延迟在Rails中发送电子邮件？

Question

我正在使用delay_job延迟将信息从我的应用程序发送到FreeagentCentral（会计软件包）。 同时，它还使用PostmarkApp的gem发送两封电子邮件。

# POST /kases
# POST /kases.xml
def create
@company = Company.find(params[:kase][:company_id])
@kase = @company.kases.create!(params[:kase])

respond_to do |format|
UserMailer.delay.deliver_makeakase("email@address.com", "Highrise", @kase) if    params[:sendtohighrise]
UserMailer.delay.deliver_makeakaseteam("email2@address.com", "Highrise", @kase) if params[:notify_team_of_creation]
@kase.delay.create_freeagent_project(current_user) if params[:send_to_freeagent]

#flash[:notice] = 'Case was successfully created.'
flash[:notice] = fading_flash_message("Case was successfully created.", 5)

format.html { redirect_to(@kase) }
format.xml  { render :xml => @kase, :status => :created, :location => @kase }
end
end

上面的代码不会引发任何错误-但是不会发送电子邮件。 我想知道我做错了什么吗？

是这样的还是我错过了一些东西：

UserMailer.delay.deliver_makeakaseteam("email2@address.com", "Highrise", @kase) if params[:notify_team_of_creation]

谢谢，

来自（collectiveidea）延迟工作文档

由于在Rails 3中邮件程序的实现方式，我们不得不做一些工作才能使delay_job正常工作。

没有延迟的工作

Notifier.signup(@user).deliver

与延迟工作

Notifier.delay.signup(@user)

删除.deliver方法以使其起作用。 这并不理想，但是这是我们目前可以做的最好的事情。

希望这可以帮助
