Used for extensions to extend user schemas.

The macro will add fallback methods to the module, that can be overridden.

Usage

defmodule MyPowExtension.Ecto.Schema do
  use Pow.Extension.Ecto.Schema.Base

  @impl true
  def attrs(_config) do
    [{:custom_field, :string}]
  end

  @impl true
  def changeset(changeset, _config) do
    Ecto.Changeset.validate_required(changeset, [:custom_field])
  end
end
