Here's a question:

I have the exact same validation code in 2 different models.

OK, you're thinking, combine the models.  Not in this case.

So, in Rails, is there a way to reference the same validation for 2
different models?

E.g.

  validate :foo

  def foo
    bar
  end

Appears in /models/a.rb and /models/b.rb

Can I make foo DRY?

TIA,
Craig
