私は次のモデルを持っています：
this.store.find('history'); を呼び出すと、
http:://www.example.com/api/history/ への呼び出しが行われ、次の JSON 応答が返されます。

これで、Store.History と Store.Track の両方のレコードが保存されます (下のスクリーンショットを参照)。
ただし、 Store.History からレコードを確認すると、「トラック」属性は null を返します
Store.Track レコードを確認しましたが、これらには JSON の結果に表示されたのと同じ ID が含まれています。
編集：リクエストごとに、これらは私のモデルです：
var attr = DS.attr,
belongsTo = DS.belongsTo,
hasMany = DS.hasMany;
Shoutzor.Album = DS.Model.extend({
artist: belongsTo('artist'),
title: attr('string'),
cover: attr('string')
});
Shoutzor.Artist = DS.Model.extend({
name: attr('string'),
profileimage: attr('string')
});
Shoutzor.User = DS.Model.extend({
name: attr('string'),
firstname: attr('string'),
email: attr('string'),
joined: attr('date'),
last_active: attr('date')
});
Shoutzor.Track = DS.Model.extend({
title: attr('string'),
length: attr('number'),
artist: hasMany('artist'),
album: hasMany('album'),
/* Convert the length in seconds to a string like '01:55' */
convertedLength: function() {
var sec_num = parseInt(this.get('length'), 10); // don't forget the second parm
var hours = Math.floor(sec_num / 3600);
var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
var seconds = sec_num - (hours * 3600) - (minutes * 60);
if (hours < 10 && hours > 0) {hours = "0"+hours;}
if (minutes < 10 && minutes > 0) {minutes = "0"+minutes;}
if (seconds < 10) {seconds = "0"+seconds;}
var time = ((hours != 0) ? hours + ':' : '') + ((minutes != 0) ? minutes +':' : '') + seconds;
return time;
}.property('length')
});
Shoutzor.History = DS.Model.extend({
track: belongsTo('track'),
user: belongsTo('user'),
time_played: attr('date'),
print_time: function() {
var d = new Date(this.get('time_played'));
var hours = (d.getHours() < 10 ? "0" : '') + d.getHours(),
minutes = (d.getMinutes() < 10 ? "0" : '') + d.getMinutes(),
seconds = (d.getSeconds() < 10 ? "0" : '') + d.getSeconds();
return hours + ":" + minutes + ":" + seconds;
}.property('time_played')
});
どんな助けでも大歓迎です。
