Rails3 Routes - Passing parameter to a member route

I would like to pass an extra parameter to a member route of a resource

something like:

resources :events do
  member do
    get 'register/:participant_type_id'
  end
end

I could only accomplish it开发者_StackOverflow社区 using a static match statement

Looking around the internet I saw that this might be possible in Rails 3.0.2. I'm using 3.0.1 and it certanlly is not.

Am I doing something wrong? or is it really not possible?

thanks

Try this:

resources :events do
  member do
    get 'register/:participant_type_id', :action => 'register'
  end
end

Just to complete the answer with my little findings. It also confused me for quite a while.

In Rails3, the member route with parameters will not have the automatic generated xx_yy_path helper. You need to add it providing the :as => part, omitted the resources name.

Regarding the example provided, to get register_event_path and register_event_url, you need to define it like the following:

resources :events do
  member do
    get 'register/:participant_type_id', :action => 'register', :as => 'register'
  end
end
