Rails - May 2009 - ActionController::RoutingError -> Functional Tests and :path_prefix in routes.rb

Hi,

I''m trying to write a test for my ProfilesController, which I mapped
in my routes.rb, using:

map.resource :profile, :path_prefix => '':account''

This way, I have routes like:

               profile POST   /:account/profile
{:controller=>"profiles", :action=>"create"}
     formatted_profile POST   /:account/profile.:format
{:controller=>"profiles", :action=>"create"}
           new_profile GET    /:account/profile/new
{:controller=>"profiles", :action=>"new"}
 formatted_new_profile GET    /:account/profile/new.:format
{:controller=>"profiles", :action=>"new"}
          edit_profile GET    /:account/profile/edit
{:controller=>"profiles", :action=>"edit"}
formatted_edit_profile GET    /:account/profile/edit.:format
{:controller=>"profiles", :action=>"edit"}
                       GET    /:account/profile
{:controller=>"profiles", :action=>"show"}
                       GET    /:account/profile.:format
{:controller=>"profiles", :action=>"show"}
                       PUT    /:account/profile
{:controller=>"profiles", :action=>"update"}
                       PUT    /:account/profile.:format
{:controller=>"profiles", :action=>"update"}
                       DELETE /:account/profile
{:controller=>"profiles", :action=>"destroy"}
                       DELETE /:account/profile.:format
{:controller=>"profiles", :action=>"destroy"}

My problem is that, when running the following test:

  def test_new
    get :new
    assert_redirected_to new_session_path
  end

I get the error:

test_new(ProfilesControllerTest):
ActionController::RoutingError: No route matches
{:controller=>"profiles", :action=>"new"}
...

I can''t understand why ''get :new'' can''t find
that route and, on the
other hand, ''rake routes'' does recognize it.

This part of my application works fine (including :url => {:controller
=> ''profiles'', :action => ''create''} in
the form_for tags). Though, I
don''t know how to write the proper tests. Do I have to pass any extra
parameter to ''get''? Do you think is it a bit silly to use this
mapping?

Thanks in advance,

Pablo.
