I''m not sure how to implement this so I''ll describe what I currently have
done then what I wish to have happen

def after_update(model)
model.log("UPDATED " + Time.now.strftime("%m-%d-%Y %H:%M"))
end

Search result inconsistencies due to indexing
I seem to be having problems with getting my searcher to be consistent
while indexing. I am running the latest version of ferret (0.10.13) and
I am using the Searchable plugin. Currently the way it indexes is by
using a callback in the model of either after_update or after_create to
index the fields that I have setup to be indexed.
Right now I update the index about once every 4 or 5

cache_sweeper causes undefined method error
I created a sweeper ItemSweeper and saved it in
app/models/item_sweeper.rb. Then I put this in my item_controller.rb:
cache_sweeper :item_sweeper, :only => [:create, :destroy, :update]
But now when I call the view action, I get this error:
ActionView::TemplateError (undefined method `title'' for nil:NilClass) on

Observer behavior differences between DEV and TEST environments ?
Hi all !
I''m having an issue and I can''t seem to make heads or tails of it.
I am attempting to add an observer to a model object. I created
app/models/greenback_transaction_observer.rb, inherited from
AR::Observer, defined methods, registered in config/environment.rb,
but things don''t work...
So, I took a step back and put in the following code:

DRb server crashing
I''m having a problem where the DRb server seems to be disappearing
(crashing?) and I don''t know how to track down the cause or work around
the problem.
Unfortunately I haven''t found a way to reproduce the problem, but it
seems to happen fairly often (maybe once a day). Other then that ferret
seems to be working well.
I can''t seem to find any trace of the

Bye Bye, Observers
Observers will be no more as of Rails 4, farewell, never been much of a
fan. However, I''m using it in one of my gems which enables model attributes
for use with a WYSIWYM editor. The resulting markup is persisted, but in
order to use it in a view, it has to be nokogiried in a helper which
fragment caches the result. This cache has to be zapped once the model
instance is either

Possibly same issue as ''duplicate search results'' topic?
Unfortunately I''m a newbie to ruby, rails, and acts_as_ferret. Also,
I''m working in code I mostly didn''t write, so I''m kind of unsure of
things. So this may be a dumb question. It also may be the same issue
as the topic ''Duplicate search results'', but I''m not sure.

Specify callbacks before associations
In the RoR API documentation
(http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html) for
callbacks, there is a note that says:
"*IMPORTANT:* In order for inheritance to work for the callback queues,
you must specify the callbacks before specifying the associations.
Otherwise, you might trigger the loading of a child before the parent
has registered the callbacks and they won?t

save without after_save, after_create, after_update?
How to update attribute(s) and save a record instance without triggering
the hooks: after_save, after_create, after_update?
I know it''s possible with Record.update() but this is dynamic. Only
receive the instance, without knowing its class (thus cannot call the
class method update()). Or is there a way of knowing the class and
calling the class method?
Thank you.

LoginSystem : make @session available to models
Hello.
LoginSystem is cool, it populates the @session instance variable of
controllers with many useful info.
The fact is : it would be cool to let models know about the session,
too.
For instance, after_update and after_create callbacks could store *who*
did *what* on *what.
Aim : having ActiveRecord::Base::session defined, returning the @session
of the controller which manipulates the

after_update and increment!
I''ve got a strange behaviour that didn''t seem to be happening before I
upgraded to 1.2.
I''ve got two models - questions and results.
When a user answers a question, his answer is recorded in results. In
my results model, I have an after_create that increments! a count in
the question model.
This increment is now triggering an after_update method I have in a

ANN: acts_as_ferret
Hi all
This week I have worked with Rails and Ferret to test Ferrets (and Lucenes)
capabilities. I decided to make a mixin for ActiveRecord as it seemed the
simplest possible solution and I ended up making this into a plugin.
For more info on Ferret see:
http://ferret.davebalmain.com/trac/
The plugin is functional but could easily be refined. Anyway I want to share it
with you. Regard it as a

Problems with validates_lenght_of
I''m building a login system, and I want users to be able to update their
password, first name and last name after signing up. So, when signing up
password can''t be nil, and it must be between 6..20 characters long. However,
on update, the user can choose to leave the password field empty (but fill in
other stuff, like first name) and then I want the User model to not update

making acts_as_ferret thread safe?

I get a synchronize error (see below) when I run a lib script with

Automatically Indexing Associated Models
PROBLEM
I have two models, Blog and BlogComment. When a blog is initially
created, it has no comments. Upon creation, the title and body are
automatically added to the ferret index and directly searchable.
However, when a comment is added to a blog, that comment does not get
added to the index and is therefore not ferretable. The desired behavior
is that when a comment is added to a blog, that the
