JavaScript缓存，Rails和Apache乘客？

Question

I have written a Capistrano recipe to remove the all.js cached JavaScript file and tell the server to restart, but it still doesn't work right. And inevitably I have to go manually delete the all.js file and then manually restart Apache. (touching restart.txt doesn't always work).

Anybody have a working solution to this problem?

Here is the current recipe:

desc "Package Javascripts"  
    task :package_javascripts, :roles => :web do
      sudo %{rm -f #{current_path}/public/javascripts/all.js}
      javascripts.each do |javascript|
        run %{/usr/bin/ruby #{current_path}/lib/jsmin.rb < \
              #{current_path}/public/javascripts/#{javascript}.js >> \
              #{current_path}/public/javascripts/all.js}
      end
      run "touch #{current_path}/tmp/restart.txt"
    end

Answer 1

Did you linked you task somewhere:

after "deploy:symlink", :package_javascripts

Also change restart line to:

run "rm -f #{current_path}/tmp/restart.txt ; touch #{current_path}/tmp/restart.txt"
