I’m wondering if it’s possible to pass an argument to a custom finder  
method when working with cache\_fu. The excellent “Advanced Rails  
Recipes” book has the following example:

The custom finder method in the model wasn’t changed? That’s right!  
The cache\_fu plugin offers a number of really sweet features, and one of  
our favorites is being able to pass a method name to the cached method  
and have the result cached. For example, now over in our controller we  
can use User.cached(:find\_latest):

@users = User.cached(:find\_latest)

How can I do it so that find\_latest actually has an argument like

def self.find\_latest(geography)

and then do

@users = User.cached(:find\_latest(‘North America’))

Thanks.
