ruby-on-rails - 在 Capistrano 配方中将 "before"和 "after"放在哪里？

Question

愚蠢的问题，但我们有一个损坏的 Capistrano 配方，我想验证一下我们没有错误地使用 after 和 before？

这些之前和之后的任务属于 :deploy 命名空间 block 内还是外部？我看到了 here 的例子.

这是有问题的deploy.rb的摘录:

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  # copy database.yml into project
  task :copy_database_config do
    production_db_config = "/Library/RoRconfig/#{application}.yml"
    run "cp #{production_db_config} #{current_release}/config/database.yml"
    `puts "replaced database.yml with live copy"` 
  end

  task :pipeline_precompile do
    run "cd #{release_path}; RAILS_ENV=production rake assets:precompile"
  end

  after "deploy:update_code", "deploy:pipeline_precompile"         ### <---
  before "deploy:finalize_update", "deploy:copy_database_config"   ### <---
end

我使用的设置类似于:

after :deploy, "deploy:update_code", "deploy:pipeline_precompile"
before :deploy, "deploy:finalize_update", "deploy:copy_database_config"

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  # copy database.yml into project
  task :copy_database_config do
    production_db_config = "/Library/RoRconfig/#{application}.yml"
    run "cp #{production_db_config} #{current_release}/config/database.yml"
    `puts "replaced database.yml with live copy"` 
  end

  task :pipeline_precompile do
    run "cd #{release_path}; RAILS_ENV=production rake assets:precompile"
  end
end
