My Register is functionnal but i want to add the username to my table,

[info] Sent 200 in 371ms

How can I had my username to the query ?
Thank.

It is probably a bad casting in the changeset, please show your User schema.

My schema looks like this :

defmodule Gotham.Users.User do
  use Ecto.Schema
  use Pow.Ecto.Schema

  schema "users" do

    pow_user_fields()

    timestamps()
  end


end

Maybe i have to change or add something ?
