使用 Rails Task 同步 cancan's actions as permissions 到数据库中

boboism — Sat, 08 Dec 2012 11:17:43 +0800

前些天看到社区中一篇 @beiersi 写的《写一点 CanCan 结合数据库使用的简单实现》。觉得不错，但是少了自动同步到数据库的一些实现。后来参考了 cancan 的 wiki 《Abilities in Database》，写成任务来执行同步，在 jruby171 下面能用，应该 mri193 也没问题。

desc "Synchronize controllers' actions as permissions to database"
task :sync_perm => :environment do
  synchornize_controllers_actions_as_permissions_to_db
end

def synchornize_controllers_actions_as_permissions_to_db
  write_permission(:action => "manage", :subject => "all", :action_description => "All operations", :subject_description => "Everything")

  Dir.new("#{Rails.root}/app/controllers").entries.each do |controller|
    controller.camelize.gsub(".rb","").constantize.new if controller =~ /_controller/
  end
  ApplicationController.subclasses.each do |controller|
    clazz = controller.name.gsub("Controller","").singularize.understore
    actions = controller.action_methods.reject{|action| action.to_s.index("_callback")}
    write_permission(:action => "manage", :subject => clazz, :action_description => "All operations", :subject_description => clazz.camelize, :alias_actions => actions.join(","))
    actions.each do |action|
      cancan_action, action_description = eval_cancan_action(action)
      write_permission(:action => cancan_action, :subject => clazz, :action_description => action.camelize, :subject_description => clazz.camelize, :alias_actions => action)
    end
  end
end

def eval_cancan_action(action)
  case action.to_s
  when "index", "show", "search"
    cancan_action = "read"
    action_desc = I18n.t :read
  when "create", "new"
    cancan_action = "create"
    action_desc = I18n.t :create
  when "edit", "update"
    cancan_action = "update"
    action_desc = I18n.t :edit
  when "delete", "destroy"
    cancan_action = "delete"
    action_desc = I18n.t :delete
  else
    cancan_action = action.to_s
    action_desc = "Other: " << cancan_action
  end
  return cancan_action, action_desc
end

def write_permission(options={})
  options = {:action => "", :subject => "", :action_description => "", :subject_description => "", :alias_actions => ""}.merge options
  permission = Permission.where(:subject => options[:subject], :action => options[:action]).first || Permission.new
  options[:alias_actions] = Set.new((permission.alias_actions||"").split(",")|(options[:alias_actions]||"").split(",")).delete_if(&:empty?).to_a.sort.join(",")
  permission.update_attributes(options)
end

@huacnlee ，关于一点不解的是主题列表界面的排序问题以及帖子的创建时间好像都没有。是否考虑一下以后实现？？

Rails 在 VMWare 界面登录 console 运行时响应非常慢

boboism — Sun, 06 May 2012 09:45:36 +0800

各位，我在 vmware 下开了个 UBUNTU SERVER，在里面用 RVM 装 ruby，rails 是 323。但是当我在 vmware 界面登录 console，运行 rails s 时，用网页访问响应非常慢，但是如果我在客户端 ssh 连进 ubuntu 运行时候就非常快？这个啥原因？各位试过吗？
