method

member

rails latest stable - Class: ActionDispatch::Routing::Mapper::Mapping::Scoping::Resources

member(&block)

public

To add a member route, add a member block into the resource block:

resources :photos do
  member do
    get 'preview'
  end
end

This will recognize /photos/1/preview with GET, and route to the preview action of PhotosController. It will also create the preview_photo_url and preview_photo_path helpers.

          with_scope_level(:member) do
            if shallow?
              shallow_scope {
                path_scope(parent_resource.member_scope, &block)
              }
            else
              path_scope(parent_resource.member_scope, &block)
            end
          end
        end
