Ruby On Rails in UA/Программирование на ROR/Используем active_record без рельсов

Вот появилась необходимость собединиться без рельс с базой
Использовал конекшин к базе и конфигурационнай файл рельсов

>> require 'rubygems' => false >> require 'active_record' => true >> require 'action_mailer' => [] >> require 'yaml' => [] >> ENV['RAILS_ENV'] = 'development' => "development" >> APP_DIR = File.join(File.dirname(File.expand_path(__FILE__)), '..') => "/home/wr/tmp/tmp/testdrb/script/.." >> Dir.chdir(APP_DIR) => 0 >> db_config = YAML::load(File.open("#{APP_DIR}/config/database.yml")) => {"development"=>{"socket"=>"/var/lib/mysql/mysql.sock", "encoding"=>"utf8", "username"=>"igp", "adapter"=>"mysql", "host"=>"localhost", "password"=>nil, "database"=>"igp_development"}, "production"=>{"encoding"=>"utf8", "username"=>"root", "adapter"=>"mysql", "host"=>"localhost", "password"=>nil, "database"=>"igp_production"}, "test"=>{"socket"=>"/var/lib/mysql/mysql.sock", "encoding"=>"utf8", "username"=>"root", "adapter"=>"mysql", "host"=>"localhost", "password"=>nil, "database"=>"igp_test"}} >> ActiveRecord::Base.establish_connection(db_condig[ENV['RAILS_ENV']] ) NameError: undefined local variable or method `db_condig' for main:Object from (irb):10 >> ActiveRecord::Base.establish_connection(db_config[ENV['RAILS_ENV']] ) => #<ActiveRecord::Base::ConnectionSpecification:0x2aaab0a4a788 @adapter_method="mysql_connection", @config={:encoding=>"utf8", :password=>nil, :adapter=>"mysql", :username=>"igp", :host=>"localhost", :socket=>"/var/lib/mysql/mysql.sock", :database=>"igp_development"} >> ActiveRecord::Base.establish_connection(db_condig[ENV['RAILS_ENV']] ) => #<ActiveRecord::Base::ConnectionSpecification:0x2aaab0a4a788 @adapter_method="mysql_connection", @config={:encoding=>"utf8", :password=>nil, :adapter=>"mysql", :username=>"igp", :host=>"localhost", :socket=>"/var/lib/mysql/mysql.sock", :database=>"igp_development"}
В итоге получили конешин и возможсть загружать далее класы моеделй и работать с ними

После установленного конекта подключаем нужныю нам модель User
>> require "#{APP_DIR}/app/models/user.rb" => ["User"] >> User.find(:all) => [#<User id: 1, login: "asdrr", email: "rebisall@mail.ru", first_name: "qwerqwer", last_name: "adfasdf", business_id: nil, crypted_password: "5c2aeff602cffdcef4a93ee8cb0acb569ece0091", salt: "fef6c55b6f6d10562f4f370a8050ab83519063bc", created_at: "2007-12-19 13:18:50", updated_at: "2007-12-19 13:18:50", remember_token: nil, remember_token_expires_at: nil, activation_code: "e28b1c84164537663ef6c074bdce9fbcc007dee3", password_reset_code: nil, activated_at: nil>]
