Rails delayed_jobs在发送邮件时询问“发件人/发件人”

Question

我试图设置异步电子邮件发送。我正在使用delayed_job。 Withoud delayed_job一切正常，没有任何错误。但是，当我补充一下：

handle_asynchronously :mail_sending_method 

我收到以下错误：

A sender (Return-Path, Sender or From) required to send a message 

我用的ActionMailer用于发送邮件，特别是这样的：

mail(:to => user.email, :from => "notifications@example.com", :subject => "Blah") 

这里是方法：

def phrase_email(user, tweet, keyword, phrase) 
    @user = user 
    @tweet = tweet 
    @keyword = keyword 
    @phrase = phrase 
    mail(:to => user.email, :from => "notifications@example.com", :subject => "Weekapp  Phrase Notification") 
end 

Answer 1

延迟工作w与Rails 3 Mailers不同。

class YourMailer < ActionMailer::Base 
    def phrase_email(user, tweet, keyword, phrase) 
    @user = user 
    @tweet = tweet 
    @keyword = keyword 
    @phrase = phrase 
    mail(:to => user.email, :from => "notifications@example.com", :subject => "Weekapp Phrase Notification") 
    end 
end 

因此，如下使用delay或deliver一边打电话到你的邮件的方法。

YourMailer.delay.phrase_email(user, tweet, keyword, phrase) #With delay 

YourMailer.phrase_email(user, tweet, keyword, phrase).deliver #Without delay 

并从您的YourMailer中删除handle_asynchronously。

在文档here中明确提到。您不能将邮件使用handle_asynchronously。
