How to store the user in a session


I am trying to set up ember-simple-auth with a django-rest-framework backend, but I'm running into some trouble saving the user to the session. I have to be able to do something like this in my templates:

<h2>Welcome back, {{session.user}}</h2>

So following several guides I found, I have got the authentication and authorization working so that I can get a valid token and use is in requests. To get the user on the session, I have modified App.CustomAuthenticator.authenticate so that when the token is returned, the username is also stored to the session:

authenticate: function(credentials) {
    var _this = this;
    return new Ember.RSVP.Promise(function(resolve, reject) {
            url: _this.tokenEndpoint,
            type: 'POST',
            data: JSON.stringify({username: credentials.identification, password: credentials.password }),
            contentType: 'application/json'
        }).then(function(response) {
                    token: response.token,
                    username: credentials.identification
        }, function(xhr, status, error) {
            var response = JSON.parse(xhr.responseText);

I then modified Application.intializer to give session a user property:

    name: 'authentication',
    before: 'simple-auth',
    initialize: function(container, application) {
        // register the custom authenticator and authorizer so Ember Simple Auth can find them
        container.register('authenticator:custom', App.CustomAuthenticator);
        container.register('authorizer:custom', App.CustomAuthorizer);
            user: function() {
              var username = this.get('username');
              if (!Ember.isEmpty(username)) {
                return container.lookup('store:main').find('user', {username: username});

However, when {{session.user.username}} is rendered it is just an empty string. My questions are:

  1. Is this really the best way to assigning a user to the session? It seems clumsy to me but I can't see anything better.
  2. I assume that the empty string is because a Promise is returned rather than a User object, so how to I resolve it?

With the latest release you can now specify a custom session class without having to reopen, see release note here: This is how it works:

App.CustomSession = SimpleAuth.Session.extend({
  account: function() {
    var accountId = this.get('account_id');
    if (!Ember.isEmpty(accountId)) {
      return this.container.lookup('store:main').find('account', accountId);
container.register('session:custom', App.CustomSession);
window.ENV['simple-auth'] = {
  session: 'session:custom',
