#
# Use this in models for status codes etc.  Will dynamically create a class constant
# for each row in the table. The name of the constant will be based on the field specified.
# Typically it would be code, though name might be useful in some cases.
#
# This will build the constants once on rails startup. It only hits the database once, the find(:all),
# so should be reasonably efficient as long as it's used for small tables only.
#
# Put this in lib/create_id_constants.rb

# There are two modules, one for instance methods and one for class methods
# Use 'include' and 'extend' separately
