我有以下Ember.js模型:
Filters.Milestone = DS.Model.extend({
id: DS.attr('string'),
name: DS.attr('string')
});
在我的app.js中,我对模型有以下设置(在模型之前加载):
Filters.MilestoneSerializer = DS.RESTSerializer.extend();
Filters.MilestoneAdapter = DS.RESTAdapter.extend({
namespace: "ember"
});
加载页面时,会完成对里程碑列表的AJAX调用。返回以下JSON:
{
"milestones": [
{
"id": "1",
"name": "Test Milestone #1"
}
]
}
加载JSON时,会返回以下错误:
TypeError: Cannot call method 'hasOwnProperty' of undefined

我做错了什么?我尝试使用与https://github.com/emberjs/data/blob/master/packages/ember-data/tests/integration/adapter/rest_adapter_test.js#L465相同的结构。如果我重命名里程碑键,它说没有找到新键的模型,所以必须正确: - )
提前致谢。
我使用的路线如下:
Filters.FiltersRoute = Ember.Route.extend({
model: function() {
return this.store.find('milestone')
}
});
如果未调用this.store.find('milestone')
,则不会发生错误。此外,如果我使用FixtureAdapter
而不是RESTAdapter
,则仍会出现错误。所以看起来这可能与模型有关,而不是与数据源有关。
答案 0 :(得分:9)
问题是由模型中的id
属性引起的。显然,这不应该是模型的一部分。
