In controller:

App.DashboardController = Ember.Controller.extend
  workspaces: []
  currentWorkspace: null //set by /workspace/:id route

  fetch: ->
    //ajax load workspaces

  

In old router:
  connectOutlets: ->
     controller.connectOutlet 'main', 'workspaces', controller.workspaces

DashboardView:
{{outlet main}}

WorkspacesController is ArrayController, containing all workspaces

WorkspacesView template:

{{each controller itemViewClass="WorkspaceView"}}

Workspace view template:
<div {{bindAttr class="this.active"}}>Some content for single workspace</div>

Now, the workspace model, in old router:

Workspace = Ember.Object.extend
 active: ->
  App.router.get('dashboardController.currentWorkspace.id') == this.id



If '/' url is selected, list of workspaces is shown, none of them is active.
If '/workspace/:id' url is selected, list of workspaces is displayed, one of
them with different color, and content of that workspace is bound to one of the outlets.


In model view:

{{#if active}}
Content for 'active' model
{{/if}}
{{#unless active}}
Content for 'inactive' model
{{/unless}}


So, because of there is no {{#if a == b}} construct, I need to have this whole 'active' and 'currentWorkspace' mess.
That mess require that either model or view (depending where 'active' property is defined) has access to controller.

Is there any better solution?
