Using wildcard routes and url_helpers in rails 4

Question

I have a wildcard route set up - but I cannot get the built in helpers to generate the correct url.

routes.rb

resources :projects do
    patch 'do/*action', to: 'projects#do', as: 'do'
end

rake routes

project_do PATCH  /projects/:project_id/do/*action(.:format)         projects#do

which looks ok, but my helper project_do_path(project) generates /projects/1234/do/do

1) why how do I get rid of the second do 2) can I configure it to include the action in the helper?

I have read http://guides.rubyonrails.org/routing.html#route-globbing-and-wildcard-segments but it does not talk about helpers in the wildcard section.

thanks and best regards

Answer 1

Having the following routes

resources :blog, only: [:index, :show] do
  patch 'do/*do_action', to: 'rsvps#index', as: :do
end

gives me the following url

   blog_do PATCH  /blog/:blog_id/do/*do_action(.:format)    rsvps#index
blog_index GET    /blog(.:format)                           blog#index
      blog GET    /blog/:id(.:format)                       blog#show

blog_do_path now requires 2 arguments

blog_do_path(project, 'asd')

then in your controller action, params[:do_action] will be 'asd'
