Row Version Migrations

The more I use Rails, the more plugins I seem to create. Each time I start a new project, almost the first thing I find I want to do is to copy a chunk of code from an existing project. The moment that happens, I think: Plugin!

So here it is. A plugin that automatically generates the following row version columns for every table:

:created_at,   :datetime,  :null => false

Not so difficult. In fact it seems almost trivial (as usual) but it means all my tables now get date/time stamps and optimistic locking for free.

Enjoy. As always, feedback, suggestions, patches, criticism, all welcome.
