Weird problem related I am having with scaffold
i,
I have this in expense_controller.rb:
class ExpenseController < ApplicationController
scaffold :expense
end
It works fine, but let''s say I want to override scaffold''s list.
For some reason, just making list.rhtml in views\expense is enough, and
there''s no need to add
def list
end
in expense_controller.rb. However, that''s not my real problem.

work and I keep running into this strange problem. I am setting up the

newbie: OSX Ruby/MySQL issue?
I''m three pages into the OnLamp RoR Tutorial [1] and am wrestling
with what appears to be a MySQL connection problem.
I''ve created a simple controller called "recipe" with a corresponding
"recipes" mysql table. The recipe controller is just a simple scaffold.
When I browse to "recipe/new", though, I get these errors:

Newbie question: scaffold not working
I went through a tutorial at

In Rolling with Ruby on Rails tutorial -
http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html - I saw that to
introduce a new element to my domain, I needed to define it in a table,
generate a model element with a similar name and the class would
autoamtically take the attributes from the table definition. Is it
possible to do this in the other direction... i.e to take the class

Customize list.rhtml to display only certain db columns
Hi,
Very new to RoR; have been a flash developer for four years or so. I
have an urgent question -- in the list.rhtml file, I only want to
display certain columns instead of dumping out all the columns in the
