Given this code you will be granted the following abilities:
status
=> returns a string '' with marks according to what status is set
status=('')
=> enforces the status set to match the status string passed in
archived?, on_hold?, featured?
=> check on status of flag
archived!, on_hold!, featured!
=> turn on status & save
not_archived!, not_on_hold!, not_featured!
=> turn off status & save
scopes :
not_archived, not_on_hold, not_featured,
archived , on_hold ' featured
--
please note : you can protect your code from failing to exectue when your migrations
have not run yet (like on staging) but the code referencies fields about to be added
via a migration - by the use of a block
In the above example the block contains a reference to 'not_on_hold' - this is a scope
which is created by the argument to acts_as_status. :on_hold must exist in the database
for this block to run - and actually - if anyone of the status marks _at database attribute
doens't exist - the code will not install itself properly
