similar to: cache_sweeper

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 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:

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 created a sweeper ItemSweeper and saved it in app/models/item_sweeper.rb. Then I put this in my item_controller.rb: cache_sweeper :item_sweeper, :only => [:create, :destroy, :update] But now when I call the view action, I get this error: ActionView::TemplateError (undefined method `title'' for nil:NilClass) on line #5 of app/views/item/view.rhtml: 5: <H1

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''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

In the Rails Recipes book the recipe "Keeping track of who did what" explains how to do decoupled observing of models. In my application I''d like to do a similar thing but watching the controllers. For example, when somebody hits the login method of the Security controller, I''d like to make a note of it. In this case I could observe the User model and watch for

I''ve enabled page caching on a site I''m currently constructing. The sweeper is called upon any changes made to the model, as expected. The sweeper code is as follows: class PersonSweeper < ActionController::Caching::Sweeper observe Person def after_update(person) expire_staff_page end def after_destroy(person) expire_staff_page end def

I''m having an issue with flashing divs in IE (firefox is fine and the only other browser I''ve used) My scenario is as follows. I have 2 divs (initially hidden) and using the BlindDown and BlindUp functions (possibly others) the divs flash when starting to roll down in BlindDown (due to the Element.show call) and also at the end of the BlindUp call (due to the Element.hide call)

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

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 =>

Hello, I''m having a problem when I set the tree option to true on Sortable. If I set the option to false my remote call works fine, but once I set it to true, I get some weird log errors from Webrick... undefined method `update'' for "11":String /usr/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/cgi_ext/cgi_methods.rb:214:in `build_deep_hash''

Hello, I posted this to the main rails list (http://www.ruby-forum.com/topic/99845), but haven''t received any replies yet, so maybe this question is better suited here. Sorry if this has been brought up before, I couldn''t find any previous discussion on this. To summarize the post... When using the latest Rails (1.2.2) I''m passing an array to url_for like so...

I have a library I''ve developed that I believe is the most flexible and useful table sorting/striping/row-selecting library around. Big features: Single and multiple-level sort Arbitrary sort criteria (IP address, date, etc.) Works with table headers that are > 1 row or column large Stripe tables and/or enable row selecting Row selecting supports drag-select and SHIFT-click No extra

Hello all, Not a directly related question to scriptaculous or prototype, but I am looking for a good, dynamic vertical javascript menu. I''ve done some searching and there are a lot of menu implementations out there. I''m looking for something more or less free, but will pay/donate a small fee towards something worth while. I figured I''d ask here to help filter down

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 everyone, I just submitted a patch for a new fieldset_tag helper.

Why do effects that display an element (like Appear or Slide Down) start by displaying the element for a split second and then make the element disappear? _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails-spinoffs

hi all, I''ve built a simple javascript datepicker for use with Rails. I''m sure others exist, but think this one is quite decent without being overengineered. http://projects.exactlyoneturtle.com/date_picker/ At present there''s no Rails HTML generator method for it; later I will package it in a script/generator, but for now it is quite easy to use with Rails and

I want to run a single filter in my application.rb file, and then if a certain condition is true, end the action''s processing immediately. Right now I''m using prepend_before_filter to ensure that it gets run first, but some of my around_filters are still being processed. Is there a way that I can clear out all the filters that should be run? Basically it''ll look
