similar to: A bug in sweeper.rb? [was: A frustrating and strange error when config.action_controller.perform_caching = true]

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

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

Hi, I''ve got a table with an inserted_at column. When I insert a record it automatically injects the current date/time, all is well. Then when I insert a second record, it uses the exact same timestamp that is used in the first record. This behavior only seems to occur in production mode. When I restart the server, the problem goes away but then immidetatly occurs again on the

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

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

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

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''

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?

[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 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

For some reason, in production, with this one line of code: javascript_include_tag :all, :cache => true I get this: <script cached="true" src="/javascripts/prototype.js?1193454472" type="text/javascript"></script> <script cached="true" src="/javascripts/effects.js?1193454472" type="text/javascript"></script>

I''m working on an ecommerce site (in Rails 2.3) and I added: ActionController::Base.session_options[:secure] = true to ~/config/environments/production.rb Now, every time I add something to my shopping cart and navigate away I get a new session_id (which essentially empties my shopping cart). How can I get the continuity of my sessions back, while still having the session_id get set

Hi, i just wanted to say my sorries in advance (sorrie/sorry/sorri)...i have just started learning about the subject of caching, but unfortunately haven''t effictively managed to implement what i had learned. obviously it''s possible to cache a whole page, or action with the caches_page :x or caches_action :y methods, but for some reason it hasn''t really worked with

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/

Last time i ask the same question here that if one article item has a default icon in front of its title,the icon will be downloaded as many times as the article items displayed in one page in IE. I was suggested to modify some options under development enviroment,eg: config.cache_classes and config.action_controller.perform_caching in development.rb are both set to true.But the problem still

Hi, I created some new models that do not extend ActiveRecord::Base. For some reason, these classes are being cached in development mode. Controllers are not cached, neither are models extending ActiveRecord::Base. Has anyone else seen this? Here are my relevant development.rb settings: Dependencies.mechanism = :load

I am a complete beginner to Ruby. I followed the tutorial to create my own scaffold called Books. My problem is that, when I make changes to its index.html.erb, the http://url/books page does not update for a few minutes. I am using a development environment, and the config.action_controller.perform_caching value is already set to false. Any help would be appreciated!
