Browsing nested models

Hi all,

Beginner's question here: I've wondered, why I can't browse through "nested" models (belongs_to/has_many).

My models: (http://gist.github.com/291956)

class Enterprise < ActiveRecord::Base     has_many :branches     has_many :people, :through => :branches end

class Branch < ActiveRecord::Base     has_many :people     belongs_to :enterprise end

class Person < ActiveRecord::Base   belongs_to :branch, :include => :enterprise end

And finally viewing people: (http://gist.github.com/291953)

<h1>Listing people</h1>

<table>

<% @enterprises.each do |ent| %>

  <tr>       <th colspan="8"><%= ent.name %></th>   </tr>

  <% ent.branches.each do |branch| %>       <tr>         <th colspan="8"><%= branch.name %> (<%= branch.people.count %>)</

    </tr>     <tr>       <th>First name</th>       <th>Last name</th>       <th>Sex</th>       <th>Age</th>       <th>Email</th>       </tr>

    <% branch.people.each do |person| %>     <tr>         <td><%=h person.first_name %></td>         <td><%=h person.last_name %></td>         <td><%=h person.sex %></td>         <td><%=h person.age %></td>         <td><%=h person.email %></td>         <td><%= link_to 'Show', person %></td>         <td><%= link_to 'Edit', edit_person_path(person) %></td>         <td><%= link_to 'Destroy', person, :confirm => 'Are you sure?', :method => :delete %></td>       </tr>     <% end %>

  <% end %> <% end %> </table> <br />

<%= link_to 'New person', new_person_path %>
