Ask Capistrano在鏈接（符號鏈接）文件之前運行任務

Question

我一直在嘗試編寫capistrano腳本，其中我的應用程序目錄（support/config/#{rails_env}）的複製配置文件爲capistrano的shared directory（共享/配置）

rails_env => 'staging'

這樣當Capistrano的運行first time它排序副本從support/config/#{rails_env}目錄共享/ config目錄中的文件，但在此之前完成

它需要運行前將此文件作爲由Capistrano即鏈接

set :linked_files, %w{config/api_config.yml}

，以使關聯任務亙古不失敗（因爲它要求任務所需的文件，在共享目錄存在）

這裏是我的Capfile（沒什麼特別的，因爲大部分的東西是做我的capistrno）

set :application, 'custom-api' 
set :repo_url, '' 

# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp } 
set :rails_env, 'staging' 
set :deploy_to, '/var/apps/staging/custom-api' 
set :scm, :git 

set :format, :pretty 
set :log_level, :debug 
set :rvm_type, :user # Defaults to: :auto 
set :rvm_ruby_version, 'ruby-1.9.3@484@custom-api' 
#set :rvm_custom_path, '~/.myveryownrvm' # only needed if not detected 
# set :pty, true 
set :linked_files, %w{config/mongoid.yml config/api_config.yml} 
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system} 

#set :default_env, { path: "$HOME/.rvm/#{}:$PATH" } 
set :keep_releases, 5 
#SSHKit.config.command_map[:cp_r] = "cp -r" 

## Need to run before the file is linked 
#before 'deploy:[task_name]' , 'deploy:copy_files' 

namespace :deploy do 
    desc 'Copy files from application to shared directory' 
    ## copy the files to the shared directories 
    task :copy_files do 
    on roles(:app) do 
     execute :cp ,'-r',release_path.join('support/config'),shared_path 
    end 
    end 

    desc 'Restart application' 
    task :restart do 
    on roles(:app), in: :sequence, wait: 5 do 
     # Your restart mechanism here, for example: 
     execute :touch, release_path.join('tmp/restart.txt') 
    end 
    end 

    after :restart, :clear_cache do 
    on roles(:web), in: :groups, limit: 3, wait: 10 do 
     # Here we can do anything such as: 
     # within release_path do 
     # execute :rake, 'cache:clear' 
     # end 
    end 
    end 
    after :finishing, 'deploy:cleanup' 
end 

所有我需要的是像做

before 'deploy:[task_name]' , 'deploy:copy_files'

新增注：我們ING Capistrno 3.0.1

根據他們documentation，任務被稱爲部署：符號鏈接：共享。我會裝點，像你的例子：

before 'deploy:symlink:shared', 'deploy:copy_files' 

要知道，當你裝點實際任務一樣，它會被稱爲每一個任務被調用時。
