Converts a Ruby object into a hash. This is not intended for object serialization or mapping, but instead for saving the information contained in an object to a document database, JSON file, etc...

hashject.rb

require 'yaml'
require 'json'

# The Ruby object called 'objie' contains information
# that need to be saved in a document database. 'objie'
# may or may not contain nested objects
yaml = objie.to_yaml 
# Alternatively: yaml = YAML::load('objie.yml')

# Remove the Ruby object's YAML header
behead = yaml.lines[1..-1].join

# Remove the YAML header of each nested object
# while keeping the indentation intact
behead.gsub!(/^([- ]*)!ruby\/object:.*$\n\s*/,'\1')
behead.gsub!(/\s*!ruby\/object:.*$/,'')

# With all object headers removed, the remainder is a hash
hash = YAML::load(behead)

# Depending on the needs one may convert the hash into JSON
json = hash.to_json
