I have a Topic that has_many comments. In the search results only want Topics to show up, but I want them to include the text of the comments that they have when they are indexed. To do this I''ve added a :comments_text field for acts_as_ferret and the comments_text method gathers the text from all comments up into a string that can be indexed. The trick is that when comments are added,

Hi, I have a model class like so: class Candidate < ActiveRecord::Base validates_presence_of :name @@index = FerretConfig::INDEX def self.after_destroy puts "Ferret: after_destroy called" @@index.query_delete("+id:#{self.id} +ferret_class:#{self.class.name}") optimize_index end end But when I delete a record, the after_destroy is never called.

Hi, I am trying to replace my old database trigger with ActiveRecord callbacks in rails. I have a model like following: class Action < ActiveRecord::Base belongs_to :inquiry def after_update #clean up all action associated with the inquiry. Action.update_all("latest = ''''", ["inquiry_id = ?", self.inquiry_id]) #find the latest action

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: class

I''m not sure how to implement this so I''ll describe what I currently have done then what I wish to have happen currently, I have a generic observer for several models class AuditObserver < ActiveRecord::Observer observe Foo, Bar def after_update(model) model.log("UPDATED " + Time.now.strftime("%m-%d-%Y %H:%M")) end def after_create(model)

Hey guys, I''m having a hard time w/ the after_update callback on rails... As far as I can tell, when I define a after_update callback on a model, the attributes of the object have the same values that they had *before* Base.save was called. I''m probably wrong so here''s the code: UNIT TEST: def test_register_item_adjusts_account_balance account =

I have this situation where in an after_update, I would like to know the previous value of the record instead of simply being notified the record has been updated. For example let''s say I had a table called ''foo'' which had a field ''new_flag''. I want to know when the ''new_flag'' field changes from 0 -- > 1 in an after_update so I

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 line #5 of app/views/item/view.rhtml: 5: <H1

I''ve read in rails api that there is a touch parameter and I want to use it in my application. I have something like that class User < ActiveRecord::Base has_many :phones after_update :updated def updated ... end end class Phone < ActiveRecord::Base belongs_to :user, :touch => true end I want that every change of any phone number would change User updated_at

I''ve enabled page caching on a site I''m currently constructing. The sweeper is called upon any changes made to the model, as expected. The sweeper code is as follows: class PersonSweeper < ActionController::Caching::Sweeper observe Person def after_update(person) expire_staff_page end def after_destroy(person) expire_staff_page end def

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

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

hello everybody. i need to log "who did what" on some models. i was reading recipe 59 of rails recipes and i created something like that: class LogSweeper < ActionController::Caching::Sweeper observe :model1, :model2, :model3, :model4, :model5, ... after_save(model) save_log(model, "save") end after_destroy(model) save_log(model, "destroy) end

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

Help please. I''m trying to observe a User class, but I can''t get this to work, the after_create method never gets called... (the breakpoint never gets called) app/models/user_observer.rb: class UserObserver < ActiveRecord::Observer def after_create(user) breakpoint setting =

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

Hi, I''ve started to implement page caches but I''ve hit a brick wall getting a sweeper to clear the cache when needed. It seems that any models that I tell it to observe aren''t being observed properly. If I add the sweeper to a controller the initialize method runs, but no matter what I do the after_save/after_update callbacks aren''t running. Also if I try to
