尝试扩展AbstractUser以在Django中创建多个用户类型

So I have been searching all around the internet for a full example of how to user AbstractUser when u have at least 2 different models. Didn't find anything conclusive.. at least that would work on latest version of Django (2.0.1). I have 2 models, teacher and student, and registration needs to be different.

Did I start good ? What is the right approach ? So I have been searching all around the interne
