How to hide sidebar in errror state


I would like to know if is possible to hide my sidebar in my application template in my error state.

I have in my application:

<aside class="sidebar">
<main class="main">

because in all my templates i have this sidebar, with exception of error.



I would wrap the sidebar with an {{#if showSidebar}}. Then when you enter your error state, applicationController.set('showSidebar', false).

In your template:

{{!-- templates/application.hbs --}}
{{#if showSidebar}}
  <aside class="sidebar">

In an error route:

// routes/error.js
export default Ember.Route.extend({
  activate() {
    this.controllerFor('application').set('showSidebar', false);

  deactivate() {
    this.controllerFor('application').set('showSidebar', true);

If you don’t have an error route you can use appController: Ember.inject.controller('application') in another controller to toggle the showSidebar.
