uniqueness validation perplexity
I want to write a validate routine to check to enforce that a position
must be unique in a category. (In another category, it doesn''t have
to and shouldn''t need to be unique.) I write this code which works
happily for new items:
def position_in_category_not_unique
@items = Item.find( :all, :conditions => [ "category_id = ? AND
position = ?", category_id,

nOOb question: How to use find_all with form input data
Hello,
I''m having a problem utilizing the find_all method with a value from a
form. I keep getting the following error:
Mysql::Error: #42S22Unknown column ''category_id11'' in ''where clause'':

Calling ActionView from uninheriting class
Hi Gurus, I have a class, specified in models cart.rb, which doesn''t
inherit from anything--it''s just a container

I just discovered I can''t call number_to_currency in that class. Any
idea how to "include" it in my code? I tried
ActionView.number_to_currency without luck. I could kill a few lines

validates_presence_of *_id attributes
Hi all,
I am a newbie to Rails. Please enlighten me on how to do this
appropriately, the Rails and the Ruby way:
Suppose I have a Recipe model. Let''s simplify things and pretend that
it has only 2 attributes, a :name and the other is a ''category_id''. In
the recipes table, category_id is a foreign key to field id of table
categories.
We also assume that I have generate

missing foreign key fields in scaffold views
Is there any reason that foreign key fields do not show in any of the
scaffold views ?
project table:
id serial primary key,
category_id integer,
user_id integer,
name varchar,
morestuff varchar
foreign key (category_id) references categories(id),
foreign key (user_id) references users(id)
scaffold generated views only show name, morestuff fields

why belongs_to does not like validation?
This works :
class Recipe < ActiveRecord::Base
belongs_to :category
end
But (when I add validation) this does not work :
class Recipe < ActiveRecord::Base
belongs_to :category
validates_length_of :category, :within => 6..20
validates_uniqueness_of :category, :message => "already exists"
end
thank you

More elegant solution for "missing" has-many through ids?
I have LabGroup and LabDesc which have many through LabDescGroup. I''d
like to identify LabDescs which don''t have a LabGroup. This works:
x = []
LabDescGroup.find( :all, :select => ''DISTINCT lab_desc_id'' ).each{ |c|
x << c.lab_desc_id }
y = []
LabDesc.find( :all, :select => ''id'' ).each{ |c| y << c.id }
notfound = x - y

AJAX - how to have multiple select form sets implemented?
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.
Now, let''s assume that a given blog can have multiple categories (and
subcategories).

Page does not seem to be reloaded on prod server
Hi all
I''ve coded a small shop that works well on my dev machine (OSX 10.5).
But look at the following page:

When clicking "Reservieren", the page is forwarded to a new page, where
the product is added to the shopping cart, and a flash notice is
prepare. Then the page is redirected back to the shop page.
