Ember-Data可以从一个JSON有效载荷处理两个模型吗？ [英] Can Ember-Data handle two models from one JSON payload?

问题描述

我的JSON来自服务器，如下所示：

I have JSON coming from the server which looks like:

data: {
       user: {
              address: {
                         id: "id",
                         city: "city",
                         street: "street",
                         .......
              }
              name: "name",
              ......
       }

       authentication-token: {
                         token: "token",
                         id: "id"
       }
}

将这两个模型（用户，身份验证令牌）存储在同名的ember store中。当我从服务器获取上述响应时，模型用户被成功保存，但是模型认证令牌根本不会保存到存储。当我将数据（在适配器中）记录在数据传递给序列化程序之前，我看到JSON具有Ember-Data期望的结构。我不知道问题是Ember-Data不能一次处理两个模型成功，然后将其保存到相应的模型，或者其他的。想法？

The idea is to store this two models (user, authentication-token) in ember store under the same names. When I gat the above mentioned response from a server, model user is saved successfully, but model authentication-token does not get saved to the store at all. When I log the data (in the adapter) before the data is passed to serializer I see that JSON has a structure which Ember-Data expects. I don't know whether the problem is that Ember-Data cannot handle two models in success at one time, and then save it to the corresponding models, or something else. Ideas?

推荐答案

现在 it 都对我有意义。当然，这是您的最后一个问题。无论如何，ember数据的RESTAdapter无法处理。如果您要求一个单一的资源用户，它最多希望这个用户是一个单一的答案。任何其他资源可能都是side-loaded必须是一个数组。请求的单数用户可以是用户键下的记录或数组中的第一个条目取消用户键。其他（元数据除外）必须是复数。

Now it all makes sense to me. Of course, this was the problem in your last question. Anyway, ember-data's RESTAdapter can't handle this. If you're requesting a singular resource user it expects at most this user as a singular answer. Any other resource that may be "side-loaded" has to be an array. The requested singular user can either be a record under the user key or the first entry in an array unter the users key. Everything else (except meta data) has to be plural.

如果您要求复数资源用户主要响应必须在用户之下，任何不属于 _ _users 键。

In case you're requesting a plural resource users, the main response must be under the users key, any sideloaded users that aren't part of the response prfixed with _ under the _users key.

对于你的例子，这意味着你的json必须格式如下： / p>

For your example all this means that your json must be formatted like this:

data: {
       user: {
              address: {
                         id: "id",
                         city: "city",
                         street: "street",
                         .......
              }
              name: "name",
              ......
       }

       authentication-tokens: [{
                         token: "token",
                         id: "id"
       }]
}

如果您无法更改服务器，确定RESTAdapter通过规范化来规范化JSON数据串行器。

If you can't change your server, you'd have to configure the RESTAdapter to normalize the JSON data through normalize of the Serializer.
