similar to: Caching problem: expire_page not working

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

I''m having a bear of a time getting my cached pages to expire. Maybe one of you guys can help me out. I''ll show my sweeper and then my log to show that it "should" be working. class PragmaticSweeper < ActionController::Caching::Sweeper observe Comment def after_save(comment) expire_page(comment.post_id) end private def expire_page(post_id)

Hi, I''m trying to use sweepers for the first time and got a problem - I get "undefined method `merge'' for "/signature/ f2d7c7c66450b169.html":String". The "/signature/f2d7c7c66450b169.html" part of the error message is the cached page. Here''s my sweeper: class FooSweeper < ActionController::Caching::Sweeper observe Foo def

[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

I''ve just set up caching on my site and want to expire some of fragments on an hourly basis. I was going to use cron and script/runner to do this. For other fragments that I am expiring, I am using expire_fragment inside a sweeper class, something like: class QuestionSweeper < ActionController::Caching::Sweeper observe Question def after_validation_on_update(question)

I''m trying to use the following methods (extract): expire_page :controller => "site", :action => "funding" cache_page :controller => "site", :action => "welcome" to rebuild my entire site cache from an admin page, but I can''t seem to get the cache_page function to work. looking at the docs there seem to be 2 versions of

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 all - I was wondering if there''s a plugin out there that will make expire_page work across multiple servers? That is, I''ve got two servers A and B behind a load balancer. If I cache a page eventually it will be cached on both servers. I''d like a way to expire that page and have it happen on both servers. Perhaps some integration with backgrounddrb that could

Problem: 1. ERB and Builder template engines are heavily wired in ActionView::Base 2. Should be optional. If we use different engine - why load all their stuff if not needed? 3. There are template engines which expect files in their own locations and cache them in their own way. For instance a template engine may store templates in a database. These engines don''t need any central source

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/

In the site I''m building, my models are *almost* never updated within ActionController-- all new data comes in via command line scripts manipulating ActiveRecord directly. Can anyone offer any hints about expiring cached actions without Sweeper? -Ross

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''

I''ve got caching mostly working but it''s acting string with the index/home. On the site I have a redirect the points http://nutritionreality.com at http://nutritionreality.com/home I do this in routes.rb by: map.index '''', :controller => ''home'', :action => ''index'' Caching happens on index (index.html gets created in

Hi Everyone, Just thought I''d post some details of an interesting little quirk I''ve found with page caching. For a site I''ve just built for a small music festival, there are a number of artist profiles. I''m storing the artists in my database, but using caches_page to speed things up when displaying the details to the public. I''ve also made it so

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:

Hi folks - Seeing a weird problem and would love some help. It''s documented in http://pastie.org/278310 to be more readable. In short, I have a caches_page "action", :if => {stuff} but the :if is never being called - the action is just caching every time. (If I put a debugger call in the :if block, it never stops.) If I replace caches_page with caches_action, the if

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

Hi I''m working on a program which relies on heavy cache sweeper usage. I''ve just bumped onto an odd problem. When using render_component method in layouts or templates with cache sweeping turned on, Rails throws an exception with the following message: NoMethodError in TestController#index You have a nil object when you didn''t expect it! The error occured while

For example - i have a sweeper for one model(in this case About). class AboutSweeper < ActionController::Caching::Sweeper observe About def after_create(data) expire_about(data) end def after_save(data) expire_about(data) end def after_destroy(data) expire_about(data) end def expire_about(data) FileUtils.rm_rf
