New plugin: Flagger

Hi all,

I’ve just put out a plugin for ActiveRecord that stops you having to
write repetitive bundles of methods such as

class Order < ActiveRecord::Base
def self.paid

def self.unpaid

def mark_as_paid
  update_attribute(:paid, true)
  # related tasks

def mark_as_unpaid
  update_attribute(:paid, false)
  # related tasks


It gives you dynamic attribute-based methods similar to these. You can
use certain negative prefixes to look for false values - Order.unpaid
returns orders where paid is false - and chain attributes together, as
in Order.paid_and_delivered, Cocktail.shaken_but_not_stirred, etc.
More info here:

I’d really appreciate a few people kicking its tyres in anything other
than MySQL, or in Rails versions 1.0.x (is anyone still using those).
Comments/bugs/test reports are always welcome.
