quick REST question

Is this possible?

domain.com/users

domain.com/users/1/products

domain.com/products

I'd like to view all the products for a User and also all of the entire products. From what I've tried, this does not work:

map.resources :users do |users|     users.resources :products end

map.resources :products

You have to use a name_prefix for the nested resources. Jamis Buck wrote about it two months ago: Buckblog: Nesting resources

cheers :slight_smile:

Thanks a lot bobes! Specifically comment number 15 was exactly what I was looking for. My routes now look like this:

map.resources :users do |users|     users.resources :products, :controller => "user_products" end

map.resources :products

Now I obviously had to create an extra controller: UserProducts < ApplicationController

Actually my last post didn't work. It would read the User id as the action and the user_products as the id. I changed my routes to this with success:

map.resources :user_products, :path_prefix => "users/:user_id"

Is this the best way to do this?

Looks like my second post didn't go through. Here is what I had

map.resources :users do |users|     users.resources :products, :controller => "user_products" end

map.resources :products

So you’ve got a ProductsController and UserProductsController? If so, then this could be a good way to go. If the views are the same for user products and all products than having one controller and one set of views is a better solution.

The routes would be:

map.resources :users do |users| users.resources :products, :name_prefix => “user_” end map.resources :products

And in actions you would have something like:

def index params[:user_id].nil? ? Products.find(:all) : User.find(params[:user_id]).products end

You could also extract the condition to a before_filter, let me know if you have any problems with this…

I actually needed to use the same views so this works perfectly. I ended up using an if/else loop because I needed to render one different view. Thanks! (now I have to go back and delete all the user_products files .....)
