Question

Is it possible without having to access the website to tell rails to perform a cache of all the files within the application.html.erb page together?

I have the following code in my page:

<%= stylesheet_link_tag ‘reset’,’forms’,’layout’,’common’,’pages’, :cache => ‘_cached’ %>

This will combine everything together into a _cached.css file when the website is loaded for the first time in production mode. However, I would like for the file to be regenerated once the website is initialized.

So the steps would be

• start the rails app
• remove the existing _cached.css file
• tell rails to recreate the file based on the code within the application.html.erb file
• website is live…

Any ideas on how todo this? Can be down as a rake command or something?

Answer 1

After setting up a rake task that accesses the website files once the website is loaded, this works.

namespace :assets do

  desc "Removing existing cached files"
  task :clear => :environment do
    FileUtils.rm(Dir['public/javascripts/_cached.js']) 
    FileUtils.rm(Dir['public/javascripts/_ie6.js']) 
    FileUtils.rm(Dir['public/stylesheets/_cached.css'])
  end

  desc "Recreate the javascripts/stylesheets cache."
  task :generate => [:environment, :clear] do
    puts "Recreate the javascripts/stylesheets cache"
    ActionController::Base.perform_caching = true
    app = ActionController::Integration::Session.new(ActionController::Dispatcher.new)
    app.get '/'
  end

end
