Newbie: Wierd ID not routing by default problem.

Ok so I was having this problem before and thought Id start again from scratch.

Here is an example of my index.html.erb file

<% for user in @users %>   <tr>     <td><%= h user.SurName %></td>     <td><%= h user.ForeName %></td>

    <td><%= link_to 'Show', user %></td>     <td><%= link_to 'Edit', edit_user_path(user) %></td>     <td><%= link_to 'Destroy', user, :confirm => 'Are you sure?', :method => :delete %></td>   </tr> <% end %>

<%= link_to 'New user', new_user_path %>

The links rendered for show edit and destroy are all wrong they basically leave out the ID of the user and so don't work as links

EG: "Show" links to /users/ rather than say /users/10 for example, and "Edit" links to /users//edit rather than /users/10/edit

I find if I edit my code to be more of the form

    <td><%= link_to 'Show', :action => 'show', :id => user.ID %></td>     <td><%= link_to 'Edit', edit_user_path(user.ID) %></td>

Then the paths are fine, but every tutorial I've read seems to imply that this shouldn't be necessary. Am I doing something obvious wrong?

My routes.rb file is very standard

ActionController::Routing::Routes.draw do |map|   map.resources :users

  map.root :controller => "users"

  map.connect ':controller/:action/:id'   map.connect ':controller/:action/:id.:format' end

this should work:

<td><%= link_to 'Show', user_path(user.id) %></td> <td><%= link_to 'Edit', edit_user_path(user.id) %></td> <td><%= link_to 'Destroy', user_path(user.id), :confirm => 'Are you sure?', :method => :delete %>

Ok cool, but does this mean that I've just been reading bad tutorials? Or is it a configuration issue?
