hi, there :) Consider a blogging application whereby a user is trying to add a new blog. He/she has to select a category. Upon selecting a category from a drop down box, a new sub categories drop down box will be created (hence an AJAX call). Got this implemented and it''s ok.

I''m writing a simple CMS where every item ("listing") HABTM categories and subcategories (which themselves belong_to a category).

Hi all, (I''m new with RoR) I''m using a migratio to import data into a database but nothing is being happens. I''m importing strings from a parsed file. this is what I have: controller: class UploadController < ApplicationController def create table = { } params[:localized_string][:data].each_line do |line| if line =~ /^\s* " (.*?) "

Is there any particular distro that seems to be most used among RoR developers on Linux? Any that might provide better support somehow for development of RoR apps? -- Posted via http://www.ruby-forum.com/.
