我一直收到DS.FixtureAdapter未定义错误。我不知道如何解决这个错误。我在使用App.PersonAdapter = DS.FixtureAdapter.extend（{}）获取错误;
这是app.js代码。
App = Ember.Application.create();
App.Router.map(function() {
// put your routes here
});
App.PersonAdapter = DS.FixtureAdapter.extend({});
App.Person = DS.Model.extend({
firstName: DS.attr(),
lastName: DS.attr(),
age: DS.attr()
});
App.IndexRoute = Ember.Route.extend({
model: function() {
return this.store.find('person');
}
});
App.Person.FIXTURES = [
{
id: 1,
firstName: 'John',
lastName: 'Doe',
age: 39
},
{
id: 2,
firstName: 'Jane',
lastName: 'Doe',
age: 29
}
]
