Rails - Jun 2006 - Default value plugin

I''m releasing a very small plugin that allows you to specify default  
values for fields in models. Ordinarily, you might do this in your  
schema, I guess, but then it''s awkward if you need that on a  
serialized field or need your default values calculated somehow.

So you can do something like this: (repeated from an earlier post and  
the README)

   class Mixture < ActiveRecord::Base
     serialize :color
     default_value :color, [255, 0, 0]
   end

   m = Mixture.new
   m.color # => [255,0,0]

Here''s the README:

   http://mdaines.com/svn/plugins/default_value/trunk/README

To install: (as usual)

   script/plugin install http://mdaines.com/svn/plugins/default_value/ 
trunk


Thoughts, comments?

I think that''s actually pretty neat. I can think of a few uses for that
already.
