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 =

Hi All, A co-worker passed this info on to me: http://37signals.com/svn/archives2/google_web_accelerator_hey_not_so_fast_an_alert_for_web_app_designers.php The Skinny: Google has a "Web Accelerator" that pre-caches pages by following url''s. If you have any plain/simple URL''s that don''t take paramaters (like what often happens in rails apps), it will try to

Hi all, Sorry if I should be posting this elsewhere--I couldn''t find an Instiki specific mailing list, but the Instiki site is down. I wanted to mention that my friend Tim Lauer and I are going to be doing a short "high order bit" talk at the O''Reilly Emerging Technologies conference, describing a particular use of Instiki which we came up with:

hi, how can i override rails errors mesages (that are in english) to display them in an other language? thanks hangon

Hullo, fellow Railsers! (warning: this isn''t a 100% Rails specific question, but I guess it very much applies to what a lot of us are currently doing.) For a project that involves messageboard functionality I''m looking for a good way of sanitizing user input, so the silly fools, err, my wonderful users don''t mess things up too much. I''ve played around with

One problem I sort of always had with the ActiveRecord''s tight coupling to the SQL backend is how slow it makes the unit tests. OK, there are some ways to make it faster at a price of extra complexity (reusing the fixtures, doing a rollback in the end of the test, etc), but still - it is much slower than what I would like a unit test to be. Today I had a very simple idea (why, oh why

This problem has been discussed a number of times, but none of the given solutions seems to work for me. Problem: Trying to generate the infrastructure for testing with Cucumber gives the following error ~/.../OTK-register$ rails generate cucumber:install /home/tpollak/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:251:in

Hi, I have this scenario. I have the full path of a page stored in the database (column ''path''). I want to be able to have very short urls for retrieving the pages, so i have this route in my map map.connect ''-/:title'', :controller => ''page'', :action => ''view_by_title'', :title => nil so when I go to

Hi guys, After a few days of webrick seeming to use up a ton of ram (the longer it was running, the more ram); izayoi on #rubyonrails kindly suggested changing Dependencies.mechanism in development.rb to :require which appears to have fixed the prob - at the expense of having to restart webrick after making changes to .rb files. Is this a known issue, or is there an alternative solution?

but the model isn''t the right place to send mail from. That just seems like pretty bad coupling, generating emails from within the model. Or is that not a problem? On top of that, these emails need to contain links back to my site...which is a bit of a pain in ActionMailer, but I found directions on http://wiki.rubyonrails.com/rails/pages/HowtoUseUrlHelpersWithActionMailer however I

Dear all, If you thought Instiki was a dead project, you were right. Since I''ve got a day job that doesn''t suck (Official Ruby Zealot of ThoughtWorks Canada), my motivation to do open source greatly sufferred :) But... but... but! Here is Instiki 0.11.0, and in this version Instiki is (finally!) moving to ActiveRecord backend and (finally!) has the File Upload feature.

hello, is the instiki project still being developed? it seems the web site is down for a couple of weeks now, and almost no activity is going on on the developer mailing list. on a related note, are you aware of other actively developed rails-based wikis? many thanks in advance.

I am trying to do a tutorial improvement on the wiki but I am having some problems with the auto formatting. Using httdp.conf produces http://httpd.conf when filtered. Using *.so produces .so and bold text there after. Is there any shorthand for the user for making text appear as it should without the linking and re-writes? Or does the admin have to change the filters in Instiki? Tesla

Hi all, Following the recent release of Instiki-AR beta, I haven''t had a lot of bug reports or other feedback. This could mean one of the two things. Either nobody is using it, or some people are, and have no problems at all. One thing for sure is that it''s certainly getting downloaded (20 times a day, as it were)! I''d like to know which way is it. So, if you are

Here''s a question for those well-versed in rforum or engines -- or both, ideally :) I''ve spent some time today turning RForum into an engine, using rails 1.0, engines trunk, and rforum 0.1 (as rforum trunk didn''t appear to work out of the box). My rforum engine works, but only when I do two things that I found by trial and error: 1) All rforum controllers subclass

(Donning flameproof suit) Am I the only person who thinks that the Ruby forum software sucks? E.g. search only for a word. Can''t search for new posts, can''t search by date, topic list doesn''t indicate when I''ve already read a post, there can be several independent replies to a topic, just to name a few. There are lots (admittedly not Ruby based) of good

Hi Guys, So creating a forums application seems like something that rails can handle easily and well, and whatever implementation that came to fruition would be head and shoulders above existing products like vBulliten and phpBB. Even the existing rails forums are using php-based forum products! An insult if you ask me. So my question -- is there any current development of a rails-based

Hi, I have installed InstantRails 1.0 Final on Win XP (Home SP2) and Win 2K 2000. I was able to get the two apps (cookbook, typo) work fine with Webrick but not with SCGI server. I tried changing the SCGI settings through the InstallRails.exe console so that the Runtime Mode: would be "development" instead of "production" and SCGI port: to 5000 instead of 9998.

Howdy - Someone''s probably already reported this, but anyhow, going here: http://wiki.rubyonrails.com/rails/show/RailsOnFedora results in: ==================== > Bad Gateway > The proxy server received an invalid response from an upstream server. > ==================== Yours, Tom

Camping now comes with a sessioning class, checked in tonight.
