I'm using AngularFire2 for managing users and I want to find user by their id, remove them and create a new user.

public db: AngularFireDatabase
...
this.db.list('usernames', ref => ref.equalTo(uid)).remove();

This removes all users, rather than the one that has the same id.

The database looks like this - What am I doing wrong?

Maybe you should split it up. So first get the username you want to delete and then delete the username. – André Kool Mar 26 '18 at 10:09
@AndréKool can i find username when i have only uid ("Sk6I...") ? – Volodymyr Humeniuk Mar 26 '18 at 10:10
For that take a look at [this answer](https://stackoverflow.com/a/49460112/4916627) on your other question – André Kool Mar 26 '18 at 10:17
Do you mean you want to change the `TestName` value?. I am not clear about your logic. – Hareesh Mar 26 '18 at 10:37
@Hareesh yes, but TestName its a key, and i can't edit this, so i want remove it and create new object – Volodymyr Humeniuk Mar 26 '18 at 10:40
May be you need to fetch the object you want to delete, then set null in that path. – Chandrika Mar 26 '18 at 12:00
