ruby-on-rails – 在使用capistrano部署到amazon EC2时,资产不会

我们的预编译资产选项在生产中没有正确编译,因此,我们无法使用最后开发的功能,因为它们严重依赖于JS.

没有试图影响任何人如何分析这个问题,这是我试图让它工作的一些：

>本地预编译资产,推送到github repo,从本地计算机部署到ec2. cap部署是本地的,代码被推送到ec2是github上的代码.
>根据建议尝试使用capistrano任务.在Capfile中使用加载’deploy’assets’,并使cap部署：安装任务执行其任务.
>使用选项cap deploy：assets：clean然后cap deploy：assets：precompile
尝试从public中移除资源,然后在deploy.rb中使用pipeline_precompile任务
>过期的资产,迫使rails预编译在application.rb中改变asset.versions的一切
>尝试在environment / production.rb中的config.assets上的不同组合
>最后,尝试删除生产中的公共/资产,并使用RAILS_ENV = production bundle exec rake assets预编译：预编译

该应用程序只是不使用新的JS文件.如果您在repo或服务器本身检查代码,我引用了一个简单的评论到name.js.coffee(“#显示和隐藏菜单,取决于数据库上的数据”在第xxx行),这不是在编译的asset.js在生产中.这是一个快速测试,以确保最近的资产被使用.

这里的整个问题是js和css文件,没有那么多的轨道.这就是为什么这么难测试或找到..因此最近js框架的普及的原因之一.如果出现问题,您不必杀死自己,寻找问题的位置.如果问题出在ruby或者轨道上,通常不需要花太多时间才能找到.一旦你得到了js,css和浏览器的兼容性,那么这就是现在的问题.

这是我的deploy.rb文件.跑道3.2.12 ruby??-1.9.3-p327：

# $:.unshift(File.expand_path('./lib',ENV['rvm_path']))

正在工作的新/替代(deploy_new2.rb)文件：

namespace :deploy do

  # end

  task :restart,:except => { :no_release => true } do
    run "cd #{release_path} && touch tmp/restart.txt"
  end

  # If you enable assets/deploy in Capfile,you do not need this
  # task :pipeline_precompile do
  #   # run "cd #{release_path}; RAILS_ENV=#{rails_env} bundle exec rake assets:precompile"
  #   # precompile assets before deploy and upload them to server

  #   # top.upload "public/assets","#{release_path}/public/assets",:via =>:scp,:recursive => true
  # end
end

# you do not need to this,because you already add require 'bundler/capistrano'
# before "deploy:assets:precompile","bundle:install"

和./Capfile：

load 'deploy'
# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'
load 'config/deploy' # remove this line to skip loading any of the default tasks
