def meth_name
  # TODO: figure out how to improve this and make easier to follow.
  #
  # Example 1:
  #
  #     resources :users, only: [] do
  #       resources :posts, only: :index
  #     end
  #
  # Results in:
  #
  #     full_as: user_posts
  #     method_name_leaf: nil
  #
  # Example 2:
  #
  #     resources :users, only: [] do
  #       get "posts", to: "posts#index"
  #     end
  #
  # Results in:
  #
  #     full_as: users
  #     method_name_leaf: posts
  #
  # This is because using resources contains all the info we need in parent scopes.
  # The scope.full_as already has the desired meth_name.
  #
  # However, when using the simple create_route methods like get, the parent scope does not contain
  # all the info we need. In this tricky case, the method_name_leaf is set.
  # We then have to reconstruct the meth_name.
  #

  if method_name_leaf
    path_items = @path.to_s.split('/')
    if path_items.size == 1
      join(singularize(full_as), method_name_leaf) # reconstruct
    else
      nil # fallback: do not define url method
    end
  else  # comes from resources
    join(full_as) # construct entirely from scope info
  end
end
