Creating new users without resetting current user session - parse-platform

Question

In my Parse web app, I have a user management page that is accessible to administrators. This page allows admins to create new user accounts.
To create the accounts, I use Parse.User.signUp().
It works great, but it has the nasty side effect of resetting the current user session, which logs out the admin who created the new user account.
This is actually the documented behaviour of User.signUp():
This will create a new Parse.User on the server, and also persist the session in localStorage so that you can access the user using #current.
But I want to create new users without changing the current user. How do I do this?

Answer 1

Before creating the new user account with User.signUp, save the current user's sessionToken. Then, once the new user has been created, restore the session with User.become:
var sessionToken = Parse.User.current().getSessionToken();
Parse.User.signUp(username, password).then(function(newUser) {
Parse.User.become(sessionToken);
});

Answer 2

I can create a 'Parse Cloud' method that allows you use the 'Master Key' and call it from the SDK using the Cloud.
Parse.Cloud.define('salvarUsuario', function(request, response) {
var nomeCompleto = request.params.nomeCompleto;
var Email = request.params.Email;
var Username = request.params.Username;
var cpf = request.params.cpf;
var Password = request.params.Password;
var funcionarioBool = request.params.funcionarioBool;
var ativo = request.params.ativo;
var primeiroAcesso = request.params.primeiroAcesso;
var tipoAcesso = request.params.tipoAcesso;
var medicoBool = request.params.medicoBool;
//Parâmetros de controle
var fotoSelecionada = request.params.fotoSelecionada;
var usuario = new Parse.User();
usuario.set("nomeCompleto", nomeCompleto);
usuario.set("email", Email);
usuario.set("username", Username);
usuario.set("cpf", cpf);
usuario.set("password", Password);
usuario.set("funcionarioBool", funcionarioBool);
usuario.set("ativo", ativo);
usuario.set("primeiroAcesso", primeiroAcesso);
usuario.set("tipoAcesso", tipoAcesso);
usuario.set("medicoBool", medicoBool);
if(medicoBool) {
var medicoId = request.params.medico;
var Medico = Parse.Object.extend("Medico");
var medicoPointer = Medico.createWithoutData(medicoId);
usuario.set("medico", medicoPointer);
}
if(fotoSelecionada) {
var bytes = request.params.bytesFoto;
var file = new Parse.File("foto.png", bytes, "image/png");
usuario.set("foto", file);
}
usuario.save(null, {
useMasterKey: true,
success: function(salvoUsuario){
// The user was saved correctly
response.success("1");
},
error: function(error){
response.error("Erro ao criar novo usuário");
}
});
});
