For some reason the conventional path names for a particular controller are not working? (Rails 3.1)

I created a controller using ryan bates nifty scaffold. Just a controller, no underlying model.

in the controller I have

```
class ProjectTemplatesController < ApplicationController
# a bunch of stuff

  def new
    @project = Project.new
  end

#more stuff
end

```

in my view (app/views/project\_templates/index.html.erb) I have:

```
<p><%= link_to "New Project Templates", new_project_templates_path %></p>

```

however I get the error

```
undefined local variable or method `new_project_templates_path' for #<#<Class:0x2ab9c24>:0x2ab80e0>

```

in my routes.rb file I declared the controller as a resource like all the others

```
resources :project_templates 

```

**If I change the link to use** 

`<%= link_to "New Project Templates", {:controller=>"project_templates, :action=>"new"} %>`

**then it works perfectly?!** Why doesnt the naming convension of action\_controller\_path work in this case?
