我在Rails應用程序中使用惡毒的PDF生成PDF。這是由我的控制器中的一個私有函數generate_pdf完成的，因爲在購買過程中，我想生成該pdf，然後使用郵件函數將該pdf發送給用戶。在Rails應用程序中通過惡意pdf生成pdf文件時出現多個渲染錯誤
錯誤
Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return".
代碼是騙人的東西這個。
def place_order
... some code
download_new_pdf(@pur)
UserMailer.confirm_order(@pur).deliver
format.html { redirect_to(:action=>'order_confirmed/'[email protected][:id].to_s) }
end
和輔助功能將
def download_new_pdf(id)
@my_ticket = Purchase.find(id)
@event = Event.find(@my_ticket[:event_id])
render :pdf => "#{@my_ticket[:random_no]}.pdf",
:template => 'tickets/download_invoice.html.erb',
:save_to_file => Rails.root.join('public/data/docs', "#{@my_ticket[:random_no]}.pdf")
end
place_order會做所有的東西，DB和結束時生成PDF，發送郵件，並重定向到構象頁。但在這裏它給我多渲染
format.html { redirect_to(:action=>'order_confirmed/'[email protected][:id].to_s) }
和
render :pdf => "#{@my_ticket[:random_no]}.pdf",
:template => 'tickets/download_invoice.html.erb',
:save_to_file => Rails.root.join('public/data/docs', "#{@my_ticket[:random_no]}.pdf")
我試圖把和回報，但仍然沒有運氣錯誤堂妹，任何幫助，將不勝感激。謝謝 ！！！
