Backbone:从服务器获取集合 [英] Backbone: fetch collection from server

问题描述

我正在尝试从我的服务器获取一个集合.我使用的是 0.3.3 版(不是来自 github 的大师)但是我在这个异常中运行:

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();

/api/collection 中的元素以 JSON 格式解析.我尝试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: { ... }, ...}

但是错误总是一样的.这段代码有什么问题?

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

[Edit] 通过 coll.fetch({error: errorFunc}); 设置错误没有帮助，异常保持不变.

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

[Edit2] 好吧，似乎一切正常，直到 collection.fetch() 使用响应对象调用 collection.refresh().我没有覆盖任何这些功能.

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

[Edit3] 错误出在 collection.add() 方法中，原因是我的元素是字符串列表...我的服务器发送了它们错了.

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

代替

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

客户期望

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