Symfony 4 单一形式的多个实体
Symfony 4 multiple entities in single form
我花了好几个小时尝试让我的多实体表单正常工作，但它真的让我头疼，none 我找到的例子很有效。
我检查了Collection form type documentation and form collections, as well as the Entity form type。
我有一个 User 实体、UserRole 实体和一个 Role 实体。
UserRole 包含一个 userID 和一个 roleID。只是一个链接 table.
表单显示了用于创建用户的字段，我也希望能够 select 为新用户创建一个新角色。所以我尝试使用 EntityType，一个 select 下拉列表很好地显示了所有角色（仅当我添加选项 mapped => false 时），但在表单提交后不处理。
它的数据不在 $form->getData() 中，用户被创建，user_role 条目从未创建。
如果我在没有 mapped => false 的情况下尝试它，它会抛出我：
Could not determine access type for property "user_roles" in class "App\Entity\User": The property "user_roles" in class "App\Entity\User" can be defined with the methods "addUserRole()", "removeUserRole()" but the new value must be an array or an instance of \Traversable, "App\Entity\Role" given..
代码：
$form = $this->createFormBuilder(new User)
... //other add entries
->add('user_roles', EntityType::class, array(
'label' => 'Group (role)',
'class' => Role::class,
'choice_label' => 'name',
// 'mapped' => false, // Form works when false, but doesn't save/create UserRole entry
))
->getForm();
$form->handleRequest($request);
使用 CollectionType 它根本不显示 select 下拉列表。
代码：
$form = $this->createFormBuilder($user)
.... //other add entries
->add('user_roles', CollectionType::class, array(
'entry_type' => ChoiceType::class,
'entry_options' => array(
'choices' => $roleChoices,
),
))
->getForm();
$form->handleRequest($request);
我是不是在我的控制器代码中遗漏了什么，或者我是否误解了表单类型的使用？我真的不知道我做错了什么。

在 Symfony 中，要获取未映射的表单数据，请尝试这样做。
$data = $form->getData();
$roles = $form->get("user_roles")->getData();
另外，注意到一件事。在下面的代码块中，class 不应该是 UserRole::class 而不是 Role::class。
$form = $this->createFormBuilder(new User)
... //other add entries
->add('user_roles', EntityType::class, array(
'label' => 'Group (role)',
'class' => Role::class,
'choice_label' => 'name',
// 'mapped' => false, // Form works when false, but doesn't save/create UserRole entry
))
->getForm();
希望这对您有所帮助，
干杯..
你选择的大致方式是可以的。坚持使用 EntityType 并删除 mapped = false，这将告诉 Symfony 忽略该字段。
我想问题是：您的 class 中混合了 $this->user_role 和 $this->user_role，可能是重命名的变量。首先在 __construct()、addUserRole()、removeUserRole()、getUserRoles()、getUserRole() 中清理它。
然后添加一个方法
public function setUserRoles($userRoles)
{
$this->user_roles = new ArrayCollection();
foreach ($userRoles as $role) {
$this->addUserRole($role);
}
return $this;
}
我花了好几个小时尝试让我的多实体表单正常工作，但它真的让我头疼，none 我找到的例子很有效。
我检查了Collection form type documentation and form collections, as well as the Entity form type。
我有一个 User 实体、UserRole 实体和一个 Role 实体。 UserRole 包含一个 userID 和一个 roleID。只是一个链接 table.
表单显示了用于创建用户的字段，我也希望能够 select 为新用户创建一个新角色。所以我尝试使用 EntityType，一个 select 下拉列表很好地显示了所有角色（仅当我添加选项 mapped => false 时），但在表单提交后不处理。 它的数据不在 $form->getData() 中，用户被创建，user_role 条目从未创建。 如果我在没有 mapped => false 的情况下尝试它，它会抛出我：
Could not determine access type for property "user_roles" in class "App\Entity\User": The property "user_roles" in class "App\Entity\User" can be defined with the methods "addUserRole()", "removeUserRole()" but the new value must be an array or an instance of \Traversable, "App\Entity\Role" given..
代码：
$form = $this->createFormBuilder(new User)
... //other add entries
->add('user_roles', EntityType::class, array(
'label' => 'Group (role)',
'class' => Role::class,
'choice_label' => 'name',
// 'mapped' => false, // Form works when false, but doesn't save/create UserRole entry
))
->getForm();
$form->handleRequest($request);
使用 CollectionType 它根本不显示 select 下拉列表。 代码：
$form = $this->createFormBuilder($user)
.... //other add entries
->add('user_roles', CollectionType::class, array(
'entry_type' => ChoiceType::class,
'entry_options' => array(
'choices' => $roleChoices,
),
))
->getForm();
$form->handleRequest($request);
我是不是在我的控制器代码中遗漏了什么，或者我是否误解了表单类型的使用？我真的不知道我做错了什么。

在 Symfony 中，要获取未映射的表单数据，请尝试这样做。
$data = $form->getData();
$roles = $form->get("user_roles")->getData();
另外，注意到一件事。在下面的代码块中，class 不应该是 UserRole::class 而不是 Role::class。
$form = $this->createFormBuilder(new User)
... //other add entries
->add('user_roles', EntityType::class, array(
'label' => 'Group (role)',
'class' => Role::class,
'choice_label' => 'name',
// 'mapped' => false, // Form works when false, but doesn't save/create UserRole entry
))
->getForm();
希望这对您有所帮助， 干杯..
你选择的大致方式是可以的。坚持使用 EntityType 并删除 mapped = false，这将告诉 Symfony 忽略该字段。
我想问题是：您的 class 中混合了 $this->user_role 和 $this->user_role，可能是重命名的变量。首先在 __construct()、addUserRole()、removeUserRole()、getUserRoles()、getUserRole() 中清理它。
然后添加一个方法
public function setUserRoles($userRoles)
{
$this->user_roles = new ArrayCollection();
foreach ($userRoles as $role) {
$this->addUserRole($role);
}
return $this;
}
