The first argument of an instance method is self, so the wrapper function should be defined with self as the first argument, and pass it to the wrapped method when calling it:

def my_decorator(view_func):
    def wrapper(self, request, *args, **kwargs):
        print('-start-')
        print(request.data)
        print(args)
        print(kwargs)
        print('-now-')
        response = view_func(self, request, *args, **kwargs)
        return response
    return wrapper

At the request of your comment, here is how you can parameterize the decorator with an additional argument extra_arg:

def my_decorator(extra_arg):
    def decorator(view_func):
        def wrapper(self, request, *args, **kwargs):
            print('-start-')
            print(request.data)
            print(args)
            print(kwargs)
            print(extra_arg)
            print('-now-')
            response = view_func(self, request, *args, **kwargs)
            return response
        return wrapper
    return decorator
