cache sweeper not getting called
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

Making 'expire_fragment' available to a model?
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: CacheDestroyer.clear_all_page_relations but I''m struggling to find how to make the "expire_fragment" method ava...

Problems when using sweepers with postbacks
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

cache_sweeper
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

"Undefined method merge" when using sweeper

Ajax, the Back button, and Sweepers
...e 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 the server when the visitor uses the Back button. Anybody got any experience with Sweepers they''d be willing to share? Thanks in advance, Bill -------------- next part -------------- An HTML attachment was scrubbed...

Caching::Sweeper Access to Controller
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.

Easy question: Where do I put sweepers?

Are cache sweepers used?
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/

trouble expiring cached pages
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)

calling controller and caching from a sweeper class
[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

Cache Sweepers and runner scripts that act on models?
...oy/update on Item, and it works fine when accessing controllers via the web server, but apparently doesn''t work via runner. Controllers have a ''cache_sweeper'' class method, but ActiveRecords don''t (though they do have observer and filter methods, which is what sweepers are a combination of). How can I get the cache sweeper to do its job when adding items via a runner script? Am I supposed to call controller methods instead? And if so, how? (I tried, but got a ''uninitialized constant ApplicationController'' error.) thanks for any help! csn -...

Samba PDC not creating roaming profiles
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

"value must be enumerable" exception when using a sweeper?
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

Authlogic::How to access current user from within a cache sweeper?
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?

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

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