For use in your models. Accepts one or more date columns as arguments and makes a method for each that allows the checking of whether or not the date is nil. Got the idea from Jamis Buck here: http://weblog.jamisbuck.org/2005/12/14/two-tips-for-working-with-databases-in-rails

class Action < ActiveRecord::Base
	acts_as_toggled_date :completed_at
end

...is the same as...

class Action < ActiveRecord::Base
	def completed?
		!completed_at.blank?
	end
	
	def	completed
		self.update_attribute(:completed_at, Time.now.utc)
	end
	
	def	uncompleted
		self.update_attribute(:completed_at, '')
	end
end

...which means you can...

@action = Action.new
@action.completed? ? "Completed" : "Git 'r dun"

...or...

It works best with dates named like completed_at, published_at, etc.
