Hello, I have a question on cache expiration only working from the web, and not from the console or from a rake task.
I have 2 models, Post e Comments. I have this page /archives where I list all old posts. I created a controller 'archives', where I have a page cache (caches_page :index). I need to expire this page cache, every time a Post or Comment is created/updated/destroyed. Using sweepers, this works 100%. ( http://www.railsenvy.com/2007/2/28/rails-caching-tutorial#sweepers) The problem is that, now, I implemented spam moderation by Akismet. So when a new comment is created in the database, it gets a 'pending' status. And there's a rake task that runs every x minutes, in order to check all 'pending' comments against the Akismet database, and only then comments earn an 'approved' or 'spam' status. And it's only then that I should expire the /archives page. So I need to expire a cached page, from something that happens outsite a controller. And it seems the only situation a sweeper works is when the event is triggered by the web. If I open the console, add a new comment to a post, nothing happens (ok!). And now I run the Akismet check, and assuming it gives the comment an 'approved' status, the cache is not expired, when it should be. I tried to use Observers, from the Rails docs ( http://www.railsbrain.com/api/rails-2.2.2/doc/index.html?a=M001871&name=observe ). In environment.rb I added the line: config.active_record.observers = :archives_observer I created the file app/models/archives_observer.rb with: class ArchivesObserver < ActiveRecord::Observer observe :post, :comment def after_save(record) expire_page(:controller => 'archives', :action => 'index') end end But I get an error: NoMethodError: undefined method `expire_page' for #<ArchivesObserver:0x247eddc> I tried this also: class ArchivesObserver < ActionController::Caching::Sweeper (...) In this case, there's no error, and it does nothing at all. The public/archives.html just stays there. I'm trying my best to avoid hacking it, using a simple File.delete :) Like the code below: # File rails/actionpack/lib/action_controller/caching/pages.rb, line 65 65: def expire_page(path) 66: return unless perform_caching 67: 68: benchmark "Expired page: #{page_cache_file(path)}" do 69: File.delete(page_cache_path(path)) if File.exist?(page_cache_path(path)) 70: end 71: end Is there a way to expire pages without having to hack it?
