similar to: Making 'expire_fragment' available to a model?

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

I''m just getting my hands dirty with caching. The pages I want to cache have some user specific data on them (for example "log out"). That sent me down the route of fragment caching. One of the things I want to pagination is a paginated list. My question is how is pagination and query strings handled with fragment caching? Does each page get its own fragment and query string

Hello all, We know that memcached or memcached-client doesn''t support regex... But It seems it doesn''t support expire_fragment either :/ I''m trying to use expire_fragment with memcached as following : expire_fragment(:controller => ''home'', :action => :list_posts) But apparently it''s not supported by memcached : RuntimeError (Not

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

I am trying to figure out a way to call the expire_fragment outside of a controller. I need to expire some fragments on a hourly basis. I have a Thread that every hour that will perform a task. The expire_fragment is located in the module ActionController::Caching::Fragments as an instance method. Do I need to mixin the model ActionController::Caching::Fragments into my class? Or is there

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

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/.

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

I''ve seen a couple of workarounds on the mailing list related to expiring cached fragments inside of models, but nothing too clean. Anybody have any suggestions for handling this at the model-level? I have an application is updated outside of the Rails controllers, so I can''t use a Sweeper. The 2 methods I''ve seen: a. Use a callback to generate an HTTP post on a

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/

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''

Hello, I am trying to expire fragments (or at least trigger their expiration) from a daemon that''s running in the background. The daemon is updating all kinds of important lists every few minutes from the background. So I have to find some way to DO or TRIGGER the fragment caching from this daemon. Unfortunately just using the normal commands like: expire_fragment :controller =>

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 website that has a very slow loading frontpage. I wanted to start by caching certain elements that have high load. For example, it loads the last 50 comments, along with the corresponding usernames, avatars and more. So I cached that fragment and created a sweeper that observes Comment and expires after every create or destroy action. However, I have two problems:

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

I''ve just pushed out a new bug-fix release for the Engines plugin. Most notably, it''s now super careful (to the point of paranoia) about ensuring that the right version of Rails is loaded, and should no longer cause any issues where it ignores vendor/rails. Full CHANGELOG is here: http://dev.rails-engines.org/repository/file/engines/tags/rel_1.1.2/CHANGELOG And you can find

Hello, I am trying to invalidate a cached fragment. My fragment looks like <% cache ( :controller=>''users'',:action=>''additem_to_cart'',:action_suffix=>@user.id) %> At this point,rails has created 2 cache files correctly and everything works fine becuase I dont see rails making calls to the SQL db to get items from DB.Instead it uses cache.

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
