Hello all, I am running a blog system which has its "/" (home page) cached like this: class ApplicationController < ActionController::Base before_filter :index_cache_expirer, :only => [:index] caches_action :index so the site''s top page is caches for 60 seconds in my case (index_cache_expirer is a home-made function to expire) on the site, there is also a multi-user /admin area, which in turn has its own controllers with :index action. The problem is that effect of "caches_action :ind...

I am trying to use caches_action and the agile book says that it is keyed off the URL, however it does not seem to pick up the URL parameters. http://localhost:3000/controller/action/id?foo=bar and http://localhost:3000/controller/action/id?foo=foobar Returns the same page. Anyone looked into how to add URL parameters to the ca...

...documented in http://pastie.org/278310 to be more readable. In short, I have a caches_page "action", :if => {stuff} but the :if is never being called - the action is just caching every time. (If I put a debugger call in the :if block, it never stops.) If I replace caches_page with caches_action, the if evaluates correctly. There are before_filters in the controller, but they do not apply to this action. (There''s one in the supercontroller but it seems similarly irrelevant - just trims www. from URLs.) What am I missing? Did I uncover an :if bug (which I doubt) or am I misunders...

Hello, I have a method called "check_permission" that is set to run as a before_fitler and which checks if a user has the authorization to view a page. This page is displayed through the method "show" which is cached through the tag "caches_action :show" My problem is that once a user with authorization to a page accesses it, then afterwards all users (with or without authorization) can access it. It seems that once the page is displayed once, then the before_filter''s result is cached and thus authorization is never checked...

Hi When I enable action caching in my controller with caches_action :view_thread only the first part of my layout template is rendered (up to the yield statement), and the development.log shows Processing ForumController#view_thread (for 127.0.0.1 at 2006-05-31 03:13:19) [GET] Session ID: d6f7ef15f479250fd7e31e252d70f5ff Parameters: {"action"=>...

...nted 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 what i had been doing. (i was trying to cache Time.now to no avail) either way, the issue at hand (not Time.now) is trying to cache an object that i will usually pull out of the database once per session...say i have a table...

...as the response gets sent out. Do i need to bookend each action with a before-filter and after-filter? Also, how could i track these numbers independent of caching? From my understanding, if i use rails caching, it will not go into the code if the page exists in the cache. I know that if i use caches_action, then the filters will be run, however, its important that i can log the times as close to the use as possible. I think this means either just before it hits dispatch.fcgi or just after. For certain actions i''d also like to log request information (referer urls, IP address, etc). Does th...

Today I had a strange behavior that made me suspect of jQuery at first, but then it happened that I''ve faced two gotchas, one from CoffeeScript and one from Rails itself. I have something like this: routes.rb post ''/fields/:id.:format'' => ''fields#show'', as: :field, constraints: {id: /\d+/} post ''/fields/remove/:id''

I have a system that requires login. This is for administrative purposes, so the pages will be the same as the public ones, except they will have the edit|delete|new options. Right now, I have: caches_action :index which works great, but I''d like: caches_action :index unless user? where user?() is defined in application.rb. I get an exception using this construct. Can anyone help? Thanks, Steve -- Posted via http://www.ruby-forum.com/.

Caching computation in rails? Simple example: factorial modulus a large number input: integer x output: factorial( x ) % 12345678901234567 I want it so that if it computes factorial of N once, it will not have to compute for N again. code: class SiteController < ApplicationController caches_action :factorial, :inv def examine @inv = @params[''inv''] @outv = factorial @inv.to_i end def factorial( inv ) y=1 while (inv > 0) do y*=inv inv-=1 end (y % 12345678901234567) end end I am running in production mode so caching should...

I have action caching setup for several actions of an application but I want the caching to only run for my administrators and have all other users see non-cached pages. Is there a way to do this? Perhaps something like passing a block to caches_action or setting some sort of flag in my authentication method? If this is not possible with action or fragment caching does anyone know of a plug in or other means to accomplish this sort of caching scheme?

...gt; ActionController::Base.fragment_cache_store => #<ActionController::Caching::Fragments::FileStore:0x8f81bac @cache_path="/www/apps/localfeeds/directory/tmp/fragmentcache/"> In a controller: class ExportController < ApplicationController before_filter :locale_finder caches_action :rss, :opml, :top10opml ... Yet tmp/fragmentcache/ remains empty (and removing the directory or making it unwritable produces no errors in production.log) I can tell by response times and watching production.log that it IS caching, so I can only assume it''s still using the default...

Hi , I have created a simple app which allows user logins and when user logs in a home page is shown which is built using some queries to the DB. I tried caching which didnt work properly because for some reason rails kep loading the old cache..Anyway What I was wondering is caching only avoids the render process but IMHO the queries are the most consuming. My code is something like def index

Is there a way to call or invoke a controller method from script/console or script/runner? The reason is that I''d like to pre-cache some of the actions on my controller. The pseudo code below is what I''d like to be able to do: class MyController < ApplicationController caches_action :test def test puts ''Hi there'' end end script/console: >> MyController.test => ''Hi there'' Thanks. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are su...

...e first problem, AR objects. Having a result set of 50k entries is obviously painful, and doing it with AR it will kill your instance, no questions asked. Worse, in my use case this result set can be asked frequently from the client. This however can be easily solved by using a sapient mixture of `caches_action`and `stale?`, although there may be few key issues when using memcached and friends, because especially in managed implementations, they may not support data keys larger than 1MB. Since instantiating AR objects it''s out of the question let''s focus and getting what we really want...

I''m noticing a different behavior between development and production environments when I use caches_action along with send_data. I have a method: def image @thePic = Picture.find(params[:id]) send_data(@thePic.image.data, :filename => @thePic.image.filename, :type => @thePic.image.content_type, :disposition => "attachment") end Which works fine; it returns an image as...
