ok here's some code:

prompt>rails my_app
prompt>cd my_app
prompt>script/generate scaffold service_type title:string time_allotment:integer
prompt>rake db:migrate

then edit these files to look like this:

#routes.rb:
ActionController::Routing::Routes.draw do |map|
  map.resources :services, :controller => :service_types
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
end

which produces these routes:

prompt>rake routes
    services GET    /services(.:format)                {:controller=>"service_types", :action=>"index"}
             POST   /services(.:format)                {:controller=>"service_types", :action=>"create"}
 new_service GET    /services/new(.:format)            {:controller=>"service_types", :action=>"new"}
edit_service GET    /services/:id/edit(.:format)       {:controller=>"service_types", :action=>"edit"}
     service GET    /services/:id(.:format)            {:controller=>"service_types", :action=>"show"}
             PUT    /services/:id(.:format)            {:controller=>"service_types", :action=>"update"}
             DELETE /services/:id(.:format)            {:controller=>"service_types", :action=>"destroy"}
                    /:controller/:action/:id           
                    /:controller/:action/:id(.:format)

 #my_app/app/views/service_types/index.html.erb
 <h1>Listing service_types</h1>

<table>
  <tr>
    <th>Title</th>
    <th>Time allotment</th>
  </tr>

<% @service_types.each do |service_type| %>
  <tr>
    <td><%=h service_type.title %></td>
    <td><%=h service_type.time_allotment %></td>
    <td><%= link_to 'Show', service_type %></td>
    <td><%= link_to 'Edit', edit_service_path(service_type) %></td>
    <td><%= link_to 'Destroy', service_type, :confirm => 'Are you sure?', :method => :delete %></td>
  </tr>
<% end %>
</table>

<br />

<%= link_to 'New service_type', new_service_path %>

#my_app/app/views/service_types/new.html.erb
<h1>New service_type</h1>

<% form_for(@service_type) do |f| %>
  <%= f.error_messages %>

  <p>
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </p>
  <p>
    <%= f.label :time_allotment %><br />
    <%= f.text_field :time_allotment %>
  </p>
  <p>
    <%= f.submit 'Create' %>
  </p>
<% end %>

<%= link_to 'Back', services_path %>

when you try to access http://localhost:3000/services/new you get the following error:

undefined method `service_types_path' for #<ActionView::Base:0xb7199a80>

Extracted source (around line #3):

1: <h1>New service_type</h1>

Anyone have any idea why it believes that service_types_path is in my code when it's not?

+1  A: 
<% form_for(@service_type) do |f| %>

remove with

<% form_for(@service_type, :url => services_path, :html => { :method => :post }) do |f| %>
