Ruby on Rails Show Nested ActiveResources - ruby-on-rails

Question

I have an app which connects to a REST rails app. I have two resources: category and post; post is nested in category.
I was able to successfully CRUD categories. I am only able to list posts but no success in showing or updating.
Here is my sample code:
config/routes.rb:
resources :categories do
resources :posts
end
resources :posts do
resources :comments
end
resources :comments
models/post.rb:
class Post < Connector
self.site += "/categories/:category_id"
end
controllers/posts_controller.rb:
class PostsController < ApplicationController
def index
#category = Category.find(params[:category_id])
#posts = Post.all(:params => {:category_id => #category.id})
respond_to do |format|
format.html
format.xml { render :xml => #posts }
end
end
def show
#category = Category.find(params[:category_id])
#post = Post.find(:id, :params => {:category_id => #category.id})
respond_to do |format|
format.html
format.xml { render :xml => #post }
end
end
end
rake routes:
category_posts GET /categories/:category_id/posts(.:format) {:action=>"index", :controller=>"posts"}
POST /categories/:category_id/posts(.:format) {:action=>"create", :controller=>"posts"}
new_category_post GET /categories/:category_id/posts/new(.:format) {:action=>"new", :controller=>"posts"}
edit_category_post GET /categories/:category_id/posts/:id/edit(.:format) {:action=>"edit", :controller=>"posts"}
category_post GET /categories/:category_id/posts/:id(.:format) {:action=>"show", :controller=>"posts"}
PUT /categories/:category_id/posts/:id(.:format) {:action=>"update", :controller=>"posts"}
DELETE /categories/:category_id/posts/:id(.:format) {:action=>"destroy", :controller=>"posts"}
categories GET /categories(.:format) {:action=>"index", :controller=>"categories"}
POST /categories(.:format) {:action=>"create", :controller=>"categories"}
new_category GET /categories/new(.:format) {:action=>"new", :controller=>"categories"}
edit_category GET /categories/:id/edit(.:format) {:action=>"edit", :controller=>"categories"}
category GET /categories/:id(.:format) {:action=>"show", :controller=>"categories"}
PUT /categories/:id(.:format) {:action=>"update", :controller=>"categories"}
DELETE /categories/:id(.:format) {:action=>"destroy", :controller=>"categories"}
post_comments GET /posts/:post_id/comments(.:format) {:action=>"index", :controller=>"comments"}
POST /posts/:post_id/comments(.:format) {:action=>"create", :controller=>"comments"}
new_post_comment GET /posts/:post_id/comments/new(.:format) {:action=>"new", :controller=>"comments"}
edit_post_comment GET /posts/:post_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"}
post_comment GET /posts/:post_id/comments/:id(.:format) {:action=>"show", :controller=>"comments"}
PUT /posts/:post_id/comments/:id(.:format) {:action=>"update", :controller=>"comments"}
DELETE /posts/:post_id/comments/:id(.:format) {:action=>"destroy", :controller=>"comments"}
posts GET /posts(.:format) {:action=>"index", :controller=>"posts"}
POST /posts(.:format) {:action=>"create", :controller=>"posts"}
new_post GET /posts/new(.:format) {:action=>"new", :controller=>"posts"}
edit_post GET /posts/:id/edit(.:format) {:action=>"edit", :controller=>"posts"}
post GET /posts/:id(.:format) {:action=>"show", :controller=>"posts"}
PUT /posts/:id(.:format) {:action=>"update", :controller=>"posts"}
DELETE /posts/:id(.:format) {:action=>"destroy", :controller=>"posts"}
Index works fine, I am able to list posts.
If I do in in console:
Post.find(3, :params=>{:category_id=>2})
I am able to get the desired response but from the browser I get the following error.
Failed. Response code = 404. Response message = Not Found.

try updating your routes to be
resources :categories do
resources :posts do
resources :comments
end
end
then you should be able to access them as nested resources. Not sure where the < Connector is going, is Connector a model based on ActiveModel?

Also, if you are nesting more than one level, you should really take a second look at your application design, as this quickly becomes a headache, see: http://weblog.jamisbuck.org/2007/2/5/nesting-resources (this code is rails 2.x style, but the design issues remain)
