No, book is a class, I assume at least.
Probably in your models directory you have a book.rb file that has
class Book < ActiveRecord::Base
<stuff>
end
-> Then, show in the view: All "Number of pages": <%= @books.collect

You probably want a column called number_of_pages in your books table
Then you can do:
book.number_of_pages = 123
book.number_of_pages #=> 123
Hope that helps
