mongoose & ember，记录被拒绝原因：typeerror

Question

我在回复中收到此类型错误，但我不知道 store.find('someThread') 期望什么格式。 这是我的余烬部分：

App.RestAdapter = DS.RESTAdapter.extend({
  url: 'http://mylocalhost:3000',
  namespace: 'api',

  serializer: DS.RESTSerializer.extend({
    primaryKey: function(type) {
        return '_id';
    }
  })
});

App.Store = DS.Store.extend({
  revision: 12,
  adapter: App.RestAdapter
});

App.VideoRoute = Ember.Route.extend({
  model: function() {
    console.log("video..", this.store.find('video'));
    return true;
  }
});

这是节点部分：

exports.list = function(req, res) {
  Video.find(function(err, videos) {
    var payload = { video: {name: "sampleName"}};
    return res.send(200, JSON.stringify(payload));
  });
}

这是响应的 console.log：

Class {constructor: function, reason: null, isPending: undefined, isSettled: undefined, isRejected: false…}
  __ember1385638132476: undefined
  __ember1385638132476_meta: Meta
  _super: undefined
  arrangedContent: (...)
  content: (...)
  isRejected: true
  reason: TypeError
  message: "Object function () {↵    if (!wasApplied) {↵  (...)"
  stack: (...)
  get stack: function () { [native code] }
  set stack: function () { [native code] }
  __proto__: Error
  __proto__: Object

如果我只发送一个字符串，我确实会收到响应：`res.send("something"); 但这只是在responseText中，isRejected是真的，所以...

有什么想法吗？

更新 2：

发现您可以覆盖 ajax 方法。现在，至少我知道，json 是在成功函数上传输的，但数据属性仍然未定义......

App.ApplicationAdapter = DS.RESTAdapter.extend({
  url: 'http://localhost:3000',
  namespace: 'api',

  ajax: function(url, type, hash) {
   var adapter;
   adapter = this;
   return new Ember.RSVP.Promise(function(resolve, reject) {
    var headers;
    hash = hash || {};
    hash.url = url;
    hash.type = type;
    hash.dataType = "json";
    hash.context = adapter;
    if (hash.data && type == "GET") {
      hash.contentType = "application/json; charset=utf-8";
      hash.data = JSON.stringify(hash.data);
    }
    if (adapter.headers !== undefined) {
      headers = adapter.headers;
      hash.beforeSend = function(xhr) {
        return forEach.call(Ember.keys(headers), function(key) {
          return xhr.setRequestHeader(key, headers[key]);
        });
      };
    }
    hash.success = function(json) {
      console.log("success", hash.data, json); //-> undefined, Object {video: Object}
      return Ember.run(null, resolve, json);
    };
    hash.error = function(jqXHR, textStatus, errorThrown) {
      return Ember.run(null, reject, adapter.ajaxError(jqXHR));
    };
    return Ember.$.ajax(hash);
  });
 },
});

如果你使用的是 ember-data 1.0.0-beta.x 版本，你需要像下面这样声明你的适配器和序列化器：

App.ApplicationSerializer = DS.RESTSerializer.extend({
  primaryKey: '_id'
});

App.ApplicationAdapter = DS.RESTAdapter.extend({
  url: 'http://mylocalhost:3000',
  namespace: 'api'
});

App.VideoRoute = Ember.Route.extend({
  model: function() {
    console.log("video..", this.store.find('video'));
    return true;
  }
});

有一个转换指南here，它告诉我们 0.13 和 1.0.0-beta.x 版本之间的变化是什么
