similar to: question about observer callbacks

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

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 can''t seem to get a model observer to work. In my environment.rb I have: config.active_record.observers = :item_observer In item_observer.rb I have: class ItemObserver < ActiveRecord::Observer observe Item def after_update(item) if @old.active != item.active logger.debug ''observer#after_update'' #... end @old = nil end def

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 =

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 All, Having problem setting up an observer to log changes to a database. I have following the Prag Rails book but think I have something missing. I am trying a simple puts to see if the observer is working, but getting nothing on the console. Here is what I have. I don''t get any errors. Thanks for any suggestions/references to debugging. Dave The two models: display_ad.rd

eh, like so? def after_create(model) generate_hotel_param_files(model.id) generate_hotel_setup_files(model.id) end def after_update(model) generate_hotel_param_files(model.id) generate_hotel_setup_files(model.id) end On Jul 21, 9:59 am, David Nguyen <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote: > Hi, > I have to make an observer if a

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

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 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 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.

Hello, I''m running Mongrel 0.3.13.3, cluster 0.2.0, and Rails 1.1.6 and I have a problem with a sweeper not having access to the controller instance.

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

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 try to understand the following issue : - when creating a new User record, I use an UserObserver to trap the before_save call back and send an email def after_create(user) UserNotifier.deliver_signup_notification(user) end - Once created a user can ask for a password reset, which is also trapped by the UserOberver def after_save(user) UserNotifier.deliver_reset_password(user) if

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 =

Hello, I am exploring the "Testing" part of Rails, but It seems some things work differently than I thought it would. Consider the following model: class Client < ActiveRecord::Base has_one :project def after_create Project.new(:name => self.name, :is_client => true, :client_id => self.id).save end def after_update

For example - i have a sweeper for one model(in this case About). class AboutSweeper < ActionController::Caching::Sweeper observe About def after_create(data) expire_about(data) end def after_save(data) expire_about(data) end def after_destroy(data) expire_about(data) end def expire_about(data) FileUtils.rm_rf
