Ones and Threes

I’ve discovered Luke Redpaths ActiveSpec gem, and it looks great, particularly for validating objects conditionally based on state. Example:

class User
  must_satisfy :valid_user_specification
  must_satisfy :activated_user_specification,
    :if => :activated?
end

That’s a lot neater than lots of conditionals scattered through validation statements. And funnily enough, this precise scenario (users validating differently depending on activation) is something I was working on two weeks ago.
