RSpec, nested routes and :path_prefix

Dear list,

In the app we are making we have a rout something like this: map.resources :projects do |projects|   projects.resources :pages, :controller => "Wiki::Pages", :path_prefix => "/projects/:project_id/ wiki", :name_prefix => "project_wiki_" end

But I can't get RSpec(I'm very new to it) to accept this. It keeps throwing errors: ActionController::RoutingError in 'Wiki::PagesController GET 'create' should be successful' No route matches {:action=>"create", :controller=>"wiki/ pages", :project_id=>1}

I get why it throws these errors but not how to fix it. The relavant RSpec:   it "GET 'create' should be successful" do     get 'create', :project_id => 1     response.should be_success   end

How do I modify the get request properly? Thanks in advance!
