Rails - Mar 2007 - convert to method call?

Hi all,

I would like to store a method call in a database, yet once saved I
don''t know how to convert it from a string back to a method call.

example:

distance_of_time_in_words(order.created_at, order.created_at +
order.due_date)

The value of order.due_date "10.weeks", but could be
"20.days",
"100.months", etc.

Just wondering if there''s a way to convert a
     string "10.weeks"
        to a method
     10.weeks
     ?

Thanks for your help!

Dave

found it. "the google" said:

I split the 10 and weeks into two separate columns, due_in and due_from 
(couldn''t thing of what to call em).

This seems to work just fine.

order.due_in.send(order.due_from.to_sym)
