The create action in the UserController must now use our new registration_changeset, like this:

authentication/listings/rumbl/web/controllers/user_controller.change1.ex

def create(conn, %{"user" => user_params}) do
  changeset = User.registration_changeset(%User{}, user_params)
  case Repo.insert(changeset) do
    {:ok, user} ->
      conn
      |> put_flash(:info, "#{user.name} created!")
      |> redirect(to: user_path(conn, :index))
    {:error, changeset} ->
      render(conn, "new.html", changeset: changeset)
  end
end
