Handles the invitation schema for user.

Customize PowInvitation associations or fields

If you need to modify any of the associations or fields that PowInvitation adds to the user schema, you can override them by defining them before pow_user_fields/0:

defmodule MyApp.Users.User do
  use Ecto.Schema
  use Pow.Ecto.Schema
  use Pow.Extension.Ecto.Schema,
    extensions: [PowInvitation]

  schema "users" do
    belongs_to :invited_by, __MODULE__
    has_many :invited_users __MODULE__, foreign_key: :invited_by_id, on_delete: delete_all

    field :invitation_token, :string
    field :invitation_accepted_at, :utc_datetime

    pow_user_fields()

    timestamps()
  end
end
