Plugin - How to access object from instance method
Quick question: Given a basic plugin... how can I access an object that
I instantiated in the acts_as method from an instance method? Probably
some sort of accessor... but where?
def self.included(base)
base.extend ClassMethods
end
module ClassMethods
def acts_as_test
object = Object.new ## This object needs to be accessible from the
Instance Methods
end

after_(read|find) callback?
I am pondering the possibility of encrypting/decrypting some fields
in a SQLite backend on-the-fly.
The point of the message is not security, I know that''s broken, but
whether there''s a technique that provides on-the-fly save/read
filters. Of course the solution would need to work transparently in
joins, so
user.posts.last.title
would do the right thing if title

"include" versus "extend" - what's the difference
Hi,
Just wondering when one would use "include" over "extend"? Both seem to
bring in methods to the class no?
The context is I''m just trying to understand why both are used with the
acts_as_audited plugin:

before before_validation callback
Hi,
I was looking around a bit and couldn''t find any callbacks that
executed before before_validation
The current problem with using before_validation is that it won''t fire
if I''m not using validations with #save(:validate => false) - which
makes sense. Before_save won''t suffice because I want these callbacks
to fire before validation on the occasions that

Setting a callback whose action depends on the previous state of the object
I''ve been reading about ActiveRecord::Callbacks and they''re really
cool. But I have a complex need I''m not sure they answer.
Let''s say we have a User model. User has a #status attribute, which
can be either "active", "closed" or "blocked".
I want to set a callback to perform an action if an "active" User has

Sometime ago I ran across a webpage where someone had identified the
full callback sequence for an object lifecycle including AASM with
it''s :enter and :exit and whatnot callbacks. Unfortunately, I can''t
find it and searches don''t seem to help.
Does anyone have a reference to a page that shows the callback
sequence with Acts As State Machine (the gem)?

#logger.info self.class.to_s
new_copy = self.class.new( @copyable_attributes )
the logger spits out "Datatype", but I get an error from rails saying:

Seek brilliant Rails programmer to add one field to acts_as_taggable
I''m on the downhill side of a large project that requires an

class MyCallback
def initialize(attr_names)
@attr_names = attr_names
end
def before_save(model)
@attr_names.each do |attr_name|
