how to let django return response to web browser at my own function

[肖子聪]

I want to write a function 'get_user_or_log_in' to check whether the user has logged or not. If logged, return user's name, if not, redirect to the login page. I want to use it like function 'get_object_or_404'. But I do not know how to let django response at my own function not just at the end of functions in views.py .

You probably just want to use the login_required decorator.
