問題

我有一個應用程序,在那裏可以對一個禮物作出承諾。一旦做出承諾,應該向出質人發送確認電子郵件。嘗試發送郵件時,服務器正在發出500 Internal Server Error爲什麼ActionMailer不能提供我的mongoid對象?

語境:

  • Ruby on Rails的3.2.0
  • 的ActionMailer 3.2.0
  • Mongoid 2.4.3
  • 薄1.3.1

我用的ActionMailer在以前的應用程序,但這是我第一次使用Mongoid。

代碼

class Pledge 
    include Mongoid::Document 
    field :name, :type => String 
    field :email, :type => String 
    field :amount, :type => Float 

    embedded_in :gift 
end 


class PledgesController < ApplicationController 
    def create 
    @gift = Gift.find(params[:gift_id]) 
    @pledge = @gift.pledges.new(params[:pledge]) 

    respond_to do |format| 
     if @pledge.save 
     PledgeMailer.pledge_confirmation(@pledge).deliver 
     format.html { redirect_to :root, notice: 'Pledge successfully created.' } 
     else 
     ... 
     end 
    end 
    end 
... 
end 


class PledgeMailer < ActionMailer::Base 
    default :from => "[email protected]" 

    def pledge_confirmation(pledge) 
    @pledge = pledge 
    mail(:to => pledge.email, :subject => "Thanks - pledge confirmation") 
    end 
end

所以我們說Sam Andreas[email protected]承諾$42.42禮品4f2695009f5b7f3464000001

這愉快地保存到Mongodb並重定向到:root。隨着加入呼叫PledgeMailer,我們得到:

努力奮鬥,但不能看到那裏的錯誤是在pledge_confirmation

你有什麼建議嗎? :)

嘗試使用'cat -v pledge_mailer.rb',它應該顯示任何奇怪字節的位置。 – 2012-02-08 03:46:32

@ muistooshort謝謝!我沒有發現其他字節。但我按照Mischa的回答重新創建了它,並解決了問題。 – 2012-02-08 04:15:21

你的代碼看起來不錯。錯誤是抱怨「無效的多字節字符(US-ASCII)」。你最好從零開始重新創建pledge_mailer.rb並用字符集UTF-8而不是US-ASCII保存。

謝謝@mischa。這沒有竅門:) – 2012-02-08 04:14:17
