I have this code snippet from the getting started guide for ash_phoenix:
Repo GitHub - albinkc/my_ash_phoenix_app_tut · GitHub

def handle_event("update_post", %{"form" => form_params}, socket) do
    case AshPhoenix.Form.submit(socket.assigns.update_form, params: form_params) do
      {:ok, _post} ->
        posts = Blog.list_posts!()

        {:noreply, assign(socket, posts: posts, post_selector: post_selector(posts))}

      {:error, update_form} ->
        {:noreply, assign(socket, update_form: update_form)}
    end
  end

notice the uuids are different in the form_params vs the postgres statement. Furthermore, if I delete all but one record from the db table and then try the update, I get this cryptic warning. No db update occurs in this case.
