Rails 3.2 initializers load order causes failures when config.cache_clases == true

Hey all, we are in the midst of upgrading our app from rails 3.0.20 to
rails 3.2.13. As part of this upgrade we are experiencing an issue in
test suite in which when cache classes is turned on our models are
before our initializers. One of our initializers sets up some constants
that one of our models uses at load time. Has anyone experienced
that seems similar to this and if you could you point me the right
direction to finding a solution.

example of what is happening:
ApiServer::Application.configure do

The test environment is used exclusively to run your application’s

test suite. You never need to work with it otherwise. Remember


your test database is “scratch space” for the test suite and is


and recreated between test runs. Don’t rely on the data there!

config.cache_classes = true

Log error messages when you accidentally call methods on nil.

config.whiny_nils = true

Show full error reports and disable caching

config.consider_all_requests_local = true
config.action_controller.perform_caching = false
config.consider_all_requests_local = true

Set host for using url helpers in mailers

config.action_mailer.default_url_options = { :host => “localhost:3000”

Disable request forgery protection in test environment

config.action_controller.allow_forgery_protection = false

config.active_support.deprecation = :log

Tell Action Mailer not to deliver emails to the real world.

The :test delivery method accumulates sent emails in the

ActionMailer::Base.deliveries array.

config.action_mailer.delivery_method = :test

Use SQL instead of Active Record’s schema dumper when creating the


This is necessary if your schema can’t be completely dumped by the

schema dumper,

like if you have constraints or database-specific column types

config.active_record.schema_format = :sql

config.supports_ssl = false
config.force_ssl = false


config = YAML.load(Rails.root.join ‘config’, ‘adapters.yml’)[Rails.env]
config do |k, v|
const_set “ADAPTER_#{k}”, v

class BaseAdapter < ActiveResource::Base
self.path = ADAPTER_PATH
