在过去的几天里，我一直在研究我的应用程序，试图找出如何最好地跟踪给定控制器中的编辑状态。当然，问题是，这些 ObjectController 一次存在多个，并且在给定时刻只能编辑一个。下面是重要的代码：

应用程序.js：

var App = Ember.Application.create();

//ROUTES
App.Router.map(function() {
  this.resource('tasks', function() {
    this.resource('task', {path: ':task_id'});
  });
});

App.IndexRoute = Ember.Route.extend({
  redirect: function() {
    this.transitionTo('tasks');
  }
});

App.TasksRoute = Ember.Route.extend({
  model: function() {
    return App.Task.find();
  }
});

App.TaskRoute = Ember.Route.extend({});

//CONTROLLERS
App.TasksController = Ember.ArrayController.extend({
  isEditing: null,
  editing: false,
  newTask: function() {
    console.log('new task');
  },
  toggleEdit: function(id) {
    this.set('isEditing', id);
    if ($('#collapse' + this.get('isEditing')).hasClass('in')) {
      this.set('editing', false);
      this.set('isEditing', null);
      $('.in').collapse('hide');
    } else {
      this.set('editing', true);
      $('.in').collapse('hide');
      $('#' + 'collapse' + this.get('isEditing')).collapse('toggle');
    }
  }
});

App.TaskController = Ember.ObjectController.extend({
  needs: 'tasks',
  collapseId: function() {
    return "collapse" + this.get('id');
  }.property('id'),
  collapseHref: function() {
    return  "#collapse" + this.get('id');
  }.property('id'),
});

//VIEWS
App.ApplicationView = Ember.View.extend({
  didInsertElement: function() {
    var self = this;
    Ember.run.schedule('afterRender', function() {
      self.$('.navbar').affix({offset: -1000});
    });
  }
});

//HANDLEBARS HELPERS

//STORE DEFINITION
App.Store = DS.Store.extend({
  revision: 11,
  adapter: 'DS.FixtureAdapter'
    /*DS.RESTAdapter.extend({
      url: 'http://localhost:3000'
    })*/
});


//MODELS
App.Task = DS.Model.extend({
  summary: DS.attr('string'),
  description: DS.attr('string'),
  start: DS.attr('string'),
  end: DS.attr('string'),
  recurrence: DS.attr('string')
});

//FIXTURE DATA
App.Task.FIXTURES = [{
  id: "q5ji9chrh1hcu05dohvrf4aumc",
  summary: "Test",
  description: null,
  start: "2013-04-01T10:00:00-07:00",
  end: "2013-04-01T11:00:00-07:00",
  recurrence: "FREQ=WEEKLY;BYDAY=MO,WE,TH,FR"
}, {
  id: "mm4m3pq6icbgbl6m49jpdhi8j0",
  summary: "Test 2",
  description: "absafdaerwer",
  start: "2013-04-01",
  end: "2013-04-02",
  recurrence: null
}];

TaskController我相信在这段代码中，没有创建多个s。尝试itemController: 'task'在ArrayController. （在此处讨论，如果您正在使用，请参见此处1.0.0-rc.2提及。）这样您就可以在该特定任务上设置一个属性（如果ed 则参考）。这能澄清什么吗？editingtasksneed
