Hello everyone, I am trying to setup Mongrel to work with Apache on a VPS as part of a mephisto installation. Has anyone done this, and if so how did you edit your conf file to make it work? I used the info found on the mongrel site at: http://mongrel.rubyforge.org/docs/apache.html<http://mongrel.rubyforge.org/docs/apache.html> and one time I did get a mephisto splash screen, but it was

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 have a case where I am abstracting the creation of models. After a fair bit of indirection, I eventually get around to making a .new call. I need to be able to pass params to that .new call. I know I can''t use def initialize() in an AR model (rather frustrating). So, I have found some references to after_initialize, but that doesn''t work either. I see several threads on

hello to all I been working on this from past few days. .I am talking about separate migration for each one of the multiple database that a single rails application has connection with.I know that rails can work with multiple databases but what with migrations for e.g my main rails application has a connection to two databases 1> main_development 2> secondary_development Know suppose i

Hello there, I have some issues regarding xend domU migration to XCP VM. I try to migrate my old xend domU''s to my xen Could using the xva.py script. All seems to work quite ok, the migration process doesn''t throw any errors, i get a .xva file with a proper Size. When importing that file, immidiately the VG and LV is created, and VM properties are assigned correctly. But when

All, I have a quick question - is the purpose of implementing after_initialize to allow custom attribute initialization for AR descendants? I have been overriding initialize whenever I require custom setup of my model classes, like so: def initialize(attributes = nil) super self.Status = ''G'' end So I have a couple of questions: 1) Could I achieve the same

Hey Folks, after following the instructions for tweaking Typo to use rather ferret than DB queries to search article I got a strange NoMethod error when starting the console or the server scripts. /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb:1129:in `method_missing'':NoMethodError: undefined method `acts_as_ferret'' for Content:Class As you can

Hello, I am still reading Agile Web Developer pdf, it says about after_initialize and after_find. There is a Joe asks part when I read that they are special, however I didn''t really get the idea, why they are. On rubyonrails.org in the manual there is some sort description about their speciality, however their full descriptions are missing. What are the difference between

hi, i am having problems getting after_initialize for activerecord subclasses. basically, i am trying to use the guid plugin by andy singleton. i am having problems extending the class to the plugins i installed, so i figured i will just apply this to all the models in my project. i trled to add the following to my lib/ folder. my goal is to extended the activerecord class so that it uses

All, I''m wanting to initialize an ActiveRecord object. I understand that there is a method called after_initialize that appears to get called right after the ActiveRecord object is instantiated. Is after_initialize a Ruby thing or a Rails thing? Where is after_initialize documented? Can I pass parameters to it? If so, how? I want to initialize the "belongs_to" attribute of

Our Mephisto install kills Mongrels and causes Apache to pound the CPU. This started when we moved to Apache+mod_proxy_balancer+Mongrel. Here''s what we know: The following things are working OK, except when used in the combination listed above: mongrel, mongrel_rails, MySQL, Apache, mod_proxy_balancer. We believe these are all OK because we moved five other Rails apps to this

Hi all, Just had an interesting production failure while updating my Rails application - a bunch of code previously in config/environment.rb was put into config/initializers. That resulted in me having to wrap some code in config/environments/production.rb into an after_initialize do ... end block When backgroundrb was run against that code, the setup done in that after_initialize block

Hi, I''m using activemerchant and setting up a class variable using config.after_initialize. It works great for the first request, but then the variable is nil. config.after_initialize do ActiveMerchant::Billing::Base.mode = :test OrderTransaction.gateway = ActiveMerchant::Billing::PaypalGateway.new(...) end I''m assuming this is is due to the model reloading after each

Hey folks, I ran into a few people at RubyConf who were having 99% CPU issues. Please contact me if you meet the following criteria: 1. You are running a production site. 2. You are experiencing 99% CPU errors. 3. This is frequent enough that you cannot manage it. Thank you. Please contact me off-list about it. -- Zed A.

Let me apologize in advance as this is a topic that I feel passionate and opinionated about. If I''m coming on too strong, please forgive me. === Be opinionated=== My first piece of advice is simple: be opinionated. Change the method name to simply <feed_for>. Have it default to doing the right thing. Perhaps give an option to change the default feed format, but default to

I''m trying to add some per-object behaviors to objects descended from ActiveRecord, by using after_initialize() and instance_eval(), like this: def after_initialize self.instance_eval(File.read(''customers/default.rb'')) end (Ultimately the file path will be dynamic, this is just proof of concept.) default.rb just contains a few method definitions like this one: def

Hi I was recently taught about the useful ActiveRecord::Base#serialize. It''s very useful for persisting arbitrary objects through the regular database. For example, say you want to store a Set of all the years a Convention took place. You do: class Convention < ActiveRecord::Base serialize :years, Set end This effectively creates a Convention#years attribute, which is a set: you

Shouldn''t the second spec fail? I''m trying to provide a default value in the model (I''m well aware this is normally the job of the controller, but it seems right to be the model in this case). Also, after_initialize doesn''t seem to be the right way of doing this, but before_create or any of the other things don''t make the first test pass. specify

I have a need for a scheduler to run from inside of my rails application. I am familiar with Java (J2EE) and new to Ruby. In Java I would have used a framework called Quartz. I would have created a servlet and in the init method started up the Quartz framework. I have created a new Ruby class and called it StartCron.rb in the Components folder of my Rails app. I have been playing with the
