无法获得与ember数据相关的关系(Cannot get relationships working with ember data)

编程入门行业动态更新时间:2024-10-24 14:17:30

我正在使用RESTAdapter的ember-data。

我有一个旅游模块：

DS.Model.extend({ title: DS.attr('string'), trips: DS.hasMany('trip') });

这是用REST json填充的：

[{ id: 132, title: 'Tour title', },...]

和Trips的模块：

DS.Model.extend({ tour: DS.belongsTo('tour'), startDate: DS.attr('date') });

这是用REST json填充的：

{ id: 12345, tour_id: 132, startDate: '2013-01-01', }

我想这样，当使用旅行模型时，我可以打电话给trip.tour.title来获得旅行的标题。分别我可以制作tour.trips以获得所有旅行的列表。

但不知何故，这不起作用任何关系用法甚至不会触发ajax请求。所以我想知道为什么？所有属性都已正确映射，但不是关系。

请指教。

I am using ember-data with RESTAdapter.

I have a module for Tours:

DS.Model.extend({ title: DS.attr('string'), trips: DS.hasMany('trip') });

this is populated with REST json:

[{ id: 132, title: 'Tour title', },...]

and a module for Trips:

DS.Model.extend({ tour: DS.belongsTo('tour'), startDate: DS.attr('date') });

this is populated with REST json:

{ id: 12345, tour_id: 132, startDate: '2013-01-01', }

I would like so that that when using trip model I could call trip.tour.title to get a title of the tour. And respectively I could make tour.trips to get a list of all trips for the tour.

But somehow this is not working any relationships usage don't even trigger an ajax request. So I wonder why? All the properties are mapped correctly, but not relationships.

Please advice.
