之间的链接。
这是我所做的：
我的实体客户有这样的：
class Client extends User
{
/**
* @ORM\ManyToMany(targetEntity=EmployeSpie::class, mappedBy="clients", cascade={"persist"})
*/
private $employeSpies;
/**
* @return Collection|EmployeSpie[]
*/
public function getEmployeSpies(): Collection
{
return $this->employeSpies;
}
public function addEmployeSpy(EmployeSpie $employeSpy): self
{
if (!$this->employeSpies->contains($employeSpy)) {
$this->employeSpies[] = $employeSpy;
$employeSpy->addClientEmploye($this);
}
return $this;
}
public function removeEmployeSpy(EmployeSpie $employeSpy): self
{
if ($this->employeSpies->contains($employeSpy)) {
$this->employeSpies->removeElement($employeSpy);
$employeSpy->removeClientEmploye($this);
}
return $this;
}
}
和我的表 EmployeSpie：
class EmployeSpie extends User
{
/**
* @ORM\ManyToMany(targetEntity=Client::class, inversedBy="employeSpies")
*/
private $clients;
/**
* @return Collection|Client[]
*/
public function getClients(): Collection
{
return $this->clients;
}
public function addClient(Client $client): self
{
if (!$this->clients->contains($client)) {
$this->clients[] = $client;
}
return $this;
}
public function removeClient(Client $client): self
{
if ($this->clients->contains($client)) {
$this->clients->removeElement($client);
}
return $this;
}
public function __toString()
{
return $this->getPrenom()." ".$this->getNom();
}

还需要一些其他的改变。在我的客户实体中，我必须更改： public function addEmployeSpy(EmployeSpie $employeSpy): self { if (!$this->employeSpies->contains($employeSpy)) { $this->employeSpies[] = $employeSpy; $employeSpy->addClientEmploye($this); } return $this; }到 ： public function addEmployeSpy(EmployeSpie $employeSpy): self { if (!$this->employeSpies->contains($employeSpy)) { $this->employeSpies[] = $employeSpy; $employeSpy->addClient($this); } return $this; }删除也是同样的事情。public function removeEmployeSpy(EmployeSpie $employeSpy): self { if ($this->employeSpies->contains($employeSpy)) { $this->employeSpies->removeElement($employeSpy); $employeSpy->removeClientEmploye($this); } return $this; }到 ：public function removeEmployeSpy(EmployeSpie $employeSpy): self { if ($this->employeSpies->contains($employeSpy)) { $this->employeSpies->removeElement($employeSpy); $employeSpy->removeClient($this); } return $this; }但在我的 ClientType 进行其他更改之后： ->add('employeSpies', EntityType::class, array( 'class' => EmployeSpie::class , 'by_reference' => false, 'label' => 'Sélectionnez les employés rattachés à ce client', 'expanded' => false, 'multiple' => true, ))我需要添加'by_reference' => false,才能使其正常工作。因此，Symfony 不会尝试查找“setClient”方法，而是查找addClient方法希望它可以帮助以后其他人:)
