Closed last month.

I need help how can I use user model. when creating the account instead of generating the parent node with email. make the main node the uid. I tried some modifications but I was not successful someone could help me. the account is created by google auth wanted that instead of email it would generate a main uid node.

---

I searched for models but I was not successful if someone can help me I would be very grateful

---

I still need the email but not as a main node. for the main node I wanted the uid that is already in the model, but I'm not able to make this change :(

Answer 1

Solution

changed from

FirebaseUtils.getUserRef(account.getEmail())
                                    .setValue(user,

to

 FirebaseDatabase.getInstance().getReference("users")
                                        .child(FirebaseAuth.getInstance().getCurrentUser().getUid())
                                        .setValue(user)

Answer 2

                       val ref = database.push().key

                        database.child(ref).setValue(mapinfoinstance)

'mapinfoinstance' is an instance of my class.
