I''m using this: <% words = article.content.split(/ /) %> <%= words[0..20] %> to (ostensibly) split a paragraph into component words, with spaces in between, then print to html only the first 20 items, words and spaces. I got this (split(/ /)) from the online pickaxe book at http://rubycentral.com/book/ref_c_string.html#String.split . The problem is, the resulting array

Hi guys. Total newbie here. I''ve been doing web stuff since 1996 but only began the foray into scripting last year. I haven''t got my skull completely 360 degrees around OOP yet. It''s just me here (in Japan) and there are no Ruby groups in my area (never mind any in English). I''ve got a database table - real simple: question, answer, and id fields - and I

I think I''m missing a step here, but they don''t seem to cover this in the AWDWR book... does anybody know the various steps required to switch from development to production mode in Rails?

I am furiously trying to find what I am looking for in Pickaxe book and not finding it. I''m getting some values back from a posted form and I need to get the ''id'' number off the backend. The ''String'' will always come back to me as... Some_name\r\n123 where 123 is actually the id number which I need to execute the find. The reason they are coming back

I''ve created a look-up table in my database that currently has 4 rows. I want to access these as constants in the application because that''s effectively what they are. I tried this... class StockRuleLevel < ActiveRecord::Base has_many :stock_rules SITE = find(:first, :conditions => "type_code = ''site''").id MAKE

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page.

I''ve been mostly lurking here with an occasional nuby question for a few weeks now. It seems like Ruby and Rails and the many libraries and tools growing up around it are a remarkable toolset. Unfortunately I''m finding the whole enchilada a bit daunting. It seems that if one is to truly tap into the power of this thing and do a significant amount of developing, one needs

I need to make a category browser that would allow nested categories. Is there any receipe on that? Currently, I use the :onchange event from one of the form element to update the first select (out of 4-5 selects), but I dont know how to elegantly reset all the child selects if I change the value from the first. All the categories are fetched from the DB and I would like a

Ahoy, I was able to follow the tutorials and build a simple to-do list program with Items and Categories and have the related tables link up w/ the default "scaffold :Items" command plus custom defenitions.

Hi everyone, I''m new to Rails and Ruby, and have been working my way through the Pickaxe and Agile Rails books for the last week or so. With a background in payroll apps I found that the default ActiveRecord mapping of decimal columns to float variables really bothered me! Financial calcs need high levels of accuracy and floats just don''t give you that. I know there are a bunch
