How can I assign the first user in my Meteor app a specific role?

Question

I'm using meteor-roles for permissions, and I'd like to add a particular role to the first user created. I know I can't use addUsersToRoles in the onCreateUser hook because it queries the database for the user ID but the user has not been added to the database yet.

I found this answer suggesting wrapping the createUser method, but that doesn't work for me. The server complains that createUser doesn't support callbacks yet.

You can on the OnCreateUser , do something like this.

Accounts.onCreateUser(function(options, user) {
    //if there is not users on the database
    //we assign the First-User role
  if(Meteor.users.find().count() === 0){ 
     user.role = "First-User"
  }else{
     user.role = "normalUser"
   }
  return user;
});

Assuming you have the First-user role. like this.

Meteor.publish("First-User", function () {
  var user = Meteor.users.findOne({_id:this.userId});

  if (Roles.userIsInRole(user, ["First-User"])) {
    return Meteor.users.find({}, {fields: {emails: 1, profile: 1, roles: 1}});
  } 

  this.stop();
  return;
});

Remember you should call the onCreateUser at the top of the createUsers methods.

Note that the Roles.addUsersToRoles call needs to come after Accounts.createUser or Accounts.onCreate or else the roles package won't be able to find the user record (since it hasn't been created yet)

Hope this Works.
