similar to: calling controller and caching from a sweeper class

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''

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/

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''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

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, 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

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 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 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 All, I have recently moved my PDC from a linux suse 7.0 box to a Solaris 8 server. I have downloaded the samba 2.2.8a and installed it without any errors. I used my old smb.conf and made the neccasry changes to it, I have pasted it below. I don't receive any errors, it just ends up using a local profile and doesn't bother to update it to the server. I have looked at countless

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 there, I'm trying to install the package RcppArmadillo in my R 2.11.1 which I installed and regularly update via Ubuntu's repositories.

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
