我该如何从mvc3模型的序列化json中获取bone.js模型？ [英] How do I fetch a backbone.js model from serialized json from a mvc3 model?

问题描述

如果我在MVC3应用程序中有这样的模型：

If I had a model like this in my MVC3 application:

public class Person
{
    public Guid Id { get; set; }
    public Name Name { get; set; }
    public Address Address { get; set; }
    public PhoneNumber PhoneNumber { get; set; }
}

public class Name
{
    public string First { get; set; }
    public string Last { get; set; }
}

public class Address
{
    public string AddressLine { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string Zip { get; set; }
}

如何用填充它。fetch （）来自lobb.js？

How would do I populate it with .fetch() from backbone.js?

这是我尝试的方法：

class Person extends Backbone.Model

$ ->
    person = new Person()
    person.fetch()

    // person.get for things like Name.First, or Name, or First
    // all return undefined
    alert person.get( ... ) // ?

我有适当的JsonResult Action方法和控件，并已通过Fiddler验证了 fetch（）调用正确返回了Json数据。 （我明天早上可以在办公室张贴帖子）

I have the appropriate JsonResult Action method and control, and have verified with Fiddler that the fetch() call is properly returning the Json data. (Which I can post tomorrow morning from the office)

我真的是Backbone的新人，我在做什么错了？

I'm really new at Backbone, what am I doing wrong?

推荐答案

夫妇：1）提取是异步的。试试这个：

Couple things: 1) fetch is async. Try this:

person.fetch({
    success: function() {
        alert(person.get('Name')
    }
});

2）这将显示name属性是一个对象（但不是骨干模型）：

2) This will show that the name property is an object (but not a backbone model):

{
    Name: "Joe"
    etc...

}

您可能想要使用 Backbone的名字与您的关系相似。 。或者您可以覆盖解析来展平json。

You may want to use Backbone.Relational or something similar if you want Name to be a backbone model. or you can override parse to flatten out your json.
