ruby-on-rails - 有没有一种方法可以使用Capistrano(或类似工具)与Rails控制台进行远程交互

Question

我很喜欢capistrano如何简化我的部署工作流程，但是通常情况下，插入更改会遇到一些问题，这些问题我需要通过控制台登录服务器进行故障排除。

有没有一种方法可以使用capistrano或其他远程管理工具从本地终端与服务器上的Rails控制台进行交互？

**更新:

cap shell看起来很有前途，但是当您尝试启动控制台时，它会挂起:

cap> cd /path/to/application/current
cap> pwd
 ** [out :: application.com] /path/to/application/current
cap> rails c production
 ** [out :: application.com] Loading production environment (Rails 3.0.0)
 ** [out :: application.com] Switch to inspect mode.

如果您知道解决方法，那就太好了

我发现了基于https://github.com/codesnik/rails-recipes/blob/master/lib/rails-recipes/console.rb的不错的解决方案

desc "Remote console" 
task :console, :roles => :app do
  env = stage || "production"
  server = find_servers(:roles => [:app]).first
  run_with_tty server, %W( ./script/rails console #{env} )
end

desc "Remote dbconsole" 
task :dbconsole, :roles => :app do
  env = stage || "production"
  server = find_servers(:roles => [:app]).first
  run_with_tty server, %W( ./script/rails dbconsole #{env} )
end

def run_with_tty(server, cmd)
  # looks like total pizdets
  command = []
  command += %W( ssh -t #{gateway} -l #{self[:gateway_user] || self[:user]} ) if     self[:gateway]
  command += %W( ssh -t )
  command += %W( -p #{server.port}) if server.port
  command += %W( -l #{user} #{server.host} )
  command += %W( cd #{current_path} )
  # have to escape this once if running via double ssh
  command += [self[:gateway] ? '\&\&' : '&&']
  command += Array(cmd)
  system *command
end
