copied!<p><strong>UPDATED:</strong></p> <p>I have a simple Backbone-relational model:</p> <pre><code>@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 </code></pre> <p>and an even simplier test suite:</p> <pre><code>"use strict" describe 'Product', -> pr = null beforeEach -> pr = new App.M.Product it 'should be defined', -> expect(pr).toBeDefined() </code></pre> <p>However, the model fails to initialize (taken from testem's terminal output):</p> <pre><code>TypeError: Cannot read property 'prototype' of undefined at Backbone.HasMany.Backbone.Relation.extend.initialize (http://localhost:7357/app/bower_components/backbone-relational/backbone-relational.js:835:78) at Backbone.Relation (http://localhost:7357/app/bower_components/backbone-relational/backbone-relational.js:537:9) at new child (http://localhost:7357/app/bower_components/backbone/backbone-min.js:1:25220) at _.extend.initializeRelation (http://localhost:7357/app/bower_components/backbone-relational/backbone-relational.js:137:5) at null.<anonymous> (http://localhost:7357/app/bower_components/backbone-relational/backbone-relational.js:1176:31) at Array.forEach (native) at Function.w.each.w.forEach (http://localhost:7357/app/bower_components/underscore/underscore-min.js:1:599) at Backbone.RelationalModel.Backbone.Model.extend.initializeRelations (http://localhost:7357/app/bower_components/backbone-relational/backbone-relational.js:1175:6) at Backbone.RelationalModel.Backbone.Model.extend.set (http://localhost:7357/app/bower_components/backbone-relational/backbone-relational.js:1373:11) at Backbone.Model (http://localhost:7357/app/bower_components/backbone/backbone-min.js:1:3929) </code></pre> <p>Why is that? The app is wokring correctly, the tests are not.</p>
