How can save a relation object from a custom class ?

[khoo]

Here my code but it does not save the relation of status class

 let activity = Activity()
 activity.fromUser = backendless.userService.currentUser
 activity.toUser = userId as! BackendlessUser
 activity.type = "likes"
 activity.status?.objectId = self.loadLikes[sender.tag].3 //An object Id
 
 
 let activityStore = backendless.data.of(Activity.ofClass())
 
 activityStore.save(
 activity,
 response: { (result: AnyObject!) -> Void in
 print("Follow Have Been Successfully Uploaded(Activity Class) --- StatusUpload (UIViewController)")
 
 },
 error: { (fault: Fault!) -> Void in
 print("fServer reported an error: \(fault)")
 
 }) // save object asynchronously
