Same result for pk=request.user and pk=request.user.id in django

Question

class MyUser(User):
    job = ...
    city = ....

MyUser.objects.get(pk=request.user) and MyUser.objects.get(pk=request.user.id) give me the same result. From doc, pk must be an int. But request.user is an object. Why queries are the same for object and user id?

edit : I know that request.user is object but I want to know why results are same.

Thanks in advance

This is by design - if you pass a model object as the parameter to a query, it is the same as passing its primary key.

If this wasn't the behaviour, either passing the pk would be required, or an error, which would merely be annoying.
