Rails - Mar 2006 - select helper method

Hey

I''m having problems understanding the select helper. Here is my code:
_____________________
DB table: genres
id
name
descripition
___________________
In the controller:

    def index()
        @genres = Genre.find_all.map {|u|[u.name, u.id]}
        @id = params[''genre'']
    end
____________________
In the view:

<%
@genre = Genre.new
@genre.id = @id
%>

<%= start_form_tag :action => ''index'' %>
<%=select(:genre, :id, @genres)
%>
<%= submit_tag "show genre"%>
<%= end_form_tag %>
_____________________

What I''m trying to do is to select the option that was selected when
the
form was submitted back to the server..
The value I''m getting back in the controller after submit is
''id2''
whereas I would like to just get ''2''.
Is it possible?

@id = params[''genre''][''id''] is what you
want.

The idiomatic Rails way is however to move the creation of @genre
into the controller:
                       @genre = Genre.new( params[:genre] )

Thank you, works perfectly. Do you know where I might find more info on 
these kind of things? I have searched the net like crazy.

I also have the two official rails books.

The Depot tutorial and Chapter 14 of "Agile Web Development with
Rails"
(pragmaticprogrammer.com/titles/rails/) would be a good introduction.

Browsing the source of the Typo blog would also be instructive:
