Question

我在我的Ember应用程序中为两个模型引入了一对多关联，我得到了这些相当神秘的错误：

[09:01:20.450] TypeError: type is undefined @ http://emberjs.com.s3.amazonaws.com/getting-started/ember-data.js:2284

我不确定我是否应该在DS.belongsTo('modelName')中大写，降低版本或降低模型名称，但是当它们被驼峰时我得到这个错误，其他套管得到'模型无法找到'错误所以我认为这是最好的错误。

我的模型和夹具数据：

// Models

App.ServiceProvider = DS.Model.extend({
    name: DS.attr('string'),
    email: DS.attr('string'),
    customers: DS.hasMany('customer')
});

App.Customer = DS.Model.extend({
    serviceprovider: DS.belongsTo('serviceProvider'),
    firstname: DS.attr('string'),
    lastname: DS.attr('string'),
    email: DS.attr('string')
});

// Fixtures

App.ServiceProvider.FIXTURES = [
 {
   id: 1,
   name : "Some Org.",
   email : "admin@someorg.com.au",
   customers : [1, 2]
 },
 {
   id: 2,
   name : "Some Co.",
   email : "admin@someco.com.au",
   customers : [3, 4]
 }
];

App.Customer.FIXTURES = [
 {
   id: 1,
   firstname : "John",
   lastname : "Smith",
   email : "admin@someorg.com.au",
   serviceprovider : [1]
 },
 {
   id: 2,
   firstname : "Jane",
   lastname : "Smith",
   email : "admin@someco.com.au",
   serviceprovider : [1]
 },
 {
   id: 3,
   firstname : "Jerry",
   lastname : "Smith",
   email : "admin@someco.com.au",
   serviceprovider : [2]
 },
 {
   id: 4,
   firstname : "Janet",
   lastname : "Smith",
   email : "admin@someco.com.au",
   serviceprovider : [2]
 }
];

我对Ember很新，任何见解都值得赞赏。

Answer 1

我只是想通了，问题是使用数组作为一对一关系的id。

这是有问题的装置

App.Customer.FIXTURES = [
 {
   id: 1,
   firstname : "John",
   lastname : "Smith",
   email : "admin@someorg.com.au",
   serviceprovider : [1]
 }
 ]

这是工作中的

 App.Customer.FIXTURES = [
 {
   id: 1,
   firstname : "John",
   lastname : "Smith",
   email : "admin@someorg.com.au",
   serviceprovider : 1
 }
 ]

Ember类型未定义＆amp;加载具有一对多关联的路由时出错
