similar to: Cache sweeping and render_component (my mistake or Rails bug?)

I''m using a cache sweeper class [1] to take care of some pretty complex sweeping. However, there is a problem with the current implementation. Namely, the sweeper gets called only when an action named in cache_sweeper is called using GET. As many methods where sweeper would be useful are using postback to send the form to the same action, this causes the cache to get swept when

I fired up the debugger and watched the code happen tonight. The problem occurs if the config.action_controller.perform_caching = true in your environment. It''s not set to true in development but it is set to true in production and staging. The problem occurs not in my controllers but in sweeping.rb (part of rails). Rails calls this code for every controller which was instantiated in

I created a sweeper ItemSweeper and saved it in app/models/item_sweeper.rb. Then I put this in my item_controller.rb: cache_sweeper :item_sweeper, :only => [:create, :destroy, :update] But now when I call the view action, I get this error: ActionView::TemplateError (undefined method `title'' for nil:NilClass) on line #5 of app/views/item/view.rhtml: 5: <H1

Folks, I''m going slightly crazy here - I implemented a Sweeper in an older app and used nearly the same exact code in my new app, yet I keep getting this ''value must be enumerable'' exception. Even after I cut most of the code away, I still get the error. If anyone can help, I would be much obliged. Notes: I''m using Engines... wonder if that could cause a

Hi, Why is cache_sweeper not a documented method? I was pretty sure it used to be, but I could be wrong. I can''t seem to find any information on it anymore in the online docs. As a side note, looking at the code for cache_sweeper it appears to only work with the :only option, not :except (ignores it)... what''s the reason for this? Thanks, Andrew

I created a script that I call by ''./script/runner -e production UpdateItems.get_new_items()'', which basically calls the model Item: Item.create(attributes...) I''ve set up a cache sweeper which removes caches after each create/destroy/update on Item, and it works fine when accessing controllers via the web server, but apparently doesn''t work via runner.

I''ve enabled page caching on a site I''m currently constructing. The sweeper is called upon any changes made to the model, as expected. The sweeper code is as follows: class PersonSweeper < ActionController::Caching::Sweeper observe Person def after_update(person) expire_staff_page end def after_destroy(person) expire_staff_page end def

Hello, I''m running Mongrel 0.3.13.3, cluster 0.2.0, and Rails 1.1.6 and I have a problem with a sweeper not having access to the controller instance. NoMethodError (undefined method `session'' for nil:NilClass): /app/models/audit_sweeper.rb:16:in `log'' /app/models/audit_sweeper.rb:9:in `after_update''

Hi, I''ve started to implement page caches but I''ve hit a brick wall getting a sweeper to clear the cache when needed. It seems that any models that I tell it to observe aren''t being observed properly. If I add the sweeper to a controller the initialize method runs, but no matter what I do the after_save/after_update callbacks aren''t running. Also if I try to

Hi, I upgraded from 1.0 to 1.1.1, now my cache sweepers acts up. They worked perfectly before he upgrade, now I get strange errors. I have an empty controller, it looks like this: class PageElementsController < ApplicationController cache_sweeper :element_sweeper def element_container_show render :inline=>"" end end The sweeper looks like this: class

After drawing many virtual blank stares in the IRC channel and finding zero results on the wiki for ''sweeper'' I''m left to wonder whether these are actually officially supported, or are on their way toward being deprecated. Is there a better way of expiring caches on model saves and deletions? Sincerely, Tom Lieber tom@alltom.com http://AllTom.com/

Hello, I am trying to expire fragments (or at least trigger their expiration) from a daemon that''s running in the background. The daemon is updating all kinds of important lists every few minutes from the background. So I have to find some way to DO or TRIGGER the fragment caching from this daemon. Unfortunately just using the normal commands like: expire_fragment :controller =>

Hi all I am trying to get VMX guests working on my new server here. The machine has a Pentium D 920 on an ASUS P5WD2-E motherboard. I''ve updated the BIOS to the latest 0401, which added the virtualization option. I am running a fresh installation of Gentoo (64-bit). When I try and run ''xm create'' on a vmx config file, I get the following error: Error: Error

I''ve got a Rails project that has been on the shelf for a few months, and I''m picking it back up. I''ve frozen Rails at 1.1.4 in vendor/, and did the "rails ." and "rake rails:update" to get it up to a current Rails level. The code initially seems to be working fine, but when I go to my login method, I get a 500 error thrown. Looking in the

I noticed a lot of repetition across different Sweeper models in my app expiring the same fragments and so have been trying to move all the expire_fragment calls into another model which the sweepers can then use but it''s not working as I''d hoped.. I''ve created a CacheDestroyer model and want to be able to call something to the effect of:

Hello all. I am having a hell of a problem and it''s driving me nuts. I get the following error (undefined method `controller_name'' for nil:NilClass): but only when config.action_controller.perform_caching = true I googled around some and found this thread http://groups.google.com/group/communityengine/browse_thread/thread/b84154e5228bf9f3which suggests it may be a conflict with

[cross-posting to rails and typo lists] Hi, I''m tinkering with the code for typo, a rails-based blog engine. Typo has an XmlController with actions "rss" and "atom" which generate feed.xml files, and it uses a caches_page declaration to cache the files that get generated by those actions. It also has a Sweeper (Observer) class that expires those cached files when a

So I''m trying to follow along in Chad Fowler''s Rails Recipes (recipe #59, Keeping track of who did what) and I simply want to access the current user from within my cache sweeper. Normally you just reference @current_user but that doesn''t seem to be the case here. In Chad''s example, he calls controller.session[:user]. What''s the Authlogic equivalent?

posted this on Ruby forum, no luck there - maybe a Railser has dealt with this issue... I''ve made a rake task that I''m running from my rails, and it works - but only once. If I then restart the server (mongrel) it works again - once. I can simulate this in the console session as shown... q = Rake::Task["cache_sweeper"] => <Rake::Task cache_sweeper =>
