Hi Chris,
Isn't the "self" parameter in your newaction function definition an
error? I believe the correct syntax is --
$ ipython
In [1]: def factory(param):
...: def deco(func):
...: def newaction(*args, **kw):
...: print 'do sth. with %s' % param
...: return func(*args, **kw)
...: return newaction
...: return deco
...:
In [2]: class controller:
...: def __init__(self):
...: pass
...: @factory('param1')
...: def action(self):
...: print 'interesting stuff'
...:
In [3]: contrl = controller()
In [4]: contrl.action()
do sth. with param1
interesting stuff
