ERROR Action Controller RoutingError: No route matches

[CosmicRider]

I am getting this error whenever my erb is displayed.

ERROR ActionController::RoutingError: No route matches [GET] "controller_name/.plugin/jquery.parser.js

*I have stripped my erb to just one "Hello World" statement...other information
Rails 3.2
Ruby 1.9.3
easyui 1.3.2

My routes.rb has
resources :foo, only: index do
  get '/:name", action: :show,    on: :collection
end

my index method contains
render file: 'foo_dir/foo', layout: Foo.config.foo_layout

application.js points only points to jquery 1.8.3.min.js and the easyui.min.js


it is a weird error that I cannot resolve. thanks in advance for any help
