有人能指出我解决这个问题的正确方向吗？
Ps。我正在使用 symfony 5.0.7.
提前致谢
嗯，看我的代码答案并不明显，因为当你看到
$countries = $countryRepository->findByRegionId($region->getId());
您可能认为返回的是国家/地区数组，但实际上它只是 JS 的助手，只有 returns id 和 name
/**
* @param int $regionId
* @return array
*/
public function findByRegionId(int $regionId)
{
return $this->createQueryBuilder('c')
->select(['c.id', 'c.name'])
->where('c.region = :id')
->orderBy('c.name')
->setParameter('id', $regionId)
->getQuery()
->execute();
}
以防万一其他人遇到这个问题：$choices 需要一个对象数组，而不是一个带有 id 和名称的数组，所以我修改了我的 addCountryDropDown 方法，如下所示
private function addCountryDropdown(FormInterface $form, ?Region $region, ?Country $country)
{
$countries = array();
if ($region) {
$countryRepository = $this->em->getRepository(Country::class);
$countries = $countryRepository->findBy([
'region' => $region->getId()
]);
}
$form->add('country', EntityType::class, [
'required' => true,
'data' => $country,
'placeholder' => 'Select a Region first ...',
'class' => Country::class,
'choices' => $countries
]);
}
迁移到带有用户实体的 Symfony 5.4 后，我遇到了同样的错误。
现在 getRoles() 函数必须 return 角色列表作为字符串。
在我的例子中，我有一个实体角色。
我通过在用户实体中添加 getRolesObjects() 解决了这个问题：
public function getRolesObjects(): array
{
if(is_array($this->roles)) {
return $this->roles;
} else if($this->roles && ($this->roles instanceof Collection)) {
return $this->roles->toArray();
} else {
return [];
}
}
并在 FormType 中添加自定义 getter：
$builder
->add('firstName', TextType::class)
->add('lastName', TextType::class)
->add('email', TextType::class)
->add('roles', EntityType::class, [
'class' => Role::class,
'multiple' => true,
'getter' => function (User $user, FormInterface $form): array {
return $user->getRolesObjects();
}
]);

有人能指出我解决这个问题的正确方向吗？
Ps。我正在使用 symfony 5.0.7.
提前致谢
嗯，看我的代码答案并不明显，因为当你看到
$countries = $countryRepository->findByRegionId($region->getId());
您可能认为返回的是国家/地区数组，但实际上它只是 JS 的助手，只有 returns id 和 name
/**
* @param int $regionId
* @return array
*/
public function findByRegionId(int $regionId)
{
return $this->createQueryBuilder('c')
->select(['c.id', 'c.name'])
->where('c.region = :id')
->orderBy('c.name')
->setParameter('id', $regionId)
->getQuery()
->execute();
}
以防万一其他人遇到这个问题：$choices 需要一个对象数组，而不是一个带有 id 和名称的数组，所以我修改了我的 addCountryDropDown 方法，如下所示
private function addCountryDropdown(FormInterface $form, ?Region $region, ?Country $country)
{
$countries = array();
if ($region) {
$countryRepository = $this->em->getRepository(Country::class);
$countries = $countryRepository->findBy([
'region' => $region->getId()
]);
}
$form->add('country', EntityType::class, [
'required' => true,
'data' => $country,
'placeholder' => 'Select a Region first ...',
'class' => Country::class,
'choices' => $countries
]);
}
迁移到带有用户实体的 Symfony 5.4 后，我遇到了同样的错误。 现在 getRoles() 函数必须 return 角色列表作为字符串。 在我的例子中，我有一个实体角色。
我通过在用户实体中添加 getRolesObjects() 解决了这个问题：
public function getRolesObjects(): array
{
if(is_array($this->roles)) {
return $this->roles;
} else if($this->roles && ($this->roles instanceof Collection)) {
return $this->roles->toArray();
} else {
return [];
}
}
并在 FormType 中添加自定义 getter：
$builder
->add('firstName', TextType::class)
->add('lastName', TextType::class)
->add('email', TextType::class)
->add('roles', EntityType::class, [
'class' => Role::class,
'multiple' => true,
'getter' => function (User $user, FormInterface $form): array {
return $user->getRolesObjects();
}
]);
