I?m having a strange issue with nested routes though, and was wondering if anyone could shed some light on this? If I have: map.resources :users do |users| users.resources :items end When I try to call <%= link_to_remote ''Delete'', :url => item_url(@item), :with => "''_method=delete''", :confirm => ''Are you sure?'' %>>From inside the user urlhttp://localhost:3001/users/1/items Or edit_item_url(@item.id) it doesn?t always render the correct URL, and sometimes I get a nil error trying to render the url. Not sure what I?m missing here, but any help is greatly appreciated. Thanks. I''ve freezed Edge Rails btw. -- Posted via http://www.ruby-forum.com/.
Still getting to grips with this myself, but I *think* you still need to explicitly declare the items routes as well, so: map.resources :items Rick''s routing_navigator helps with showing what routes are available and that''s help me some, although as I said, still getting to grips with it myself...

If you go with positional params, they have to correspond to the order of params in the route. In your example, the route URL would look like /users/:user_id/items/:id Therefore you need to say item_url(@user, @item) or items_url(@user) That should fix it. You might also consider using item_path instead of item_url. It''s the same without the protocol, host and port bits of the URL, which are generally redundant for that usage. -- Josh Susser http://blog.hasmanythrough.com -- Posted via http://www.ruby-forum.com/.

This is all pretty helpful. Thanks guys. Another thing, is there a way
to get the user from the url?
I''m going to complicate this even more now..
Items can belong to users, and categories. So...
I have this in my routes file:
map.resources :categories do |categories|
categories.resources :items
end
map.resources :users do |users|
users.resources :items
end
Now, if I''m at users/1/items I need a way of being able to have that
user id. However if I''m in categories/1/items I need the category ID.
Do
I have to do an explicit find for each in the index action for items
like:
@user = User.find(params[:user_id])
and
@categroy = Category.find(prams[:category_id])
?
There has to be a better way than this.
Thanks again.

Could dry it out for resources which follow the /categories/1/items/2 convention - # in a base class before_filter :find_resources # imagine resource_chain is extracted from the route as [[''categories'', 1], [''items'', 2]] # set @category = Category.find(1), @item = @category.items.find (2), etc. def find_resources name, id = resource_chain.shift root = name.classify.constantize.find(id) instance_variable_set "@#{name.singularize}", root resource_chain.inject(root) do |last, (associate, id)| instance_variable_set "@#{associate.singularize}", last.send (associate).find(id) end end Then your resource controllers can drop the find_* before_filters. jeremy
