問題與部署我的紅寶石軌應用程序

Question

我試圖解決我最近有一個問題，部署從github生產分支cap: production deploy:migrations到我的服務器。

我看到了一個潛在的解決方案是按照這個頁面：http://www.kudelabs.com/2012/03/28/rails-3-2-cap-deploy-with-assets

但是我在rake assets:precompile部分有錯誤，本地運行它。終端建議我做 bundle exec rake assets:precompile，我做到了，但我得到了以下幾點：

root@ubuntu:~/myapp# bundle exec rake assets:precompile

誰能告訴我在哪裏的問題可能是什麼？

Answer 1

如果這是初始部署，儘量去除

load 'deploy/assets' 

然後嘗試

cap deploy:setup 
cap deploy:cold 

在這種情況下，你的應用程序將被部署，但沒有任何資產:) 然後，你需要加上：

#to the top of your deploy.rb namespace :deploy block 
namespace :assets do 
    task :precompile, :roles => :web do 
    from = source.next_revision(current_revision) 
    if capture("cd #{latest_release} && #{source.local.log(from)} vendor/assets/ lib/assets/ app/assets/ | wc -l").to_i > 0 
        run_locally("rake assets:clean && rake assets:precompile") 
        run_locally "cd public && tar -jcf assets.tar.bz2 assets" 
        top.upload "public/assets.tar.bz2", "#{shared_path}", :via => :scp 
        run "cd #{shared_path} && tar -jxf assets.tar.bz2 && rm assets.tar.bz2" 
        run_locally "rm public/assets.tar.bz2" 
        run_locally("rake assets:clean") 
       else 
        logger.info "Skipping asset precompilation because there were no asset changes" 
       end 
      end 

      task :symlink, roles: :web do 
       run ("rm -rf #{latest_release}/public/assets && 
        mkdir -p #{latest_release}/public && 
        mkdir -p #{shared_path}/assets && 
        ln -s #{shared_path}/assets #{latest_release}/public/assets") 
      end 
     end 

然後重新檢查，如果你有這在你的production.rb

config.serve_static_assets = false 

# Compress JavaScripts and CSS 
config.assets.compress = true 

# Don't fallback to assets pipeline if a precompiled asset is missed 
config.assets.compile = false 

# Generate digests for assets URLs 
config.assets.digest = true 

所有這些工作後，改變一些東西在你的資產，例如在application.css添加新的生產線，這將告訴「任務：預編譯」來真的precomlile和上傳新的資產，因爲增加了新的資產..
