Programming Phoenix LiveView: Session Data B6.0 (p. 56)
The text talks about adding two keys to assigns, a session_id key and a current_user key, but the example code is only showing the session_id key. The code on the following page adding @current_user.email to the markup will not work.

Hi! Thanks for catching this. The correct code snippet to add is:
# 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
We’ll fix that in the next release
