May I suggest ?
class Unauthorized(Exception): pass
def check_permission(permission):
if not DB.check_permission(permission):
raise Unauthorized(permission)
def requires_perm(func):
def with_check(*args, **kw):
check_permission(func.__name__)
return func(*args, **kw)
return with_check
@requires_perm
def my_method():
# do something useful here
