ruby-on-rails - 在模型中使用“放置”是否有更好的选择？

Question

我在一个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

如您所见，那里puts有。当我运行我们的测试套件时，我得到如下输出：

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.
.

我不喜欢额外的混乱。好像我应该只看到绿点。

在那条线上而不是puts?

在救援中，您可以使用：-

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

这也将使测试变为绿色。
