试图用mysql测试compoundjs但它失败了.

我的系统是Debian 7,其中包含以下版本的nodejs和npm

$ node -v
v0.10.13

$ npm -v
1.3.4

这是我安装compoundjs的方法

sudo npm install -g compound
sudo npm install -g jugglingdb --save
sudo npm install -g jugglingdb-mysql

compound init testapp --db mysql
cd testapp
npm install

$ node server.js

WARNING: JugglingDB adapter "mysql" is not installed,
so your models would not work, to fix run:

    npm install jugglingdb-mysql


/srv/www/playground/node/testapp/node_modules/jugglingdb/lib/railway.js:55
        if (!schema.adapter) throw new Error('Adapter is not defined');
                                   ^

我有关系数据库的用户模型.

每个用户都可以拥有"chiefId"为FK的"用户".

"relations": {
    "users": {
      "type": "hasMany",
      "model": "User",
      "foreignKey": "chiefId"
    },
}

我可以查询每个主要用户的相关用户,如下所示:

GET /users?filter={"include":"users"}

但它返回完整的用户对象.

• 我该如何仅查询相关用户的"名称"属性？
• 是否可以在一个请求中计算相关实例到服务器？
