similar to: Purpose of after_initialize in ActiveRecord?

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

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

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

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 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

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

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

I''m having a strange problem with webrick spinning forever. I have a view ''list'' that renders a collection: <%= render :partial => ''item'', :collection => @items %> The item partial looks like so: <div id="item_<%= item.id %>"> ... <div id="price"> <%= in_place_editor_field :item, :price

I am serializing a data object (FooData) into an ActiveRecord column (Foo). I''d like to be able to do delegate methods to the data class if the Foo class doesn''t have that attribute. So instead of: f = Foo.new f.data.item1 I''d like to do: f = Foo.new f.item1 I was hoping that I could add a method_missing method to my Foo class and call methods in the FooData class

I thought I''d seen some discussion on this, but can''t find it. I have a text area that I''d like to save on blur unless the user clicks cancel. Anyone got a nice example of this? It''s non-obvious to me how I force the submit via javascript. Thanks, pt. -- Parker Thompson http://www.parkert.com/ 510.541.0125

Hey, I installed the rjs plugin yesterday and started using it for one set of views. Today I notice that in an entirely separate controller/template I''m seeing this error: TypeError (can''t dup NilClass): /vendor/plugins/javascript_generator_templates/lib/add_rjs_to_action_controller.rb:41:in `dup''

I have the following models: class Order < ActiveRecord::Base belongs_to :billing_address belongs_to :shipping_address accepts_nested_attributes_for :billing_address accepts_nested_attributes_for :shipping_address, :reject_if => proc { |attributes| attributes[''has_shipping_address''] != ''1'' } def after_initialize self.build_billing_address

Hello all, I have what is conceptually a pretty simple poblem, but can''t think of an obvious solution. I have a group of objects (@items), that I wish to render as rows. Items have dates, and I wish to group them by that date, inserting a header row each time the date changes e.g.: header row row 11/11/2004 row 11/11/2004 header row row 11/23/2004 I''m currently

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

All, Can anyone see what''s happening here? ================== migration ======================= class CreateGreetings < ActiveRecord::Migration def self.up create_table :greetings do |t| t.string :greet t.string :language t.integer :count t.timestamps end end def self.down drop_table :greetings end end ================== greeting.rb

Hi guys, I''m 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

Guys, I''ve run across an interesting scenario with my migrations, and I hope you might share some insight. Let''s say I have 3 migrations and two Models (Person and Car): 001_initial_schema.rb 002_data_load.rb 003_add_car_association.rb The first creates the initial schema...the second loads default data using model objects of Person to do so, and the third creates a new

I have three model objects: 1. Document 2. Section 3. Content According to my requirements a Document must have at least one Section. Similarly a Section must have at least one Content. How can I add a Section when a Document is created and add a Content when a Section is created? My code: class Document < ActiveRecord::Base has_many :sections end class Section < ActiveRecord::Base

Hi all, I''m having issues with Unicorn and connecting to RabbitMQ using the tmm1-amqp gem. I''ve tried lots of approaches. The classic initializer with Thread.new { EM.run } for the Rails app and even tried using the Qusion library. (https://github.com/danielsdeleo/qusion) I''ve made a simple mod to Qusion for it to monkey patch unicorn too. The code looks

I''ve been bringing up a good basica framework for applications at work. To give decent security I''ve been implementing the Rails Recipie for Authorization of function calls modeled on the book''s implementation. (Changes for our environment were added..but are minor.) Since I initially let Rails create the join table between two data tables with a HABTM relationship....I
