Transactions

There appears to be several ways to handle transactions, but I'd like to really narrow in on a clean way to handle logging entries from within a transaction. Let's use a simple example such as a Post. So when I create a Post from a Phoenix LiveView, I'd like to call a wrapper action for it such as Post.create_with_log(%{title: title}) Then in my Post resource file, I could possibly: 1) Create a code_interface definition such as define(:create, args: [:title], action: :create_with_log) 2) Define the action such as:

  actions do
    create :create_with_log do
      argument(:title, :string)      
      Post.create!(title: ^arg(:title))
      Post.log!(:create, "Created a new post.")
    end
  end

  actions do
    create :create_with_log do
      argument(:title, :string)      
      Post.create!(title: ^arg(:title))
      Post.log!(:create, "Created a new post.")
    end
  end

Of course this is simplified not fully working. But it's not clear to me if this is the idiomatic way to handle something like this. I can use Flows or even wrap an Ecto.Multi call, but seems that actions are already transactional and I should be able to re-use the mechanism for this. Thoughts?
