ruby操作文件

require 'app/configuration'
module RubyAMF
  module Configuration
    #set the service path used in all requests
    # RubyAMF::App::RequestStore.service_path = File.expand_path(RAILS_ROOT) + '/app/controllers'

    # => CLASS MAPPING CONFIGURATION
    ClassMappings.register(
      :actionscript  => 'Stock',
      :ruby          => 'Stock',
      :type          => 'active_record',
      :attributes    => ["code", "name"])
    end
end
ClassMappings.register(
      :actionscript  => 'Rolestock',
      :ruby          => 'Rolestock',
      :type          => 'active_record',
      :associations  => ["stock"],
      :attributes    => ["id", "cost", "amount"])


上面算是整个文件吧，之后我在另一个同等级路径文件下要操作这个文件


  File.open("rubyamf_config.rb") do |file|
    while line = file.gets
