Create a hyphen-separated set of letters derived from a string - How to?
Hi,
This is such a trivial programming issue, but I can''t find a way to
transform, say ''abc'' to ''a-b-c'' without using pattern matching.
Any ideas?
Thanks in Advance,

Switching the version of Rails that an app uses
Hi All,
I’ve got a few versions or Rails installed and I''d like to run an App
I’m developing with various versions of Rails. I heard of two ways to
switch the version of Rails that an app uses:
1. Use GitHub as described by http://kylecordes.com/2008/04/30/git-windows-go/
. But that requires using Bash in a Command Window and more steps
than I want to go through.
2. Alter

Added associations but don't see generated methods
Hi,
I''ve got a Rails app working that includes two two classes, etc.:
Expense & Vendor. I eventually learned that the mental concept I had
of their relationship should be express in Rails as:
class Expense < ActiveRecord::Base; belongs_to :vendor; end
class Vendor < ActiveRecord::Base; has_many :expenses; end

Conditionally adding a link to a form -- how?
I''ve got two entities created by scaffolding: Expense & Vendor
In Expense#new there''s a form with a Vendors-drop-down and a NewVendor-
button.
The latter button brings up Vendor#new.
The Create button in Vendor#new brings up Vendor#show with Edit & Back
links.
I want to append a third link conditionally to Vendor#show: if the
Expense#new form led to the Vendor#show

How to find/open Spec::Expectations and Spec::Matchers
Hi,
Then RSpec 1.4 recommends, in the webpage http://rspec.info/documentation/expectations.html,
referencing the subject items.
I''m running ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32] over
WinXP-Pro/SP2.
I believe I installed RSpec with a Ruby gem. At least, I think that''s
confirmed because I have a lot of stuff in the directory K:\_Utilities

Specifying a decimal field precision/scale with scaffold requires 2 steps?
Hi,
It appears to me that the command:
ruby script/generate scaffold whatever money_field:decimal(10,2)
will not generate a valid migration.
Therefore it appears to me only two ways to achieve the desired result
is:
1.1 Omit the the precision/scale on the scaffold command
1.2 Edit the migration file by following the "do |t| ... end" with
the command:
change_column :whatever

"We're sorry, but something went wrong." from RoR app
Hi All,
"We''re sorry, but something went wrong." is the message I got when I
started up an RoR app in the environment:
Rails 2.3.5
Ruby 1.8.6
WinXP-Pro/SP3
Firefox 3.6
MySQL 5.0.37-community-nt
Mongrel
The app under development was working fine until I (stupidly) thought
I needed to upgrade MySQL to 5.1.44.
I took the precaution of MySQL-dumping
the development db before
