similar to: Custom Active Record Callbacks?

I was just wondering what about a report that I made almost 2 months ago: Active Record observers broken<https://rails.lighthouseapp.com/projects/8994/tickets/4087-activerecord-observers-cant-be-used-for-before-callbacks> I think it''s a pretty big bug. In Rails 3, creating an observer with a "before_save" callback (for instance) will result in all observed models being

When I am using my rails models in my worker class, it appears the background worker class is always using development no matter what I do. I set background.yml to production. I even have ENV[''RAILS_ENV''] ||= ''production uncommented in environment.rb. I don''t have the development db even created on my production box, so not sure where it is getting development

I am having an issue of deciding where I should put the business code for example the more complex code coming off the controller. Right now, I am just thinking to put it in the ''lib'' directory and the do something along these lines: require_dependency "system_process" class SystemMessageController < ApplicationController include SystemProcess ... ... Where

I''m working on a small project with a friend, and one of the things we needed to do was send off an email whenever someone signs up an account. His implementation was pretty simple - throw a deliver_welcome call inside the controller after the signup. I''m sure that this is a pretty common thing to do. The problem, in my mind, was that the app now became tied to two places -

Inspired by but not completely related to: https://bugzilla.redhat.com/show_bug.cgi?id=664558 "RFE: Allow to set log callback in Ruby bindings" How can we make callbacks useful? First off what are we talking about? There are several callbacks that can be registered through the C API: (a) error callback http://libguestfs.org/guestfs.3.html#guestfs_set_error_handler (b) out

Just wondering how to best integrate with pagination and still stick to MVC... Say I have a Post model that has a published attribute. I want to show all the recent published posts on a page. My first instinct is to create a method in the Post model called recent that does the find with proper conditions and order, but the problem I have is how do I use that with pagination (which definitely

* I committed into CVS the gendb patch that I sent to the mailing list on September 12. Arnaud, I hope you approve of this patch; it is more reliable than the previous method in tracking the correct dependencies. * This, together with some other minor recent changes on the Development branch, is between the "before_PSE_3" and "after_PSE_3" tags. Arnaud: if you

virtio allows drivers to suppress callbacks (ie. interrupts) for efficiency (no locking, it's just an optimization). There's a similar mechanism for the host to suppress notifications coming from the guest: in that case, we ignore the suppression if the ring is completely full. It turns out that life is simpler if the host similarly ignores callback suppression when the ring is

I''m using the following RJS template to spit out a div containing a list of projects: page.replace_html ''results'', ''<div>'' @projects.each do |p| page.insert_html :bottom, ''results'', p.name + "<br/>" end page.insert_html :bottom, ''searchresults'', ''</div>'' page.show

Hello, Usually is it easy to identify a valid non-subscriber-posting. Example given: the four postings about "bugzilla is back" in last day. Today there is a posting from the data plane development kit project, http://dpdk.org/ DPDK is a set of libraries and drivers for fast packet processing. Packets being network packets. That posting is not spam, but it should not go to this

Hello all, Is there a way to register callback that runs before/after passes? PassTimingInfo seems to do a similar thing by calling PassInstrumentationCallbacks::registerBeforePassCallback / registerAfterPassCallback, but it is hard-wired with StandardInstrumentations class. Do we have something similar to RegisterStandardPasses, so custom callbacks can be added from somewhere outside LLVM?

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)
