Description

In django.utils.decorators.decorator_from_middleware(), the portion which calls the middleware's process_view() method does with the dynamic argument modifies * and **, even though the middleware protocol specifies that the args and kwargs values should come in as separate distinct arguments.

If this function is used to transform any middleware that implements the process_view() method into a decorator, a TypeError is raised when any view using that decorator is executed.

TypeError: process_view() got an unexpected keyword argument '...'
