How to set up Django models with two types of users with very different attributes

Question

Note: I\'ve since asked this question again given the updates to Django\'s user model since version 1.5.

I hope I understood your problem... maybe this can work? You create a abstract CommonInfo class that is inherited in into the different Sub-classes (student and businesses)

class CommonUser(models.Model):      
    user = models.OneToOne(User)
    

    class Meta:
        abstract = True


class Student(CommonUser):
    

class Business(CommonUser):
    

In this case the models will be created in the DB with the base class fields in each table. Thus when you are working with Students you run a

students = Students.objects.get.all() 

to get all your students including the common information.

Then for each student you do:

for student in students:
    print student.user.username

The same goes for Business objects.

To get the student using a user:

student = Student.objects.get(user=id)

The username will be unique thus when creating a new Student or Business it will raise an exception if an existing username is being saved.
