Having tried everything:

  • Phoenix to v. 1.4.1
  • mix deps.clean
  • coping the source code of the book up to Ch. 8

I still get:

rumbl ∆ mix test
** (Postgrex.Error) ERROR 42P07 (duplicate_table): relation "users" already exists

    (ecto) lib/ecto/migration/runner.ex:102: Ecto.Migration.Runner.flush/0
    (stdlib) timer.erl:181: :timer.tc/2

Of course I did ecto.reset too plenty of times.

Anyone that can get me on track again?

That worked.

I had to outcomment the following for some reason.

  socket "/socket", RumblWeb.UserSocket
  # ,
  #   websocket: true,
  #   longpoll: false

Phoenix v1.4.1
