Ember.JS中的动态计算属性已弃用？

// The Controller

Todos.Controller = Ember.Controller.create({

    // ** SNIP ** //

    countCompleted: function()
    {
        return this.get('todos').filterProperty('completed',truE).length
    }.property(),});

// The View

{{Todos.Controller.countCompleted.property}} Items Left

计算的属性仅在对象的create()函数中被弃用.如果要创建一个计算属性,则必须先扩展()对象,然后再创建()它.

例如：

// The Controller

Todos.TodosController = Ember.Controller.extend({

    // ** SNIP ** //

    countCompleted: function()
    {
        return this.get('todos').filterProperty('completed',});

// Note the lower case 't' here. We've made a new object
Todos.todosController = Todos.TodosController.create();

// The View


// We reference the created object here (note the lower case 't' in 'todosController')
{{Todos.todosController .countCompleted.property}} Items Left
