Hash inside YAML file?

Question

I want to include a hash and list inside a YAML file that I\'m parsing with the following command:

APP_CONFIG = YAML.load_file(\"#{RAILS_ROOT}/config/config.

Ceilingfish's answer is maybe technically correct, but he recommends to use a white space at the end of a line. This is prone to errors and is not a good practice!

This is how I would do it:

Create a settings.yaml file with the following contents:

---
feeds:
  :url: 'http://www.google.com'
  :label: 'default'

This will create the following hash after the YAML file has been loaded:

irb(main):001:0> require 'yaml'
=> true
irb(main):002:0> YAML.load_file('settings.yaml')
=> {"feeds"=>{:url=>"http://www.google.com", :label=>"default"}}
irb(main):003:0> 

In this example, I also use symbols since this seems to be the preferred way of storing Ruby keys in Ruby.
