在Django中扩展现有的User模型

Let's say I have an app that has 3 kinds of user

假设我有一个有3种用户的应用程序

Employee with fields like work_number, department etc.
员工有work_number，department等字段。
Member with fields like phone_number, .....
会员拥有phone_number，.....等字段
Agent with fields like company_name,.....
具有company_name，.....等字段的代理

They're different.

他们是不同的。

I write models like this:

我写这样的模型：

class Employee(models.Model):
    user = models.OneToOneField(User)
    department = models.CharField(max_length=100)
    .......

class Member(models.Model):
    user = models.OneToOneField(User)
    .......

class Agent(models.Model):
    user = models.OneToOneField(User)
    .......

Now I can :

现在我能：

u = User.objects.get(username='xxxx')
u.employee // it works...

but, ONE user has THREE profiles (employee,member,agent) !!!

但是，一个用户有三个配置文件（员工，会员，代理商）！

It's not matches my business, the business role is ONE user could be and must be only one kind of 3 profiles.

它与我的业务不匹配，业务角色是一个用户可能并且必须只是一种3个配置文件。

What's the best way to solve this?

解决这个问题的最佳方法是什么？

#1

Why not have a single profile with a role associated (even if certain fields will never be filled for a specific role)?

为什么不将一个具有关联角色的配置文件（即使特定角色永远不会填充某些字段）？

You can handle the validation through forms and instead having 3 different models you would have 3 different forms.

您可以通过表单处理验证，而不是有3种不同的模型，您将有3种不同的形式。
