Here is how I did it, with internationalization and ordering, and auto select the current_user role if already defined. It assumes that you have a locale file with a roles: category containing all your enum roles such as :

# your locale file
en:
 roles:
  admin: "Administrator"
  mode: "Moderator"


# model user.rb
enum role: { admin: 0, mode: 1 }
ROLES = User.roles.map { |r,| [I18n.t("roles.#{r}"), r] }.sort_by { |r| I18n.t("roles.#{r}") }

# view

<%= f.select :role, User::ROLES, { prompt: t("users.roles.prompt"), selected: @user.role }, { class: "form-control" } %>
