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.
