Querying one to many with relation in rails?

Vote count:

0

I have two models set up like this:

class Page < ActiveRecord::Base
  belongs_to :book
end

class Book < ActiveRecord::Base
  has_many :pages
end

I know I can retrieve the book that a given Page belongs to if I have one model, e.g. page.book. But if I have an arbitrary set of pages, can I retrieve all of the books that all of my pages belong to?
