Differentiating current logged in user and other users


How do people usually handle this problem in DS.Model? The model is probably both called User, but there are significant difference in what they can do and probably different attributes.


You could inject the currently logged in user into all controllers and routes. Then you can always do the check if a user is the currentUser.



I’m currently in the midst of writing a little post about how I solved this today but the gist of it is this:

I made a mixin that fetches some preloaded JSON from a meta-tag (but you could just as well GET api/users/me or something like that) and stores it on the ApplicationController. The code looks roughly like this:

LS.CurrentUserMixin = Ember.Mixin.create({
  needs: ['application'],

  init: function () {

    if (!this._application().get('currentUser')) {
      var payload = this._rawUserData();
      this.store.pushPayload('user', { user: payload.user });
                              this.store.getById('user', payload.user.id));

  currentUser: function () {
    return this._application().get('currentUser');

  // private

  _application: function () {
    return this.get('controllers.application');

  _rawUserData: function () {
    return JSON.parse($('meta[name="current-user"]').attr('content'));

Then you could use this in your controllers like so:

LS.UserIndexController = Ember.ObjectController.extend(  
  LS.CurrentUserMixin, {

  isCurrentUser: function () {
    return this.get('currentUser') === this.get('model');

Hope that helps, if anyone has any tips I’d love to hear them ^^
