Change user role for certain emails

[jagoanmamah]

I want to change the user's role for certain emails from Oauth, is that possible?

[danschultzer]

Is this when the user is created or is it for already existing users?

If it's for when the user is created, you can solve it with just the changeset:

defmodule MyApp.Users.User do
  use Ecto.Schema
  use Pow.Ecto.Schema
  use PowAssent.Ecto.Schema

  # ...

  def user_identity_changeset(user_or_changeset, user_identity, attrs, user_id_attrs) do
    user_or_changeset
    |> pow_assent_user_identity_changeset(user_identity, attrs, user_id_attrs)
    |> set_role(attrs)
  end

  defp set_role(changeset, attrs) do
    changeset
    |> Ecto.Changeset.get_field(:email)
    |> email_is_admin?()
    |> case do
      true -> Ecto.Changeset.change(changeset, %{role: "admin"})
      false -> changeset
    end
  end

  defp email_is_admin?("admin@example.com"), do: true
  defp email_is_admin?("admin2@example.com"), do: true
  defp email_is_admin?(_any), do: false
end
