Question

I am serving a Rails 3 application from a subdirectory with Passenger and Apache:

<VirtualHost *:80>
  RackBaseURI /streamspons
  <Directory /var/www/html/streamspons>
     AllowOverride all
     Options -MultiViews 
  </Directory>
</VirtualHost>

In my controller I cache a page:

caches_page :banner

When the #banner action is called, the page is written out to public/, but inside of another directory named for the app’s subdirectory (in other words, the entire request string including the subdirectory is in the cache path):

Started GET "/streamspons/decks/2/banner.js"
...
Write page /var/www/public/apps/streamspons/releases/20110316162902/public/streamspons/decks/2/banner.js

When this action is requested again, it misses the cache and runs the action again because the cached page should be at public/decks/2/banner.js instead of public/streamspons/decks/2/banner.js.

Where am I going wrong?

Answer 1

In Rails 3.0.1 I added this to my app/controllers/application_controller.rb:

class ApplicationController < ActionController::Base
  ...

  # override this class method to strip the path to the
  # rails app root from the request path
  def self.page_cache_path(path)
    path.gsub!(%r[^/streamspons], "")
    page_cache_directory + page_cache_file(path)
  end
end

In latest Rails this might look like:

class ApplicationController < ActionController::Base
  ...

  def self.page_cache_path(path, extension = nil)
    path.gsub!(%r[^/streamspons], "")
    page_cache_directory + page_cache_file(path, extension)
  end
end
