Asp Forum - How do I access a my :include data in my Ruby SQL results

I am new to Ruby on Rails, so this is probably a very easy answer:

Two tables -- one of authors, one of books
authors belong_to books
In my situation, each book can only have one author.

I want to list all the books (with the author name) in a Select field.

@all_books = Book.find( :all, :include => [:authors] )

Then, I create the Select statement:

select(:book, :id, @all_books.collect {|b| [b.book_name + " (" +
b.author_name + ")", b.id ] }) %>

This creates an error because I'm trying to include the author_name.
When I run @all_books.inspect, I can see the author info in there.

So, how do I actually access the author data from that array (or object,
or whatever the correct terminology is)?

Thanks!

Rails (the web framework) is not the same as Ruby (the programming
language). So you would do much better to ask your question on a Rails
mailing list or forum. They are linked from rubyonrails.org

Agreed that it is better to use the Rails list/group. But you probably
want b.author.author_name.
