similar to: Rails fragment caching bug?

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

I''ve just set up caching on my site and want to expire some of fragments on an hourly basis. I was going to use cron and script/runner to do this. For other fragments that I am expiring, I am using expire_fragment inside a sweeper class, something like: class QuestionSweeper < ActionController::Caching::Sweeper observe Question def after_validation_on_update(question)

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:

Hi, I thought i''d give memcached a try. Installed it all, made the change in environment.rb and it all seems ok. I can telnet to memcached process and manually retrieve the data being cached. However, when I try to expire a fragment using a regex, eg: expire_fragment(%r{forums/recent/.*}) it throws an error: undefined method `delete_if'' for #<MemCache:0x2289968>

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

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. Now

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:

I''ve got a site that uses fragment cache stored in tmp/cache. When you access it as http://www.site.com it creates a folder tmp/cache/www.site.com. Likewise, when you access it http://site.com it creates af older tmp/cache/site.com I believe it does the same with sessions, though I store those in the DB. How do I go about fixing this? Can i redirect using .htaccess or Webmin? --

Hello, Quick question on caching based on time based expiration. Is this something that rails supports? Is there a way to instruct rails to refetch the new page after a time period or do we actually have to spawn a background process and have it expire the pages. Thanks, Sam. -- Posted via http://www.ruby-forum.com/.

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

Hi All, I''d like to use different caching strategies based on the visitor status - anonymous => action caching - logged in => fragment caching Is that doable? Where should I start?

I''ve written a plugin to allow for time based fragment caching. It lets you do things like: <% cache ''fragment_name'', 10.minutes.from_now do %> <p>something intensive which will be cached for 10 minutes</p> <% end %> Also, there''s a convenience method so that in your controllers you can do: when_fragment_expired

Hello. I wouldn''t mind getting some feedback about the use of fragment caching. I''ve got a series of relatively expensive database queries with their respective partials cached and everything is working fine. The problem is that do get this to work I''ve had to move the database queries from the controller into the view layer so as to avoid them being called if the

Hi, In my view I have the following cache: <%- cache(:controller => ''products'', :action => ''index'', :action_suffix => ''footer'') do -%> ... <%- end -%> And that''s the file generated: tmp/cache/views/www.mysite.com/products.action_suffix=footer.cache Why isn''t fragment caching picking up the :index

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 trying to setup some fragment caching which works fine for the index but i''m not sure how to ignore the caching if they are searching the index results. my code in short: ItemsController def index @items = Item.search(params[:search], params[:min_rank], params[:max_rank], params[:classification_id], ...) end index.html.erb <% cache (''items'',

Hello, I''m having problems on both my production and development servers with fragment caching. Every time I try to cache something using <% cache do %>, I get the following error: Couldn''t create cache directory: views/0.0.0.0:3000/jobs/106/questions/ 174 (wrong number of arguments (2 for 1)) but strangely, all of the directories apart from the last one are created.

From the API I was unable to determine if the new architecture for BackgrounDRB still handles fragment caching? If so, how can I use it? I am upgrading to the new architecture from the old one and used this functionality in the old code base. I like the new architecture, thank you. Cheers, Matt

Hi, with fragment caching one can cache parts of a page. However, more often than not what I would need is the exact opposite approach. I would like to be able to use action cashing and have a mechanism for telling Rails to exclude one or more areas from the cashing and fill them with dynamic content instead. A good example would be a page where all content would be perfectly cachable but one
