Updating referencecollection overrides data

[madsodgaard]

Hello.

I am currently trying to insert a new item into a ReferenceCollection of a User object (followers ex)

As the item I am inserting already exists, right now when I try to update() on the user object I am inserting to, it overrides the data for the referenced object. I am only initating the object with an ID for the document, so it sets all the fields to null.

If the update methods also updates the references, wouldn't that be inconvienient if the other object is updated in between, would mean the data would be rolled back?

if let userSnapshot = snapshot.documents.first
                                {
                                    user.friends.insert(CHUser(id: id))
                                    user.update({ (error) in
                                        if let error = error
                                        {
                                            print(error)
                                            completion(CHError.UnknownError, nil)
                                            return
                                        }
                                        
                                        completion(nil, userSnapshot.documentID)
                                    })
                                }

Hi.
I recommend you to create social features.

It is the engineer's responsibility to decide whether it has already been saved.
Object already stored in Pring Initialize as follows.

let user: User = User(id: "USER_ID") // is not saved
let user: User = User(id: "USER_ID", value: [:]) // is saved
