从 Mustache 模板访问嵌套主干模型属性 [英] Access Nested Backbone Model Attributes from Mustache Template

问题描述

我有一个 Backbone 模型，它的一个属性是对另一个 Backbone 模型的引用.例如，一个 Person 有一个对 Address 对象的引用.

I have one Backbone model which has an attribute that is a reference to another Backbone model. For example, a Person has a reference to an Address object.

Person
  FirstName
  LastName
  Address
    Street
    City
    State
    Zip

这些是扩展 Backbone 模型的类.那么，如果我构造一个如下所示的对象......

These are classes that extend the Backbone model. So, then if I construct an object like the following...

var address = new Address({ Street: "123 Main", City: "Austin" });
var person = new Person({ FirstName: "John", Address: address });

我似乎不知道如何在我的 Mustache 模板中访问它.

I cannot seem to figure out how to access it in my Mustache template.

Hi {{FirstName}}, you live in {{Address.City}}.

显然不起作用.当我查看 Firebug 的内部结构时，Address 是一个对象，而 City 是 Address 的属性对象中的一个属性.我找不到有关如何访问关联对象的这些属性的任何示例.

Obviously does not work. When I look at the internals in Firebug, Address is an object, but the City is an attribute within the attributes object of Address. I cannot find any examples of how to access these attributes of associated objects.

感谢您的帮助！谢谢！

推荐答案

尝试使用 Handlebars，一个基于具有嵌套属性支持的 Mustache.

Try using Handlebars, a templating engine based on Mustache with nested properties support.

然后就像{{Address/City}}一样简单.

如果您不想更改模板引擎，可以将 Address 对象的结果展平，并将它们作为属性直接传递给 Person.

If you don't want to change your templating engine, you can flatten results from Address object and pass them as properties directly on the Person.
