如何更新云套件数据

Question

我有2种记录类型云套件数据库：

1. 人名单
2. 房间清单

占据了房间的人总是在变化。我有存储在引用的一个房间的人记录类型CKRecord.Reference。然而，这需要参考不断变化，因为人占据了房间不断变化。

我一直在挣扎，而无需创建一个新的记录更新基准。

我试图拉CKRecord出CkRecords的阵列为人民，创建一个新的参考房间，我想那个人占据并保存此参考回到个人记录，然后保存这个用CKModifyRecordsOperation对象。

然而，这似乎是建立在我的数据库一个新的记录，而不是更新当前之一。

if providerAssignedRoom == nil {
    self.roomAssignmentDelegate?.assignRoom(roomID: self.selectedRoomCKRecID, provider: provider, completion: self.transitionBackToRoot) 
}
else {
    let newProvider = self.searchCKRecArrayForProviderRef(providerRecID, self.providersCKRecsArray)
    let reference = CKRecord.Reference(recordID: 
    self.selectedRoomCKRecID, action: .none) 
    newProvider[RecordTypes.providerEnum.assignedRoom] = reference
    let operation = CKModifyRecordsOperation(recordsToSave: [record, newProvider], recordIDsToDelete: nil)
    operation.completionBlock = {
        print("record reference assigned to nil")
    }
    LaborFloorNamesDB.share.publicDatabase.add(operation)
}

Answer 1

该解决方案是简单地增加一个保存政策。我正在这复杂得多，它需要是。

let providerToBeAssigned = self.providersArray[indexPath.item]
let providerToBeAssignedCKRef = self.findProviderCKRecordBasedOnProviderObject(provider: providerToBeAssigned)

var roomToBeReferenced: CKRecord {
    let object = self.roomsAsCKRecsArray.filter {$0.recordID == self.selectedRoomCKRecID}
    let value = object.first
    return value!
}

if self.providerToBeRemoved != nil {
    self.providerToBeRemoved![RecordTypes.providerEnum.assignedRoom] = nil
}

providerToBeAssignedCKRef![RecordTypes.providerEnum.assignedRoom] = CKRecord.Reference(record: roomToBeReferenced, action: .none)

let operation = CKModifyRecordsOperation(recordsToSave: [providerToBeAssignedCKRef!, self.providerToBeRemoved!], recordIDsToDelete: nil)
operation.savePolicy = .changedKeys
operation.completionBlock = {
    print("record reference updated to cloud")
}

LaborFloorNamesDB.share.publicDatabase.add(operation)
