如何在Django模型中创建类属性的“关系”？

Question

{ '1': 
   Worker {
     domain: null,
     _events: { message: [Function] },
     _eventsCount: 1,
     _maxListeners: undefined,
     suicide: undefined,
     state: 'none',
     id: 1,
     process: 
      ChildProcess {
        domain: null,
        _events: [Object],
        _eventsCount: 5,
        _maxListeners: undefined,
        _closesNeeded: 2,
        _closesGot: 0,
        connected: true,
        signalCode: null,
        exitCode: null,
        killed: false,
        spawnfile: '/home/karl/.nvm/versions/node/v4.5.0/bin/node',
        _handle: [Object],
        spawnargs: [Object],
        pid: 7687,
        stdin: null,
        stdout: null,
        stderr: null,
        stdio: [Object],
        _channel: [Object],
        _handleQueue: null,
        send: [Function],
        _send: [Function],
        disconnect: [Function],
        _disconnect: [Function] } },
  '2': 
   Worker {
     domain: null,
     _events: { message: [Function] },
//...etc.

是否可以在这些类的属性之间创建一种关系，或者不可避免地将相同的信息保存在不同的类中？至于我进入文档，唯一的方法是再创建一个类，然后使用OneToOne关系，对吗？
