Browsing nested models

Rails
1

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: (index.html.erb · GitHub)

Listing people

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

<% ent.branches.each do |branch| %>









<% 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 %>

<% end %>

<% end %>
<% end %>

<%= ent.name %>
<%= branch.name %> (<%= branch.people.count
%>)</
th>
First name Last name Sex Age Email

<%= link_to ‘New person’, new_person_path %>
