Question

I’m newcomer in django, and here is question:

I have model class:

def Client(models.User) # django.contrib.auth.User
   company_name=models.CharField()

How could I get Client object when I have user object (and user is client)? One way is to filter objects by username:

user=request.user
client=Client.objects.filter(username=user.username)

But I think there is some different and more beautiful method to do this in django, because user is client (they are related one-to-one in database), is one there?

From the documentation on inheritance:

If you have a User that is also a Client, you can get from the User object to the Client object by using the lower-case version of the model name:

my_user = User.objects.get(username = 'foobar')
client = my_user.client

If the User instance is not a Client, you’ll get a Client.DoesNotExist exception.
