主要成分：从服务器上获取集合 [英] Backbone: fetch collection from server

问题描述

我想从我的服务器获取的集合。
我使用的版本0.3.3（不是从GitHub主）
但是我在这个异常运行：

I'm trying to fetch a collection from my server. I'm using version 0.3.3 (not the master from github) However I am running in this exception:

Uncaught TypeError: Cannot use 'in' operator to search for 'id' in {id=MyId, active=true}
    jQuery.jQuery.extend._Deferred.deferred.resolveWith (jquery.js:869)
    done (jquery.js:6591)
    jQuery.ajaxTransport.send.callback

这是我创建的错误的方式：

This is the way I created the error:

var MyModel = Backbone.Model.extend();
var MyCollection = Backbone.Collection.extend({
    url: '/api/collection',
    model: MyModel
});
var coll = new MyCollection();
coll.fetch();

在/ API / Collection中的元素被解析的JSON。
我试图以各种格式返回它们

The elements in /api/collection are parsed in JSON. I tried to return them in various formats

["Id1", "Id2", ... ]
[{id: "Id1, somethingElse: "..."}, ...]
{id1: { id1s content}, id2: { ... }, ...}

然而误差总是相同的。
有什么不对这个code？

However the error was always the same. What is wrong with this code?

它不利于通过设置 coll.fetch（{错误：errorFunc}）的错误; 除外住宿相同。

It doesn't help to set an error via coll.fetch({error: errorFunc}); The Exception stays the same.

好了，似乎一切都很正常，直到 collection.fetch（）通话 collection.refresh（） 与响应对象。我没有任何覆盖这些功能。

Well it seems everything works fine until collection.fetch() calls collection.refresh() with the response object. I have not overwritten any of these functions.

的错误是在 collection.add（）方法的原因是，我的元素是字符串列表。 ..我的服务器发送他们错了。

The error is in the collection.add() method and the reason is that my elements are a list of strings... My server sent them wrong.

推荐答案

而不是

["id1", "id2", ..., "idn"]

客户端希望

[{"id": "id1"}, ... {"id": "idn"}]
