similar to: cache sweeper not getting called

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

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 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

[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''m working on an app that''s basically forms and that makes fairly heavy use of Ajax. As a result of the Ajax usage, if the visitor uses the back button they get the page as it was originally loaded, not as they left it. I''ve looked at the Sweeper documentation and can not tell for sure that it''ll do what I want, which is to force an unconditional reload from

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

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/

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)

I''ve got a strange behaviour that didn''t seem to be happening before I upgraded to 1.2. I''ve got two models - questions and results. When a user answers a question, his answer is recorded in results. In my results model, I have an after_create that increments! a count in the question model. This increment is now triggering an after_update method I have in a

Trying to implement some sweepers to clean up my caching, but where do I put them? "ruby script/generate sweeeper" does nothing. -- Posted via http://www.ruby-forum.com/.

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:

How do I setup a sweeper to restart stale or hung mongrel servers? -- Jared Brown jaredbrown at gmail.com (765) 409-0875 7001 Central Ave Indianapolis, IN 46220 -------------- next part -------------- An HTML attachment was scrubbed...

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

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

First let me say that Rails caching is very very cool. The traffic (and responsiveness) I''ve saved by added 10 lines of ruby code would be enourmous, if I actually had traffic... ;) Sweepers as observers are great, btw. Since every page of my side is dynamic, once I did some DB optimization I''m caching the content of the index page which was taking the bulk of the time to load

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

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?

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.

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

Hi all, I''m new to rails and I''ve run in to a rather insidious bug. In development (with caching turned on in development.rb), my app successfully caches action "index" in controller "view": class ViewController < ApplicationController caches_page :index def index # do the stuff that index does end end I''ve got a sweeper
