Backbone.js 茉莉花试验

更新：

我有一个简单的主干关系模型：

@App.M.Product = Backbone.RelationalModel.extend
    defaults: {}
    url: App.D.dataURL
    relations: [
        {
            type: Backbone.HasMany
            key: 'templates'
            relatedModel: 'App.M.Template'
            collectionType: 'App.C.Templates'
            reverseRelation:
                key: 'product'
        }
        {
            type: Backbone.HasMany
            key: 'pages'
            relatedModel: 'App.M.Page'
            collectionType: 'App.C.Pages'
            reverseRelation:
                key: 'product'
        }
        {
            type: Backbone.HasMany
            key: 'uploaded_images'
            relatedModel: 'App.M.UploadedImage'
            collectionType: 'App.C.UploadedImages'
            reverseRelation:
                key: 'product'
        }
    ]
    initialize: ->
        if @get('minimumNumberOfPages') < 1
            @set 'minimumNumberOfPages', 1
    fixPages: ->
        col = @get 'pages'
        col.each (page) ->
            page.collection = col

但是，模型未能初始化（取自testem的终端输出）：

为什么呢？应用程序运行正确，测试不正确。

因此错误为

参考错误：产品未定义。这是因为您在

函数之前的和测试中的中定义了它，因此这两个函数不相同，测试中未定义。您必须在描述块中定义它：

“严格使用”

描述‘产品’，-> product=null

beforeEach ->
    product = new App.M.Product

it 'should be defined', ->
    expect(product).toBeDefined()

---

对于另一个错误

TypeError:cannotreadproperty'prototype'of undefined

，您似乎没有在

collectionType

下添加集合。因此，插件正在全局名称空间中查找

App.C.Pages

，并尝试获取对象的原型。但正如错误所说，它没有定义

谢谢，这对第一部分很有帮助。其余的呢？
