scala提交和回滚事务

Question

如果其中一个失败，我需要回滚查询

我已尝试过此功能，但它不带参数

added = models.DateTimeField(auto_now_add=True, null=True, blank=True,)
last_updated = models.DateTimeField(auto_now=True, null=True, blank=True,)

这是我需要 val trans = ( for { insertPerson <- PersonDal.insert deletePerson <- PersonDal.delete } yield ()).transactionally def futureTest = db.run(trans) 参数

的服务

case class

如何在提交和回滚的查询中使用 def updateEntryInsuranceRate(insurancerate: EntryInsuranceRate): Future[Int] = { db.run(DalEntryInsuranceRate.updateEntryInsuranceRate(insurancerate)) } def deleteEntryInsuranceRate(insurancerate: EntryInsuranceRate): Future[Int] = { db.run(DalEntryInsuranceRate.deleteEntryInsuranceRate(insurancerate)) } 或其他transactionally？
