Making Configuration Files with YAML: RevisedPosted: January 2, 2009
So back in July 2007 I posted a blog on making configuration files with YAML, and I’ve been noticing a lot of readership on the old article. Because it seems that a lot of people are reading it I felt it was important to show how I apply this nowadays.
First I put my config.yml file within the /config/ directory within my Rails application. It looks something like this:
development: &non_production_settings :google_analytics: :api_key: "[Enter Google ID]" :site: :title: "[Title]" :address: "http://localhost:3000/" test: <<: *non_production_settings production: :google_analytics: :api_key: "[Enter Google ID]" :site: :title: "[Title]" :address: "[Address]"
Then, I create a new file called load_config.rb within the /config/initializers directory. You can name the file whatever you want – that’s just what I call it. This is where the actually YAML loading is going to happen – and this is what it looks like:
raw_config = File.read(RAILS_ROOT + "/config/config.yml") APP_CONFIG = YAML.load(raw_config)[RAILS_ENV]
Now any time I want to all one of these variables I just call it like:
<%= APP_CONFIG[:site][:title] %>
