Modeling Your Data

为数据建立模型

Next we will create a model class to describe todo items.

接下来我们建立一个模型用来描述todo项。

Create a file at js/models/todo.js and put the following code inside:

新建一个名为 js/models/todo.js 的文件,加入以下代码:

  1. Todos.Todo = DS.Model.extend({
  2. title: DS.attr('string'),
  3. isCompleted: DS.attr('boolean')
  4. });

This code creates a new class Todo and places it within your application’s namespace. Each todo will have two attributes: title and isCompleted.

这段代码创建了一个新的 Todo 类,并将它置于你应用的命名空间下。每一个todo有两个属性: titleisCompleted

You may place this file anywhere you like (even just putting all code into the same file), but this guide will assume you have created a file and named it as indicated.

你可以将这个文件放在任意你喜欢的地方(甚至把它们所有的代码放在同一个文件内),但是本指南假定你创建了一个文件并按照前面讲的进行命名。

Finally, update your index.html to include a reference to this new file:

最后,更新 index.html ,将下列引用添加到这个新文件中:

  1. <!-- ... additional lines truncated for brevity ... -->
  2. <!-- ... 为确保简洁,略去头尾代码 ... -->
  3. <script src="js/models/todo.js"></script>
  4. </body>
  5. <!-- ... additional lines truncated for brevity ... -->
  6. <!-- ... 为确保简洁,略去头尾代码 ... -->

Reload your web browser to ensure that all files have been referenced correctly and no errors occur.

重新加载浏览器页面,确保所有的文件被正确引用,且没有错误产生。
