Hi cootetom,
For decorators you must have a look at the excellent articles/tutorials:
http://www.artima.com/weblogs/viewpost.jsp?thread=240808
http://www.artima.com/weblogs/viewpost.jsp?thread=240845
It covers decorators with (what you want to do) and without parameters.
Regards
Chris

Subject: Python Decorators
Hi all, not exactly a django question but here goes... I'm trying to
implement a decorator with one positional argument and one keyword
argument. My wrapper function gets the positional argument just fine
but the keyword argument throws an error "NameError: name 'as_string'
is not defined."
Code is;
def widget(widget_switch, as_string=False):
def decorator(func):
def wrapper(*args, **kwargs):
# logic in here can access the value of 'widget_switch'
but 'as_string' is not defined?
return func(*args, **kwargs)
return wrapper
return decorator
So if I decorate a view function with "@widget('some_widget',
as_string=True)" then the wrapper function is unable to use
'as_string'. I thought this was how python closer worked?
Any ideas?
