Add IEx.pry to the `create` function in `user_controller.ex`

user_controller.ex

  def create(conn, %{"user" => user_params}) do
    # + + + + + + + + + + + +
    require IEx; IEx.pry  # <-
    # + + + + + + + + + + + +
    case Accounts.create_user(user_params) do
      {:ok, user} ->
        conn
        |> put_flash(:info, "User created successfully.")
        |> redirect(to: user_path(conn, :show, user))
      {:error, %Ecto.Changeset{} = changeset} ->
        render(conn, "new.html", changeset: changeset)
    end
