Maybe you have to use @record.author.id, probably ActiveRecord don't set
author_id when you set author association until save the record, which is not
done on render_field. What is the sql issued when book field is refreshed?

If author is an association, that line does nothing. In other case it's wrong,
it won't work in production mode, because you are fixing options to authors
available at application startup. In development mode it works because classes
are loaded for each request. You should use a per-request configuration with a
before filter, or better, a form override (helper method).

Same comment as above, book and author options are wrong.
