How to fix routing error when using concerns in Rails up to 3.2.22.1

tl;dr

Don't write resources :people, :concerns => :trashable

Write

resources :people do
  concerns :trashable
end

Why

Writing a controller spec I encountered this error:

Failure/Error: get :index
ActionController::RoutingError:
  No route matches {:controller=>"people"}

caused by this route definition

resources :people, :concerns => :trashable

which renders strange routes:

      trash_person PUT    /people/:id/trash(.:format)             people#check {:concerns=>:trashable}
            people GET    /people(.:format)                       people#index {:concerns=>:trashable}
                   POST   /people(.:format)                       people#create {:concerns=>:trashable}
        new_person GET    /people/new(.:format)                   people#new {:concerns=>:trashable}
       edit_person GET    /people/:id/edit(.:format)              people#edit {:concerns=>:trashable}
            person GET    /people/:id(.:format)                   people#show {:concerns=>:trashable}
                   PUT    /people/:id(.:format)                   people#update {:concerns=>:trashable}
                   DELETE /people/:id(.:format)                   people#destroy {:concerns=>:trashable}

Note the {:concerns=>:trashable} at the end of each route.

The fix

… was to write the routes with another syntax …

resources :people do
  concerns :trashable
end

… and now my routes are fine.
