I have the same issue, the book refers to code that is seemingly a previous iteration of what is available on github. There’s no direct means of following along with the book as the code referenced doesn’t exist.

e.g.

Open up lib/meow_web/live/meerkat_live.ex, and you’ll see our basic MeerkatLive-LiveView for displaying the meerkat data.

defmodule MeowWeb.MeerkatLive do use MeowWeb, :live_view
  alias Meow.Meerkats
  def mount(_params, _session, socket), do: {:ok, socket}
  def handle_params(_params, _url, socket) do {:noreply, assign_meerkats(socket)}
  end

  defp assign_meerkats(socket) do
    assign(socket, :meerkats, Meerkats.list_meerkats())
  end 

end

The referenced module is actually 85 lines long and doesn’t include an implementation of assign_meerkats as referenced above https://github.com/PJUllrich/pragprog-book-tables/blob/main/lib/meow_web/live/meerkat_live.ex

This problem persists with no apparent attempt to address it by the author. I find that it renders the book nearly useless. Please address this issue.

Hi Peter,

Thanks for the answer. The problem is that the book assumes an existing project to work on. If this is simply an easily generated project it would be nice to have some instructions on generating it.
