similar to: after_save deletes is an exception is raised?

I have a very strange problem here. I do not get this. So any help is greatly appreciated. Basically I have a model that calls a method in the background process in the "after_save" method. Let''s call the model products. So what happens is this: 1. I create a new product. 2. Everything works and the product is saved with id 13. 3. A method is called in my background

Is there a way to determine if attributes were changed? Let''s say in the before_save or after_save method? Thanks for your help.

I have a simple question. Let''s say I do this in one of my models: after_save drb_conn.some_method(self) end When that object gets over to the background process is it the exact same as?.... Model.find some_id #in the background process As far as my background process is concerned passing the object is not any different than passing the id and using the find method? Because

I have a pretty strange problem. Here is basically what I have to demonstrate my problem: class Event < ActiveRecord::Base def after_create AnotherClass.find_event(id) end end class AnotherClass < ActiveRecord::Base def self.find_event(event_id) e = Event.find event_id end end Here is the catch 22 and it''s quite annoying. Basically ActiveRecord puts to whole save

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.

I need to know what controller and action the user is currently in to do various things in my layouts/application.rhtml file. Isn''t there is a better way than: <% if params[:controller] == "whatever" && params[:action] == "whatever" %>some html<% end %> I know in the controllers you can just use controller_name, but that is not provided

I''m trying to add some code for my ActiveRecord class so that it is executed whenever an object is updated, this code is a seperate process that reads from the same table represented by my model class so when it runs it needs the database to be up to date. In the following situation this is fine: # MyModel def after_save `/usr/local/bin/update_models -i #{self.id}` end # controller

If there is an exception raised in my worker I rescue it and throw it into the log. This is decent, but it would really help to find out more information. Like the line number, the stack trace, etc. Is this possible? Thanks for your help.

I am pretty confident that mailers do not work in backgroundrb. Can anyone confirm this? Because when I try to do Notifier.deliver_some_method I get an error saying it cant find the templates for my email. The funny thing is that when I run script/ runner Notifier.deliver_some_method it works just fine. Any ideas? Thank You, Ben Johnson E: bjohnson at contuitive.com O: 800-341-6826 M:

I made a worker that run an infinite loop and does the following: while true @logger << "logging #{Time.now}" sleep 2 end In my secong console I did: tail log/backgroundrb.log -f This is so I could see the line getting added to the log every 2 seconds. Then in my other console I started script/console and created a new worker. Then killed it with

I have a simple question, but can''t seem to figure this out. I added an in place editor field and didn''t like how it didn''t use the save method. It uses the update_attribute method which does not run validation, etc. So I just added the method in my controller myself: def set_event_url begin @event = Event.find params[:id] @event.url =

class User < AR end user = User.new Let''s say that I have a user instance with me. After this record is saved I want an after_save callback which would print the id of the record. The only catch is that I am not allowed to change the User class. How can I accomplish my goal? Is that even possible to add an after_save callback on a particular instance object. Any metaprogramming

Since MiddleMan is an uninitialized constant in a worker how do you create new workers inside a worker?

Let''s say I wanted to find 3 products from my database and put them in the layouts/application.rhtml view. Where do I find these 3 products? Do I just do it in application.rhtml? <% for product in Product.find(:all, :limit => 3) %> Because I was under the impression that you really don''t want to do this in your views. You should do this in your controllers and

Hi all, I''m running into a brick wall trying to figure out my problem here. I have a model that has a boolean property called "paid". I''d like to add the following to my model: def after_save self.amount == self.splits.sum(:amount) ? self.update_attribute (:paid, true) : self.update_attribute(:paid, false) end The problem is, when I do this I get an error that

I have a Production model, which represents a farmer''s crop. After create (via after_save) I call a method that creates one or more Supply models, which represent a week of anticipated product harvest. After each of those are created, a class method gets called that tries to match each new Supply with outstanding orders for the same time period. If a match is made, a transaction (an

How do you tell if an foreign key attribute has been changed? For example, lets say you have a model with attribute table_a_id. Would you do this? def table_a_id=(value) if value != table_a_id @table_a_changed = true write_attribute ''table_a_id'', value end end def table_a=(value) if value != table_a @table_a_changed = true
