Method call after register of accounts-ui in meteor

Question

I am using accounts-ui for login and registration in MeteorJS.

I want to add a role,on every newly registered user. I am using onCreateUser but it is throwing error Exception while invoking method 'createUser' Error:insert requires an argument Here is, what i am trying..

  Accounts.onCreateUser(function(options, user) {
        Roles.addUsersToRoles(user._id, ["Student"]);
        return user;
  });

Answer 1

I had the same problem. I use this code for adding default roles:

Accounts.onCreateUser(function(options, user) {
  if (options.profile) {
    user.profile = options.profile;
  }
  user.roles = ['student'];
  return user;
});
