Hallo @JohnEstropia
I'am trying this library that seems great, i want to ask about how add / update unique object

for example i have 2 object FlightBookingInfo has one FlightBookingDetail, i want to update FlightBookingInfo and also FlightBookingDetail from my json that i got from the API, i can add or update FlightBookingInfo but FlightBookingDetail value is inserted instead of update existing value that has relationship to FlightBookingInfo

May i know how to update FlightBookingDetail from json, without fetching it first from database?

FlightBookingInfo

class FlightBookingInfo: CoreStoreObject, ImportableUniqueObject {
    
    typealias UniqueIDType = String
    
    static var uniqueIDKeyPath: String = String(keyPath: \FlightBookingInfo.$invoiceId)
    
    typealias ImportSource = [String: Any]
    
    @Field.Stored("invoiceId")
    var invoiceId: String = ""
    
    @Field.Stored("bookingStatus")
    var bookingStatus: String = ""
    
    @Field.Stored("rescheduleId")
    var rescheduleId: String = ""
    
    @Field.Relationship("flightBookingDetail", inverse: \.$flightBookingInfo, deleteRule: .cascade)
    var flightBookingDetail: FlightBookingDetail?
    
    static func uniqueID(from source: [String : Any], in transaction: CoreStore.BaseDataTransaction) throws -> String? {
        return source["invoiceId"] as? String
    }
    
    func update(from source: [String : Any], in transaction: CoreStore.BaseDataTransaction) throws {
        self.invoiceId = source["invoiceId"] as? String ?? ""
        self.bookingStatus = source["bookingStatus"] as? String ?? ""
        self.rescheduleId = source["rescheduleId"] as? String ?? ""
        self.flightBookingDetail = try transaction.importObject(Into<FlightBookingDetail>(), source: source)
    }
}

FlightBookingDetail

class FlightBookingDetail: CoreStoreObject, ImportableUniqueObject {
    
    static func uniqueID(from source: [String : Any], in transaction: CoreStore.BaseDataTransaction) throws -> String? {
        return source["invoiceId"] as? String
    }
    
    typealias UniqueIDType = String
    
    static var uniqueIDKeyPath: String = String(keyPath: \FlightBookingInfo.$invoiceId)
    
    func update(from source: [String : Any], in transaction: CoreStore.BaseDataTransaction) throws {
        let flightBookingDetailSource = source["flightBookingDetail"] as? [String: Any] ?? [:]
        multipleAirlines = flightBookingDetailSource["multipleAirlines"] as? Bool ?? false
        twoWay = flightBookingDetailSource["twoWay"] as? Bool ?? false
        originDate = flightBookingDetailSource["originDate"] as? Date
        returnFlightDate = flightBookingDetailSource["returnFlightDate"] as? Date
    }
    
    
    typealias ImportSource = [String: Any]
    
    @Field.Stored("multipleAirlines")
    var multipleAirlines: Bool = false
    
    @Field.Stored("twoWay")
    var twoWay: Bool = false
    
    @Field.Stored("originDate")
    var originDate: Date?
    
    @Field.Stored("returnFlightDate")
    var returnFlightDate: Date?
    
    @Field.Relationship("flightBookingInfo")
    var flightBookingInfo: FlightBookingInfo?
}

Here is how i add/update the data

      let jsonData: [String: Any] = [
            "invoiceId": "1111",
            "bookingStatus": "\(["failed", "success", "pending"].randomElement()!)",
            "rescheduleId": "\(Int.random(in: 1000..<2000))",
            "flightBookingDetail": [
                "multipleAirlines": Bool.random(),
                "twoWay": Bool.random(),
                "originDate": Date.now,
                "returnFlightDate":  Calendar.current.date(byAdding: .day, value: 1, to: Date.now),
            ]
        ]
        
        CoreDataManager.instance.dataStack?.perform(
            asynchronous: { transaction in
                try transaction.importUniqueObject(Into<FlightBookingInfo>(), source: jsonData)
            }, success: { _ in
                print("add / update FlightBookingInfo success")
            }, failure: { _ in
                print("add / update FlightBookingInfo failed")
            }
        )
