Unicorn不是由upstart脚本运行.

rvm 1.25.23 ruby​​ 2.1.1 Rails 4.1

配置/ deploy.rb

  desc 'Foreman init'
  task :foreman_init do
    on roles(:all) do
      foreman_temp = "/home/deployer/tmp/foreman"
      execute  "mkdir -p #{foreman_temp}"
      execute "ln -s #{release_path} #{current_path}"
      within current_path do
        execute "cd #{current_path}"
        execute :bundle, "exec foreman export upstart #{foreman_temp} -a #{application} -u deployer -l /home/deployer/apps/#{application}/log -d #{current_path}"
      end
      sudo "mv #{foreman_temp}/* /etc/init/"
      sudo "rm -r #{foreman_temp}"
    end
  end

/etc/init/depl-web-1.conf

start on starting depl-web
stop on stopping depl-web
respawn

env PORT=5000

setuid deployer

chdir /home/deployer/apps/depl/current

exec bundle …

我正在尝试解析一个大型XML文件.我正在使用Saxerator.

我的哈希有一种树:

obj= {
  "id"=>'1', "groups" =>{
  "group" =>[
   {"id"=>"2", "groups"=>{}},
   {"id"=>"3", "groups"=>{}},
   {"id"=>"4", "groups"=>{
     "group"=>[
       {"id"=>"5", "groups"=>{}},
       {"id"=>"6", "groups"=>{}},
     ]}}
]}}

我事先并不知道树的深度.我有一个问题.我不知道如何在数组中转换它.结果应该是这样的:

[{"id"=> "1", "parent_id"=> "0"},
{"id"=> "2", "parent_id"=> "1"},
{"id"=> "3", "parent_id"=> "1"},
{"id"=> "4", "parent_id"=> "1"},
{"id"=> "5", "parent_id"=> "4"},
{"id"=> "6", "parent_id"=> "4"}]

有什么想法吗？
