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

Shorter Rails 3 routes
Hi,
I have a small blog application, and I would like to shorten its routes.
Here they are:
Blog::Application.routes.draw do
resources :categories do
resources :articles do

Cookbook recipes eg - ordering categories in the recipe pull-down box
People,
I can order categories when looking at the categories list page but how
do I change the recipe page to list the categories in alpha order in the
recipe pull-down box?:
> <p><b>Category:</b><br>
> <select name="recipe[category_id]">
> <% @categories.each do |category| %>
> <option value="<%= category.id

Special ruby language for describing sql conditions
I was brainstorming today about a smooth way to define conditions in an
sql query, when the numbers of attributes increase, so does the uglyness.
So instead of passing a hash, I thought you could specify the conditions
directly in code.
I hacked together some example code which actually turned out to work.
The result is concise and pretty beutiful.

Building a conditions clause (for find) of multiple optional params?
I want to be able to find items according to various params - category_id, member_id, type_id,
rating, etc. What I have now is something like:
if(@params[''category_id''])
@items=Item.find(:all, :conditions=>["category_id=?", @params[''category_id''])

Doubt on composite index
The AWDwR book has the following:
add_index :categories_products, [:product_id, :category_id]
add_index :categories_products, :category_id
The first, composite index actually serves two purposes: it creates an index which can be searched
on both foreign key columns, and with most databases it also creates an
index that enables fast lookup by the product id. The second index then

render :partial + redirect_to :controller
This is of course disallowed, which I discovered only after nearly
completing my spanking new ajaxified UI. What is the motivation behind
this, and what is the best workaround?
This UI does a scriptaculous drag-and-drop of items from a first div
(div1) over to a second div (div2), which triggers the contents of div2
to be updated to reflect the drop. No prob, thus far. But then the

route with optional args?
Is it possible to specify a route like this:
/items(/category/:category_id)(/order/:order)(/page/:page)
and have any of the parts in parentheses be optional? I know I can make :category_id and the other
vars optional, but is it possible with the entire "/category/:category_id" part?
thanks

Undefined method
I really hope this is not a bad question (as in he''s abusing the

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

I''m working on a simple CMS. The main data type are "listings" a listing
