Rails HTML轉義

Question

在Rails 3.2.1幫助程序中有以下代碼，即使我不需要它，我仍然會轉義HTML，並且我無法弄清楚如何關閉此方法中的html轉義（調用生或html_safe不工作）：

module OffersHelper 
    def price_tag(amount) 
    amount = amount.to_f 
    floor = amount.floor 
    cents = ((amount - amount.floor) * 100).to_i 
    content_tag(:h2) do 
     html = floor.to_s 
     html << content_tag(:sup, cents) if cents > 0 
     html 
    end 
    end 
end 

如果我刪除嵌套content_tag（SUP的標籤），將HTML轉義關閉...

嘗試：

module OffersHelper 
    def price_tag(amount) 
    amount = amount.to_f 
    floor = amount.floor 
    cents = ((amount - amount.floor) * 100).to_i 
    out = content_tag(:h2) do 
     html = floor.to_s 
     html << content_tag(:sup, cents) if cents > 0 
     html 
    end 
    out.html_safe 
    end 
end
