# myproject/apps/core/middleware.pyfrom threading import local_thread_locals = local()def get_current_request():    """    :returns the HttpRequest object for this thread    """    return getattr(_thread_locals, "request", None)def get_current_user():    """    :returns the current user if it exists or None otherwise """    request = get_current_request()    if request:        return getattr(request, "user", None)class ThreadLocalMiddleware(object):    """    Middleware to add the HttpRequest to thread local storage    """
