我有一个工作方法，当用户通过设置密码激活帐户时向用户发送电子邮件，但由于某种原因它不与我的票据模型方法发送给角色整数为2的用户。票据被创建，但是，我似乎无法使用after_create：method_name来发送电子邮件。当用户提交新票时发送电子邮件给管理员不发送

控制台中有一个错误，似乎是一个生成的错误代码，可能是ActionMailer的问题，但它很难用我得到的所有回报来诊断。

任何帮助，非常感谢！提前致谢！

后好一些试验和错误事实证明我太多的事情，我猜。关于为什么上述工作适用于新用户注册但不适用于我的新机票提交的一些澄清将是更好的答案。

下面是我使用ActionMailer工作的方式。新文件admin_mailer.rb并在ticket.rb中删除after_create和send_ticket_notifier

# /mailers/admin_mailer.rb 
###################################### 
def new_ticket(ticket) 
    @ticket = ticket 
    mail(to: '[email protected]', subject: "New Ticket Submitted") 
end 


# /controllers/tickets_controller.rb 
###################################### 
def create 
    @ticket = Ticket.new(ticket_params) 
    if @ticket.save 
    AdminMailer.new_ticket(@ticket).deliver 
    redirect_to tickets_path, :notice => "Ticket Submitted." 
    else 
    redirect_to tickets_path, :alert => "Unable to submit ticket." 
    end 
    puts @ticket.errors.inspect 
end 


# /views/admin_mailer/new_ticket.html.erb 
###################################### 
<!DOCTYPE html> 
<html> 
    <head> 
    <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' /> 
    </head> 
    <body> 
    <h1>New Ticket <%= @ticket.id %></h1> 
    <strong><%= @ticket.user.name %></strong> 
    <p>Ticket Title: <%= @ticket.title %></p> 
    <p>Ticket Description: <%= @ticket.description %></p> 
    </body> 
</html>
