#    `-- db
#        |-- seeds
#        |    |-- development
#        |    |   |-- books.yml
#        |    |   `-- users.yml 
#        |    `-- production

#
#  And put this block in your `seeds.rb` file:
#
Dir[Rails.root.join('db', 'seeds', Rails.env, '*.yml')].each do |seed|
  documents = YAML.load_file(seed)
  klass = File.basename(seed, '.yml').classify.constantize
  documents.each do |doc|
    klass.create(doc.last)
  end
