Documentation for scaffold / views
...r the view. I''d like to know exactly
what work is performed by the scaffold so that I can know this when
over-riding the view. (OR, is it that the controller makes these
variables available by default?..)
EXAMPLE: (drawn from Recipes tutorial)
Let''s start with this:
class CategoryController < ApplicationController
scaffold :category
end

following. What I''m trying to do is much more complicated but I think
this tiny example shows where I am stuck.
Into their browser a user types
"http://my.domain.com/admin/category/updates". I have a controller
roughly like the following
class Admin::CategoryController < ApplicationController
def updates
# a url for a get request that isn''t actually hard coded like this example
url = "/admin/category/info/1"
# the following line is the tricky one.
str = get(url)

scaffold suddenly pluralizing names
I haven''t updated rails today and all of a sudden scaffold is
pluralizing my names
ruby script/generate scaffold Admin::Category
produces
class Admin::CategoriesController < ApplicationController
Do I really want "CategoriesController" instead of "CategoryController"?
Thanks,
Peter

Nested Controllers
Hi there,
I wondered if anybody had any experience with having nested
controllers?For example, I''d like a hierarchy something like this:
/product
/product/list
/product/detail
/product/detail/category
I can''t find any documentation on this, so any advice/experience
anybody might have would prove useful.
N.B. This is for a generator which builds Views and Controllers
