If you are getting errors when using this in your test environment you forgot to add “test:” to your .yml file

The example in this article had production and dev, but for some reason omits test

It works for my Rails 2.0.2 project:

1
2
3
4
5

# app-specific config
require 'ostruct'
require 'yaml'
config = OpenStruct.new(YAML.load_file("#{RAILS_ROOT}/config/chef.yml"))
::AppConfig = OpenStruct.new(config.send(RAILS_ENV))

Test:

1
2
3

def test_test_base
assert_not_nil AppConfig.test_base
end

Passes. When I change it to assert_nil it fails, and I see that it was actually set.

This code does’t work in ‘test’ environment (Rails 2.0.2).

Problem with:

1	env_config = config.send(RAILS_ENV)

It’s strange that config.test() work, but confg.send('test') not.
I don’t know why. Can anyone explain this behaivor?

Hi Dmitry,

I have expanded your idea into a plugin: http://agilewebdevelopment.com/plugins/application_configuration

I have been using your setup with great pleasure in couple of last projects.

Many thanks!

Many thanks for the great idea. I've decided to go further and now config file is parsed with ERB, one can have another file to override the values in the main file (when you place config.yml to svn and need specific values in your working copy) and config values can not be overwritten in the application (by mistake). Please check it out.
