Subcollection in Firestore

Question

I can't create a document in a non existing subcollection.

I have a collection users, with a document that has the userId as Id. In this document I want a subcollection orders

the orders subcollection is not created yet. But you cant create empty subcollections.

So I do this:

const OrderID = 1; //just for testing
const ref = doc(
        db,
        "users",
        getAuth().currentUser.uid,
        "orders",
        OrderID
      );

But that does not work.

How can I do this?

Answer 1

Ok found it OrderID can't be a number. It must be a string. The error I got did not tell me that. It complained about an out of range function.....

const OrderID = 1; //just for testing
const ref = doc(
        db,
        "users",
        getAuth().currentUser.uid,
        "orders",
        OrderID.toString()
      );
