ruby-on-rails - 处理像回形针“系统”文件夹这样的文件夹，在共享中符号链接

Question

我有一个由 gem 上传的资产（通过回形针）的文件夹，它们存储在不同的文件夹ckeditor_assets中。

我想用 capistrano 处理这个文件夹，就像处理文件system夹上传回形针一样。

我怎样才能做到这一点？它将包含客户数据，因此很重要。

我解决了这个问题：http ://www.simonecarletti.com/blog/2009/02/capistrano-uploads-folder/

为了将来参考，我报告了博文的一部分，它基本上在 capistranoshared文件夹中创建了一个目录，并且每次都对其进行符号链接。

# ==============================
# Uploads
# ==============================

namespace :uploads do

  desc <<-EOD
    Creates the upload folders unless they exist
    and sets the proper upload permissions.
  EOD
  task :setup, :except => { :no_release => true } do
    dirs = uploads_dirs.map { |d| File.join(shared_path, d) }
    run "#{try_sudo} mkdir -p #{dirs.join(' ')} && #{try_sudo} chmod g+w #{dirs.join(' ')}"
  end

  desc <<-EOD
    [internal] Creates the symlink to uploads shared folder
    for the most recently deployed version.
  EOD
  task :symlink, :except => { :no_release => true } do
    run "rm -rf #{release_path}/public/uploads"
    run "ln -nfs #{shared_path}/uploads #{release_path}/public/uploads"
  end

  desc <<-EOD
    [internal] Computes uploads directory paths
    and registers them in Capistrano environment.
  EOD
  task :register_dirs do
    set :uploads_dirs,    %w(uploads uploads/partners)
    set :shared_children, fetch(:shared_children) + fetch(:uploads_dirs)
  end

  after       "deploy:finalize_update", "uploads:symlink"
  on :start,  "uploads:register_dirs"

end
