Rails 3 telling me route doesn't exist

Rails
1

– 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

<%= link_to "See all Categories", categories_path %> <%= button_to "delete this Category", category_path(@category), :confirm => "Are you sure?", :method => :delete %>

Category: <%= @category.name %>

<% @category.subcategories.each do |category| %> <% end %>
Sub Category Name  
<%= category.name %>  
<%= link_to "Create a new Sub Category", new_category_subcategory(@category) %>

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>

Does “rake routes” show anything helpful?
