Simple dropdown menu
Hi, I''m quite new to this language and I''m having trouble finding out
simple things like a dropdown menu in rhtml. I know I have to use <%
select_tag %> but I''ve read lots of different ways to put in the options
so I''m a bit confused. Options are hard-coded for the menu I''m trying to
create so no database is involved!
Thanks v much!

db:migrate question
Hi,
In my environment.rb, I have set:
config.active_record.schema_format = :ruby
Whenever I do a rake db:migrate, both db/development_structure.sql and
db/schema.rb get generated. This shouldn''t happen should it? I thought
I should only get db/schema.rb?
Thanks,

$_SERVER for rails?
Is there something similar for rails that is like $_SERVER in PHP?
Something that gives you the hostname, etc. I tried using just host in
my controller, because the documentation says there is a host method,
and got an undefined method error.

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.
def search(params)
Ad.find(:all) do

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
completes
