1： 直接用SQL查询，而不用迁移
2：CREATE TABLE `company_info`  没有对应的model
3:class Department < ActiveRecord::Base
    has_many :roles,:order=>'name'  为什么department有角色
4：权限model 有点意思：class Right < ActiveRecord::Base
    has_and_belongs_to_many :roles
    validates_presence_of :name,:message=>'没有填写频道名称'
end

5:socket: /opt/lampp/var/mysql/mysql.sock是什么意思？

=> Rails 2.3.2 application starting on http://0.0.0.0:3000
Your config/boot.rb is outdated: Run "rake rails:update".
rake rails:update
install -c -m 0755 E:/InstantRails20/ruby/lib/ruby/gems/1.8/gems/rails-2.3.2/lib/tasks/../../bin/dbconsole script/dbcons
ole （已经将boot.rb升级了）
E:/worksapce/hamster/app/controllers/application.rb has been renamed to E:/worksapce/hamster/app/controllers/application
_controller.rb, update your SCM as necessary

htpp://localhost:3000
出现no such file to load -- application.rb
copy application_controller.rb application.rb 就可以了

RAILS_GEM_VERSION = '1.2.3' unless defined? RAILS_GEM_VERSION 现在还不支持2.3.2版本

—menu.rhtml 好像不太合理，完全更具权限的顺序排列，只是根据权限组分类了，菜单组=权限组
@session[:rights] = buildMenu '权限管理' 是关键
少一个模块管理，如果有就OK了，功能可以自己定义了
可能是这样的层次，最上层是模块==频道组==频道， 频道组于模块是什么关系？
很多模块的_menu.rhtml 是类似的，如何将它重组，实现DRY
权限管理这个模块的名字应该叫组织管理比较好，因为它有部门、角色、用户、权限等管理组成
没有LOGOUT功能
