Question

我第一次使用django-rest-framework api。这是我的问题：

我需要设计一个有两个表的数据库：

服务器=＆gt;保存服务器信息，如IP地址和服务器名称

id: INT, name: VARCHAR, ip_address: VARCHAR

Deploy =＆gt;服务器上的部署包括部署日期和注释消息

id: INT, server_id: FK to Server, deploy_date: DATETIME, message: VARCHAR

我被要求跟踪部署信息并设计以下API：

get /servers/ => get all the server information with the latest deploy on that server
Example:
[
  {
    "id" : 1,
    "name" : "qa-001",
    "ip_address" : "192.168.1.1",
    "deploy" : 
    {
      "id" : 1,
      "deploy_date" : "2013-09-09 12:00:00",
      "message" : "test new api"
    }
  },
  {
    "id" : 2,
    "name" : "qa-002",
    "ip_address" : "192.168.1.2",
    "deploy" : 
    {
      "id" : 2,
      "deploy_date" : "2013-09-10 12:00:00",
      "message" : "test second message"
    }
  }
]

get /deploys/ => get all the deploy information
Example:
[
  {
    "id" : 1,
    "deploy_date" : "2013-09-09 12:00:00",
    "message" : "test new api",
    "server_id" : 1
  },
  {
    "id" : 2,
    "deploy_date" : "2013-09-10 12:00:00",
    "message" : "test second message",
    "server_id" : 2 
  },
  {
    "id" : 3,
    "deploy_date" : "2013-09-08 12:00:00",
    "message" : "test new api",
    "server_id" : 1
  }
]
// Deploy 3 does not show up in the get servers return json 
// because deploy 1 was deployed on the same server but later than deploy 3.

POST /deploys/ => To insert a new deploy
POST /servers/ => To insert a new server
...

我玩过django-rest-framework教程代码并阅读了不同的api文档，但无法弄清楚如何实现我上面列出的功能。

如果您对如何实现这一点或者您认为其他数据库设计更符合此要求，请告诉我。

谢谢！
