如何在Firebase中的现有节点上插入新值？

Question

I am quite confused about how to insert a new value into an existing node in firebase?

like the pic below, when I try to upload the Route object, I also wanna the uploadedRoute can the Route object's key in. I have tried with setValue, but it will delete the old value, what I want is something like "append" the key, but I really have no idea, could someone give me a hint?

Answer 1

Is this the kind of structure you would like to get ?

If so, you may try this :

dataRef.child("data/users/\(userID)/Routes/uploadedRoutes/\(routeID)").updateChildValues(["isUploaded": true])
