similar to: after_update and increment!

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

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''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. NoMethodError (undefined method `session'' for nil:NilClass): /app/models/audit_sweeper.rb:16:in `log'' /app/models/audit_sweeper.rb:9:in `after_update''

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

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 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,

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. -- Posted via

Hi, AFAIK after_create is called after_save if the entry does not exist in the DB. Is there a way to tell if a specific model is new or not in after_save? I have to do something like: def after_save add_to_history ''save'' end def after_create add_to_history ''create'' end However after_save is called when creating too. -- cheers, M.

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 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

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''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, Why is cache_sweeper not a documented method? I was pretty sure it used to be, but I could be wrong. I can''t seem to find any information on it anymore in the online docs. As a side note, looking at the code for cache_sweeper it appears to only work with the :only option, not :except (ignores it)... what''s the reason for this? Thanks, Andrew

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

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 =

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 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

With after triggers in Postgres, there are special NEW and OLD vars accessible to trigger functions. Any such thing in Rails? Or would it entail doing something like setting a class var in before_update? Jack -- Posted via http://www.ruby-forum.com/.

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

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
