Becca,
It looks like you're on the right track, but you might want to
familiarize yourself with nested resources/routes in Ruby on Rails.
You shouldn't need to specify the type/id as hidden fields like this.
In your routes, you can do something like:
map.resources :books, :has_many => [ ::reviews ]
Then where you want to show the review form, you could do something like...
<% form_for :book, :url => book_reviews_path( @book ) do |f| %>
When the form submits, you should see the book_id in the params hash,
which you can use to connect the dots.
Good luck!
Cheers,
Robby
