ember-simple-auth deferReadiness，直到加载用户

Question

I am using ember-cli-simple-auth and have extended the session object to include the currentUser which is retrieved from the /me endpoint. However, when the page is reloaded and the user is logged in there is a delay until the logged in user information is loaded. I would like to defer the apps readiness until the user is retrieved.

I have this in a custom-session initializer.

import Session from 'simple-auth/session';
export default {
  name: 'custom-session',
  initialize: function(container, app) {
    var _app = app;
    var SessionWithCurrentUser = Session.extend({
        currentUser: function() {
            var _this = this;
            return this.container.lookup('store:main').find('me', '').then(function(data){
                _app.advanceReadiness();
                _this.set('currentUser', data);
            }, function(data){
                console.log('failed');
                return data;
            });
        }.property()
    });

    container.register('session:withCurrentUser', SessionWithCurrentUser);
    app.deferReadiness();
  }
};

It appears that advanceReadiness is never called so the app never loads. I am very new to ember and am still getting my head around the container so am unsure of how this works. What am I doing wrong?

Update

export default {
  name: 'custom-session',
  initialize: function(container, app) {
    var _app = app;
    var SessionWithCurrentUser = Session.extend({
        currentUser: function() {
            var _this = this;
            return _this.container.lookup('store:main').find('me', '').then(function(data){
                _app.advanceReadiness();
                _this.set('currentUser', data);
            }, function(data){
                console.log('failed');
                return data;
            });
        }.property()
    });

    var session = SessionWithCurrentUser.create();
    container.register('session:withCurrentUser', session, { instantiate: false });
    app.deferReadiness();
    session.currentUser();
  }
};

From the answer suggested I changed it to this but this gives the error undefined is not a function coming from the call to session.currentUser() .

You're never calling the currentUser method in the initializer. You'd need to change that to

var session = SessionWithCurrentUser.create()
container.register('session:withCurrentUser', session, { instantiate: false });
app.deferReadiness();
session.currentUser();

Of course you'd have to call app.advanceReadiness(); in the case where the user could not be loaded as well, otherwise the app would never start up in that case.
