On page 168 of Programming Phoenix the instruction is to create a video. but when I attempt to run the command listed in the book

iex(1)> video = %Rumbl.Video{id: 1, slug: "hello"}

I get the an error ... 😞

Stack trace:

Just checked and Creating videos isn't working in the UI either:

Re-running mix run priv/repo/seeds.exs to create the categories meant that I can create videos:

But still have the defimpl issue: #52

obviously it wasn't going to work until I added the slug to the videos model... duh!
