为什么在 Ember 中成功 deleteRecord 后出现错误

Question

我在调用 deleteRecord 然后保存到实体后收到此错误。我正在使用 DS.RESTAdapter 和 delete 在后端运行良好，但控制台抛出此错误

Error: No model was found for 'id'
at new Error (native)
at Error.Ember.Error (http://localhost:3000/assets/ember.js?body=1:913:19)
at Ember.Object.extend.modelFor (http://localhost:3000/assets/ember-data.js?body=1:9808:33)

未捕获的错误：断言失败：错误：找不到“id”的模型

App.UserRoute = Ember.Route.extend({
    actions: {
        deletetag: function(params) {
            this.get('store').find('usertag', params.id).then(function(rec){
                rec.deleteRecord();
                rec.save();
            });
        }
    }

});

为什么 ember 试图返回名为“id”的模型的工厂实例？

谢谢！

愚蠢的错误。错误是从destroy方法返回的json缺少对象根。
