不知道哪邊弄錯了用capistrano deploy 想啟動delayed_job 卻好像都沒反應
後來終於看到 有script/delayed_job run的指令 這個動作才可以讓你看到你錯在哪, start 只會無聲無息
<br />set :env, 'production' #不知道為範例的rails_env 都抓不到值<br /><br />namespace :delayed_job do<br /> desc "Start delayed_job process" <br /> task :start, :roles => :app do<br /> run "cd #{current_path}; ruby script/delayed_job start -- #{env}" <br /> end<br /><br /> desc "Stop delayed_job process" <br /> task :stop, :roles => :app do<br /> run "cd #{current_path}; script/delayed_job stop -- #{env}" <br /> end<br /><br /> desc "Restart delayed_job process"<br /> task :restart, :roles => :app do<br /> run "cd #{current_path}; script/delayed_job restart -- #{env}" <br /> end<br />end<br /><br />
