我对ember很新，但我想知道这是不是我的逻辑问题，或者是否有什么东西在ember中无法正常运行。
当我尝试model.get('profile')时，我得到了空。
我能够像这样检索一个配置文件模型：
this.store.find('profile', 17);
此外，我可以将profile_id属性添加到位置模型，然后使用它
var location = this.modelFor('location');
var profile = this.store.find('profile', 17);
但是根据我在文档中可以找到的内容，我应该可以在位置对象上使用.get('profile')来获取其配置文件。
奇怪的是，我的附件关系（位置有很多附件）完美无缺。
我错过了什么吗？我做错了什么导致这种关系失败？
我有三种模式：
locatons-＆GT;
export default DS.Model.extend({
image: DS.attr('string'),
latitude:DS.attr('string'),
longitude:DS.attr('string'),
outlets:DS.attr('string'),
parking:DS.attr('string'),
internet:DS.attr('string'),
credit_cards:DS.attr('string'),
share_url:DS.attr('string'),
roaster:DS.attr('string'),
about:DS.attr('string'),
name: DS.attr('string'),
address: DS.attr('string'),
images: DS.attr('string'),
attachments: DS.hasMany('attachment'),
profile: DS.belongsTo('profile'),
curator_image: DS.attr('string'),
curator_about: DS.attr('string'),
curator_name: DS.attr('string'),
style_image_url: function(){
return "background-image:url('" + this.get("image") + "')";
}.property("image"),
style_profile_image_url: function(){
return "background-image:url('" + this.get("curator_image") + "')";
}.property("curator_image"),
});
附件 - ＆gt;
export default DS.Model.extend({
location: DS.belongsTo('location'),
image:DS.attr('string')
});
个人资料 - ＆gt;
export default DS.Model.extend({
location: DS.hasMany('location'),
name:DS.attr('string'),
about:DS.attr('string'),
image:DS.attr('string'),
});
这是来自服务器的示例响应： locations.json

路线： /routes/location.js
export default Ember.Route.extend({
model: function(params) {
return this.store.find('location', params.location_id);
}
});
/路由/位置/索引
export default Ember.Route.extend({
model: function() {
return this.modelFor('location').get('profile');
}
});
更新： 通过将我的json更改为：
，我能够获得配置文件模型{

将我的位置对象保存到我的window.loc路由中，然后检入浏览器控制台：
loc.get('profile').get('name')
返回"Jack White"这是正确的，但我不清楚为什么这个变化会产生影响。边加载（放置相关对象的id并包括这些对象的顶级数组）是否仅适用于ember数据中的一对多关系？
欢迎任何和所有输入，我仍然是新的数据。

locations.json中没有侧载的个人资料对象，就像附件一样。看起来应该更像：
{
locations: [{
id: 12,
...
profile_id: 17,
attachment_ids: [...]
}],
attachments: [...],
profiles: [...] /* for multiple profiles, or*/
profile: {...} /* for a single side-loaded model */
}
...
否则，如果您要异步加载profile模型，则需要在location模型中声明它，如下所示：
profile: DS.belongsTo('profile', {
async: true
}

我发现解决方案是在json中将profile_id: xx重命名为profile: xx。我假设model_id是注意所属关系的正确方法，但事实证明，ember只需要模型名称。希望这有助于将来的某个人！

我可能在这里愚蠢，但您的位置模型没有个人资料字段 - 可能是因为它属于个人资料。但是，如果没有该字段，您将无法在位置上执行.get（＆＃39; profile＆＃39;）。
