Question

我试图从app / controllers / users_controller继承@@ name和@@传递变量：

class UsersController < ApplicationController
require 'rubygems'
require 'net/ldap'
include AuthenticationsController
def save
@@name = params[:username]
@@pass = params[:password]
end
end

我想使用变量app / controllers / authentications_controller的类：

#!/usr/bin/env ruby 
require 'rubygems'
require 'net/ldap'
class AuthenticationsController
host = 'ip'
port = 389

username = @@name
password = @@pass

ldap = Net::LDAP.new
ldap.host = host
ldap.port = port
ldap.auth "uid=#{username},cn=users,cn=accounts,dc=aws,dc=company,dc=com", password

if ldap.bind 
puts 'YES!'
puts ldap.get_operation_result.message 
else
puts 'NO :-(' 
puts ldap.get_operation_result.message
end
end

错误：

未初始化的常量UsersController :: AuthenticationsController

请帮我解决此问题。提前致谢。

我会不建议在有其他选项时使用类变量来存储用户信息： -

 1. User a dedicated table user_ldap(any other name you want) to store and delete 
 2. Use session to store info at server side

类'变量继承
