如何将像after_commit回调这样的东西附加到Ecto事务？

defmodule MyApp.Repo do
  use Ecto.Repo, otp_app: :my_app
end

defmodule MyApp.User do
  use Ecto.Schema
  import Ecto.Changeset

  schema "users" do
    field :name, :string
    field :email, :string
  end

  def changeset(user, attrs) do
    user
    |> cast(attrs, [:name, :email])
    |> validate_required([:name, :email])
  end
end

defmodule MyApp.TransactionExample do
  alias MyApp.Repo
  alias MyApp.User

  def create_user_with_callback(attrs) do
    Repo.transaction(fn ->
      %User{}
      |> User.changeset(attrs)
      |> Repo.insert()

      # Attach after_commit callback
      {:ok, user} ->
        Repo.transaction(fn ->
          # Perform some operation after commit
          IO.puts("User #{user.id} created successfully")
          :ok
        end, after_commit: fn _ ->
          IO.puts("After commit callback executed")
        end)
    end)
  end
end

Repo.transaction(fn ->
  %User{}
  |> User.changeset(attrs)
  |> Repo.insert()

  {:ok, user} ->
    Repo.transaction(fn ->
      # Perform some operation after commit
      IO.puts("User #{user.id} created successfully")
      :ok
    end, after_commit: fn _ ->
      try do
        IO.puts("After commit callback executed")
      rescue
        e in _ ->
          IO.puts("Error in after_commit callback: #{inspect(e)}")
      end
    end)
end)
