在模型中使用「puts」有沒有更好的選擇？

Question

我有一箇舊的項目，看起來像這樣一類：

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 

正如你可以看到，有這麼puts那裏。當我運行我們的測試套件，我得到的輸出是這樣的：

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. 
.

我沒有多餘的雜亂的大風扇。似乎我應該只看到綠點。

在該行上而不是puts上做什麼更好？

在拯救你可以使用： -

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

這也將使得測試綠色。
