What I want to do is click on a post and display all the categories that the post is in. class Post < ActiveRecord::Base has_many :categories end class Category < ActiveRecord::Base belongs_to :post end ...simple enough. In the categories_controller I have this: def list_all_categories

Is there a way to add per-field analyzer? I can''t seem to find a way to do that. Thanks -- Kent --- http://www.datanoise.com

Lucene''s standard analyzer splits words separater with underscores. Ferret doesn''t do this. For example, if I create an index with only document ''test_case'' and search for ''case'' it doesn''t find anything. Lucene on the other hand finds it.

Hi,   I'm new to R and S4 classes. I defined a class with two methods (myMethod1 and myMethod2). I want to call myMethod1 within myMethod2. Why does the code below not work?

Dear useRs and wizaRds, I am currently developing a set of functions using S4 classes. On the way I encountered the problem exemplified with the code below. For some reason the 'validity' method does not seem to work, i.e. does not check for errors in the specification of the slots of the defined class. Any hints? My understanding of the whole S4 system was that validity checks are made

Greetings, I tried upgrading Rails to 1.1.2 and now nothing is really working. In connection to the Rails upgrade I upgraded my Ruby version to 1.9.0. I also upgraded all my gem installs. Since my old rails apps stopped working I tried generating a fresh one , alas with the same result. Below I included the full trace when trying to reach the app. Line 3 in application.rb is : class

I''m trying to figure out how to use modules with my model classes. I''m going to have good number of model classes that don''t map to the database, and I''d like to put some of these in seperate modules. I''ve been wrestling with this for 2 days and can''t figure out how to get it to work. Rails seems to handle it fine for controllers, though. I

Hi Accesses the $new method for a class defined in a package fails if the methods package is not loaded. I have created a test package with the following single code file: newTest <- function() { cl <- get("someClass") cl$new } someClass <- setRefClass("someClass") (This is similar to code actually used in the testthat package.) If methods is not loaded,

Hello Everyone, I''m pleasant to announce the release of ruby-debug 0.1.3.

Hi, I think there is still a major vulnerability exists in the latest Rails 1.1.5. The problem is in the routing.rb file and safe_load_paths method. Because of the erroneous regexp it is possible to perform a DOS attack on any rails application. To reproduce: 1. start your application 2. use this url: http://localhost:3000/debug Routing module will load standard debug.rb script which stops a

Hello. I hope this is the right place to describe my problem ? After upgrading to Rails version 1.1.2 from rails version 1.0.0, Web Service functional tests seem broken. I upgraded rails (as the root user / administrator) with: # gem update rails --include-dependencies then I upgraded my application (as myself) with: ? rake rails:update % rake rails:update:configs After these steps,

Hi, I''m interested in using a currency conversion web service in my rails app. Does anyone have a free service that they use and like?
