【问题描述】:
我正在尝试使用 ember.js 和 ember-data 创建一个应用,使用以下版本:
DEBUG: Ember : 1.7.0
DEBUG: Ember Data : 1.0.0-beta.9
DEBUG: Handlebars : 1.2.1
DEBUG: jQuery : 2.1.0
我正在使用 RESTAdapter 连接到我使用 node.js 编写的 api。
一旦我加载应用程序,我就会不断收到以下错误:
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)
这是我正在使用的代码(按照我粘贴它的相同顺序加载):
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();
}
})
});
models/student.js
App.Student = DS.Model.extend({
firstName: DS.attr('string'),
lastName: DS.attr('string'),
nationality: DS.attr('string'),
createdAt: DS.attr('date')
});
routes/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的响应:
{
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 数据格式看起来不错。知道可能出了什么问题吗?
谢谢!

我想我有完全相同的错误,当我没有使用 1.7.0 而是 1.8.0-beta.1 时开始......切换回 1.7.0 为我修复了它。不知道为什么你会遇到这个问题:(

我相信您需要在
primaryKey中使用字符串而不是函数based on the docs。类似primaryKey: '.
