Ruby on Rails: Display relationship between 2 models - ruby-on-rails

Question

I have an authors page that displays all the authors in the database.
<h1>Listing authors</h1>
<table>
<tr>
<th>Name</th>
<th></th>
<th></th>
<th></th>
</tr>
<% #authors.each do |author| %>
<tr>
<td><%= author.name %></td>
<td><%= link_to 'Show', author %></td>
<td><%= link_to 'Edit', edit_author_path(author) %></td>
<td><%= link_to 'Destroy', author, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</table>
<%= link_to 'New Author', new_author_path %>
And for each author, you click show, to bring up their own page.
<p>
<b>Name:</b>
<%= #author.name %>
</p>
<%= link_to 'Edit', edit_author_path(#author) %> |
<%= link_to 'Back', authors_path %>
Now I have the same set up for books, where the user can enter new books, show and edit books in the database.
I then set up a model called authorbooks that holds a relation ship between authors and books using has_many, and belongs_to in the models for author.rb, book.rb and authorbook.rb.
I am wanting the show page of the author to display every book that they are related to.
How would I go about this? I am new to rails and still learning so please remember when answering. Thanks in advance.
EDIT model code for each model:
author.rb
class Author < ActiveRecord::Base
attr_accessible :name
validates :name, :presence => true
has_many :authorbooks
has_many :books, :through => :authorbooks
end
book.rb
class Book < ActiveRecord::Base
attr_accessible :name
validates :name, :presence => true
has_many :authorbooks
has_many :authors, :through => :authorbooks
end
authorbook.rb
class Authorbook < ActiveRecord::Base
attr_accessible :author_id, :book_id
belongs_to :book
belongs_to :author
end

Answer 1

It would have been interesting to see the model code as well. I assume you have something like:
class Author
has_many :author_books
has_many :books, :through => :author_books # this line might be missing,
# read in the api documentation about it.
class AuthorBooks
belongs_to :author
belongs_to :book
Now you can do something like:
<h3>Related books</h3>
<ul>
<% #author.books.each do |book| %>
<li><%= book.name %> <%= link_to "Details", book_path(book) %></li>
<% end %>
</ul>
Without the :through line you could have done something like:
#author.author_books.each do |ab|
... ab.book.name ...
Note 1: you get N+1 load problems with the second example. See the eager loading chapter in A::R guide for more information about that.
Note 2: Checkout HAML; much nicer than ERB
