将ROR项目从development环境改为production环境时，运行rake assets:precompile后，

ckeditor的界面就无法完整显示？！ @_@??

出现 ActionController::RoutingError (No route matches [GET] "/assets/ckeditor/config.js")

solution ：creating a rake task that couples with "assets:precompile" to create "non-digested" versions of the ckeditor asset files after pushing to production，and made a /lib/tasks/ckeditor.rake file with the following task.

就是说在 /lib/tasks目录下创建个新的文件ckeditor.rake，在该文件中添加下面代码：

# lib/tasks/ckeditor.rake
require 'fileutils'
desc "Create nondigest versions of all ckeditor digest assets"
task "assets:precompile" do
  fingerprint = /\-[0-9a-f]{32}\./
  for file in Dir["public/assets/ckeditor/**/*"]
    next unless file =~ fingerprint
    nondigest = file.sub fingerprint, '.'
    FileUtils.cp file, nondigest, verbose: true
  end
end

然后在 /config/application.rb中添加下面代码：

config.autoload_paths += %W(#{config.root}/app/models/ckeditor)
config.assets.precompile += Ckeditor.assets
config.assets.precompile += %w(ckeditor/*)

接着在 /app/assets/javascripts/application.js中添加：

//= require ckeditor/ckeditor

在 /config/route.rb 中，

mount Ckeditor::Engine => '/ckeditor'

 重新运行 rake assets:precompile

 这样ckeditor的界面就能完整显示啦！！
