I've been trying to track this down for a while now and have yet find the solution...this problem appears only to occur in production environment with multiple mongrels.
We've got several controllers using conditional action caching using cache_fu plugin. Some actions work great, as I expect, others seem to work intermittently at mongrel startup, but quit working after a while.
So for example, the index action in a help controller works fine (this is picked up by a default route):
class HelpController < ApplicationController caches_action :index => {:ttl => 1.hour, :if => :cacheable?}
def index end end
However, some actions, including the main site index action seems to fail miserably.
Uses this route:
# Default welcome Route map.home '', :controller => "home"
# Note - c.flash_message below is to pick up redirects to index page with flash messages like one one logout, which will have a flash message ("You are now logged out," etc.)
class HomeController < ApplicationController before_filter :login_required, :except => [:index, :welcome, :public_profile, :test] before_filter :find_account_or_redirect, :except => [:index, :welcome, :public_profile, :test] caches_action :index => { :ttl => 30.minutes, :if => :cacheable? } , :cache_path => Proc.new {|c| c.flash_message }
def index respond_to do |format| format.html do unless logged_in? @favorite = FeatureItem.recent_favorites(1, 'entertainment') [0] @favorites = FeatureItem.recent_favorites(10, 'entertainment') render :action => 'welcome' and return false end . . . end end end . . . end
cacheable? method is in application controller (logged_in? is in restful_authentication library)
def cacheable? logged_in? ? false : true end
About four of the actions are working perfectly, the other four or so fail. Any insight would be highly appreciated...
