I have it:
resources :users do collection do get 'blah' end end
I want to do this action (blah) for both posts and now, maybe?
You can simply enter the same name for the mail route as follows:
resources :users do collection do get 'blah' post 'blah' end end
Both routes will have the same controller, action and url_helpers
It looks like the verb restrictions are what you want.
match 'blah', to: 'users#blah', via: [:get, :post]
or
resources :users do collection do match 'blah', via: [:get, :post] end end
