太好了！IT 工作正常！

```plaintext
  self.add_model_callback(UserEmail, :after_commit, on: :update) do
    puts "#{'-'*50}\nEMAIL YES ADDRESS IS UPDATED for #{self.user_id}!!!!\n#{'-'*50}\n"
    user = User.find(self.user_id)
    GroupDomain.add_to_group_if_in_whitelisted_domain(user)
  end

```

非常感谢，@Falco！
