Programming Phoenix LiveView: Missing code snippet / assigns reference (pg 73)

Here, we add two more keys to the socket.assigns. To set the :session_id key, we copy the session ID directly. Then, we use Accounts.get_user_by_session_token/1 to set the :current_user key.

But, there is no actually call to this function in the preceding code snippet. That code snippet is also repeated in the generated PDF. B6

The correct code snippet is as follows:

# lib/pento_web/live/wrong_live.ex
def mount(_params, session, socket) do

  {
    :ok,
    assign(
      socket,
      score: 0,
      message: "Guess a number.",
      session_id: session["live_socket_id"],
      current_user: Pento.Accounts.get_user_by_session_token(session["user_token"])
    )
  }
end

Look out for that correction in the next release!
