...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 people trying to use after_initialize, but no conclusive answers to the same errors I am seeing -- undefined method `stringify_keys! Example refc: http://www.ruby-forum.com/topic/86173 My after_initialize is just this simple code:...

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 a...

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 req...

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 wasn''t run, leading to a failure in several background jobs that required it. Two purposes for the email - firstly, a heads-up that this is a problem, in case anyone else ends up b...

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 my new ActiveRecord obj...

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 b...

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 e...

Hi everybody I would like a function as the "before_save" method in the model. But it must be the opposite. When I take out data from the database through the model, I want to call a function before the data are available in the controller. Can anyone help me? ---- >>>> thx <<<< ---- -- Posted via http://www.ruby-forum.com/.

I''m trying to use redis-store as my cache_store. I also have an app_confirg.rb initalizer which loads a yaml file for config settings. In my redis.rb initializer I have: MyApp::Application.config.cache_store = :redis_store, APP_CONFIG[''redis''] However, this doesn''t appear to work. If I do Rails.cache in my rails console I can clearly see it''s using

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 support_phone_num...

Hi everyone, I am trying to extend an active record model using obj.extend(module). The aim is to overwrite some of the model methods depending on what''s in the object. For example, the base class would be "file", with objects such as "image", and "text". The aim is to be able to something like this: file = File.new() file.extend(Image) file.process

In Rails 3, is it possible to have a plugin inside an engine? Adding the lib dir of the plugin to autoload_paths doesn''t seem to work. I can manage to load it by adding that path to $: and requiring the init.rb file, but I''m not sure that''s the correct approach.

...looking for a way to pass environment variables to my Rails app via Mongrel. I want to conditionally execute code in environment.rb based on these environment variables. Background: 1. I have some special stuff I want to do when my Rails app first starts 2. So, stuff it in environment.rb in after_initialize, right? 3. Not this time. I have several other background processes that include environment.rb, but shouldn''t run this code. Some other background: I''m using lighttpd, mongrel, and mongrel_cluster If there''s not a way to do this, I can fallback on having all the...

Just starting a new thread so that it''s easy to follow. I just submitted a patch at trac to add a new class method called "set_default_values" ( not a great name I think ), which lets you do all kinds of crazy stuff with setting default values. This ticket is at http://dev.rubyonrails.org/ticket/9093 and example pastie is at http://pastie.caboo.se/81925 It also lets you make

Nothing special, just my first plugin. it came out of a request I saw on the list from someone who wanted to be able to tell if a model''s attributes had changed prior to being saved. Well, this plugin does just that (at least I hope it does). http://rubyforge.org/projects/actsasmodified/ Please see the README for details. Constructive comments and criticisms are appreciated.

...bjects of Person to do so, and the third creates a new table, "cars", and modifies the "persons" table to create a :has_one relationship of Person[1]->[1]Car. Let''s also say I want all Persons to have at least one car, so I change my Person model to have: def after_initialize self.car = Car.new unless self.car end Now, what happens, is that when I issue a "rake migrate" on my intial database When I start from scratch (new database) and do a rake migrate, my data load fails because it uses the model class Person, yet Person''s code now has an a...
