I believe python decorators are just syntactic sugar.

I have a rather complex decorator written by someone else. What I want to do is call a decorated version of the function one time based on a descision or call the original function (not decorated) another time. Is this possible?

The @ syntax is totally optional.
With:
decorator(original_function)()
Without:
original_function()
A decorator is just a function which takes a function as an argument and returns another one.

I have a 'name' attribute on a Person model
and every time I access the name attribute, I want name.capitalize to be returned.
Doing the following inside the model won't work,
def name name.capitalize end
so what is the alternative?
Answer Snippets (Read the full thread at stackoverflow):
Class Person def formatted_name name.capitalize end end

Try this:
def name self[:name].capitalize end
I suggest you to create a secondary method with your custom formatters .
