  #scenario 1 /orgs/17/settings
  OrganizationRoute = Em.Route.extend

      model = Organization.find(params.organization_id)
      @controllerFor('organizations').set 'selectedModel', model

    needs: 'organization'
    organization: null 
    organizationBinding: 'controllers.organization'
    editOrg: ->

  #scenario 2 /orgs/17/settings
  OrganizationRoute = Em.Route.extend
    model: (params) ->
      model = Organization.find(params.organization_id)
      #@controllerFor('organizations').set 'selectedModel', model
      
  OrganizationSettingsController = Em.Controller.extend
    needs: 'organization'
    organization: null 
    organizationBinding: 'controllers.organization'
    editOrg: ->
      console.log @get('model') #=> undefined
      console.log @organization.get('id') #=> 17
      console.log @organization.get('model') #=> {id: "17", store: Class, _reference: Object, _changesToSync: Object, transaction: Class…}
  

Here you go fo the first example:

#scenario 1 /orgs/17/settings
App.OrganizationRoute = Em.Route.extend
  model: (params) ->
    (require 'organization').find params.organization_id

  setupController: (controller, model) ->
    @_super arguments...
    @controllerFor('organizations').set 'selectedModel', model

App.OrganizationSettingsController = Em.Controller.extend
  needs: 'organization'
  organization: null 
  organizationBinding: 'controllers.organization'
  editOrg: ->
    console.log @get('organization.id')
