-- category.rb

class Category < ActiveRecord::Base   has_many :subcategories

  validates_presence_of :name   validates_uniqueness_of :name end

-- subcategory.rb

class Subcategory < ActiveRecord::Base   belongs_to :category end

-- categories_controller.rb

def show @category = Category.find_by_id(params[:id]) respond_with @category end

-- routes.rb

resources :categories do   resources :subcategories end

-- categories/show.html.erb

<div style="padding: 15px; background-color: #D8AEB5; width: 100%;">   <%= link_to "See all Categories", categories_path %>   <span style="float: right;">     <%= button_to "delete this Category", category_path(@category),         :confirm => "Are you sure?", :method => :delete %>   </span> </div>

<h1>Category: <%= @category.name %></h1> <div class="card">   <table id="sub_categories">     <tr>       <th>Sub Category Name</th>       <th>&nbsp;</th>     </tr>   <% @category.subcategories.each do |category| %>     <tr>       <td><%= category.name %></td>       <td>&nbsp;</td>     </tr>   <% end %>   </table> </div> <div id="default" style="background: none repeat scroll 0 0 #F9EDD8; padding: 5px; width: 98%">   <%= link_to "Create a new Sub Category", new_category_subcategory(@category) %> </div>

Here is the error I am getting. I've tried recreating this resource, re-doing the routes. Restarting mongrel. undefined method `new_category_subcategory' for #<#<Class:0x4a5ec34>:0x4a5d600>
