node.js - 将 Mers 与 backbone.js 一起使用

Question

我有一个与 mers ( https://github.com/jspears/mers ) 一起运行的休息服务。

现在我想将它连接到 backbone.js

问题是 mers 返回包含在带有附加信息的有效负载数组中的集合:

例如

{"payload":[
{"_id":"4fe3773ffca7f74410000001","pos":[48.123447013691425,11.57250838808296],"username":"AyKarsi","pictures":[],"images":[],"roles":[],"meta":{},"groups":[]},
{"_id":"4fe3773ffca7f74410000002","pos":[0,3444],"username":"TestUpdateFromClient","pictures":[],"images":[],"roles":[],"meta":{},"groups":[]},],
"status":0,"total":5}

拥有这些信息很好，但我如何才能告诉 Backbone 集合它应该在哪里寻找模型？

Answer 1

您需要覆盖 Backbone.Collection 中的默认 parse 函数。

var MyCollection = Backbone.Collection.extend({
    parse: function(models) {
        return models.payload;
    }
}

这是 relevant documentation在 Backbone.js 网站上。
