我使用类Appointment
创建了一个extbase扩展,其中包含属性expertises
和另一个相同类型的subExpertises
。
这就是它们在Appointment
类中的样子(subExpertises
是相同的):
/**
* expertises
*
* @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<...\Domain\Model\Expertise>
*/
protected $expertises = NULL;
/**
* Adds an expertise
*
* @param ...\Domain\Model\Expertise $expertise
* @return void
*/
public function addExpertise(...\Domain\Model\Expertise $expertise) {
$this->expertises->attach($expertise);
}
在以流畅的形式编辑约会后,在控制器中执行此代码时出现错误:
/**
*
* @param \Domain\Model\Appointment $appointment
* @return void
*/
public function bookAction(\Domain\Model\Appointment $appointment) {
//empty all expertises of appointment - then fill them with the selected from lawyer
$appointment->setExpertises(new \TYPO3\CMS\Extbase\Persistence\ObjectStorage());
$appointment->setSubExpertises(new \TYPO3\CMS\Extbase\Persistence\ObjectStorage());
//add all checked expertises of lawyer to appointment
foreach ($appointment->getLawyer()->getExpertises() as $expertise) {
if ($expertise->getChecked()) {
$appointment->addExpertise($expertise);
}
foreach ($expertise->getSubExpertises() as $subExpertise) {
if ($subExpertise->getChecked()) {
$appointment->addSubExpertise($subExpertise);
}
}
}
$this->appointmentRepository->update($appointment);
}
这是错误:
致命错误:在/var/www/typo3_src/typo3_src-6.2.25/typo3/sysext/extbase/Classes/Persistence/Generic/Backend.php中调用未定义的方法\ Domain \ Model \ Expertise :: getPosition()在第453行
现在似乎TYPO3认为Expertise
属于ObjectStorage
类型,因为它试图调用getPosition()
,但我不知道为什么它会这样做而且< strong>我应该更改,以便使用新Appointment
成功保存我的Expertises
对象。
我尝试调试约会对象,但我找不到问题 - 对我来说似乎没关系,只是表明expertises
和subExpertises
已被修改。

Extbase中的Getter方法并不神奇,你必须明确定义它们。
如果您正在处理n:n-relation,则还需要在模型中将Property初始化为ObjectStorage并在TCA中对其进行配置。
/**
* Initialize all ObjectStorage properties.
*
* @return void
*/
protected function initStorageObjects() {
$this->yourProperty = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
}
