您好，我的多个嵌入表单（一对多）有问题。一场比赛有多种奖品，一种奖品有多种选择。当我尝试保存此表单时收到错误消息
SQLSTATE [23000]：违反完整性约束：1048 列“fk_prize”不能为空
我已经在我的实体中设置了级联并且在我的表单类型中设置了 by_refference false 但没有工作。所有其他分配的外键都可以正常工作。
更新： 在控制器中，当我成功保存此表单时。但我想用教义来做到这一点。是教义错误还是我的代码有问题？谢谢你的时间！
//Hacked code in controller to save the form
$prizes = $data->getPrizes();
foreach ($prizes as $prize) {
$prizeOptions = $prize->getPrizesOptions();
foreach ($prizeOptions as $prizeOption) {
$prizeOption->setPrize($prize);
}
}
$em->persist($data);
$em->flush();
