在模型中使用“puts”是否有更好的替代方案？

Question

我在遗留项目中有一个类，如下所示：

class UserObserver < ActiveRecord::Observer
  def after_create(user)
    unless Rails.env == "development"  # don't spam users when running legacy migrations
      begin
        UserMailer.welcome(user).deliver
        subscribe_user_to_new_account_mailinglist user
      rescue
        # THE FOLLOWING LINE IS THE ONE THAT BOTHERS ME
        puts "User##{user.id} - Signed up using an invalid email address."
      end
    end
  end
end

如你所见，那里有puts。当我运行我们的测试套件时，我得到这样的输出：

be rspec spec/models/user_spec.rb
User#1 - Signed up using an invalid email address.
...User#1 - Signed up using an invalid email address.
..User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.User#1 - Signed up using an invalid email address.
.

我不是那种杂乱无章的粉丝。好像我应该只看到绿点。

在该行而不是puts上做什么更好？

在救援中你可以使用： -

flash[:error] = error.message "User##{user.id} - Signed up using an invalid email address." 

这也将使测试成为绿色。
