我尝试使用以下版本使用ember.js和ember-data创建应用:
DEBUG: Ember : 1.7.0
DEBUG: Ember Data : 1.0.0-beta.9
DEBUG: Handlebars : 1.2.1
DEBUG: jQuery : 2.1.0
我使用RESTAdapter连接到我使用node.js编写的api。
加载应用后,我不断收到以下错误:
Error while processing route: students undefined is not a function TypeError: undefined is not a function

at apply (http://localhost:9000/scripts/vendor/ember.js:18382:27)
这是我使用的代码(按照我粘贴的相同顺序加载):
app.js
var App = window.App = Ember.Application.create({
LOG_ACTIVE_GENERATION: true,
LOG_TRANSITIONS: true,
LOG_TRANSITIONS_INTERNAL: false,
LOG_VIEW_LOOKUPS: true
});
store.js
App.ApplicationAdapter = DS.RESTAdapter.extend({
host: 'http://localhost:3000',
serializer: DS.RESTSerializer.extend({
primaryKey: function(type) {
return '_id';
},
serializeId: function(id) {
return id.toString();
}
})
});
模型/ student.js
App.Student = DS.Model.extend({
firstName: DS.attr('string'),
lastName: DS.attr('string'),
nationality: DS.attr('string'),
createdAt: DS.attr('date')
});
路由/ app_route.js
App.StudentsRoute = Ember.Route.extend({
model: function() {
return this.store.find('student');
}
});
router.js
App.Router.map(function () {
this.resource('students', {path: '/'});
});
以下是API的回复:
{
students: [
{
nationality: "Lorem",
lastName: "Doe",
firstName: "John",
_id: "53f87200f3750319b4791235",
createdAt: "2014-08-23T10:50:40.661Z"
},
{
nationality: "Lorem",
lastName: "Doe",
firstName: "John",
_id: "53f87299f3750319b4791234",
createdAt: "2014-08-23T10:50:40.661Z"
}
]
}
看起来商店没有从API加载数据,但JSON数据格式看起来很好。知道什么可能是错的吗?
谢谢!

所以在Stack Overflow上搜索了更多内容后,我发现序列化程序现在必须与RESTAdapter分开,所以工作代码如下:
<强> store.js 强>
App.ApplicationAdapter = DS.RESTAdapter.extend({
host: 'http://localhost:3000'
});
App.ApplicationSerializer = DS.RESTSerializer.extend({
primaryKey: '_id',
serializeId: function(id) {
return id.toString();
}
});

以下是使用ember-cli
的人的更新答案。
ember g adapter application #=> creates app/adapters/application.js
ember g serializer application #=> creates app/serializers/application.js
在app/adapters/application.js
:
import DS from 'ember-data';
export default DS.RestAdapter.extend({
host: 'http://localhost:3000'
});
在app/serializers/application.js
:
import DS from 'ember-data';
export default DS.RESTSerializer.extend({
primaryKey: '_id',
serializeId: function(id) {
return id.toString();
}
});

我收到了这个错误,它与任何常见的嫌疑人无关。
在coffeescript中,我开始定义一个模型。
App.Cost = DS.Model.extend
amount: DS.attr 'number'
active: DS.attr 'boolean'
要创建第二个模型,我可以使用我的第一个模型并删除属性:
App.Cost = DS.Model.extend
回过头来试图运行一个看似无关的模型
localhost:3000/products
导致错误
Error while processing route: products.index
只需确保我的模型被正确命名即可解决错误:
App.Cost = DS.Model.extend(...)
App.Price = DS.Model.extend(...) <- instead of repeating the Cost model
这是可以重复制作的,所以我认为它可能对其他人有帮助。
