不需要（元？）中的Ruby/Rails數據

Question

我有兩個模型（問題和解答）稍微跟隨流行Railscasts：

class Question < ActiveRecord::Base 
    has_many :answers 
    accepts_nested_attributes_for :answers, :allow_destroy => true 
end 

class Answer < ActiveRecord::Base 
    belongs_to :question 
    attr_accessible :content 
end 

的答案是建立（我的應用程序的目的）內編輯方法我question_controller.rb的：

2.times do 
    @question.answers.build 
end 

和編輯視圖中呈現 - edit.html.haml爲：

= f.fields_for :answers do |builder| 
    = render "answer_fields", :f => builder 

當我想顯示答案時出現問題。裏面show.html.haml，我做的：

= for answer in @question.answers 
    = answer.content 

答案內容顯示，但我也得到這個（不想要的）HTML代碼：

[#<Answer id: 11, question_id: 22, content: "100", created_at: "2012-04-02 08:34:50", updated_at: "2012-04-02 08:34:50">,] 

如何刪除這個有什麼想法？我找不到這些額外數據的存在。

非常感謝提前！

Answer 1

更換

= for answer in @question.answers 
    = answer.content 

隨着

- for answer in @question.answers 
    = answer.content 

（第一版打印出@ question.answers的內容，第二隻運行循環）
