Question

我有一个rails应用程序，允许您请求邀请注册。根据要求，我保存您的电子邮件并向您发送一封电子邮件，表示感谢“您已请求加入”。由于某种原因，行UserMailer.request(@request).deliver在RequestsController中创建了此错误ArgumentError #create - 错误的参数数量（0表示1）

有什么想法吗？

请求控制器

class RequestsController < ApplicationController
  def new
    @request = Request.new
  end

  def create
    @request = Request.new(params[:request])
    if @request.valid?
      if User.find_by_email(@request.email) || Invitation.find_by_email(@request.email)
        redirect_to log_in_path, notice: "Email already in use"
      elsif @request.save
        @request.save
        redirect_to root_url, :notice => "Request sent."
        UserMailer.request(@request).deliver
      end
    else
        render "new"
    end
  end
end

You have requested to join in

寄件人/ user_mailer.rb

class UserMailer < ActionMailer::Base
  def request(request)
    @request = request
    mail(:to => request.email, :subject => "Requested an invite", :from => 'alain@lootfly.com')
  end
end

Answer 1

我认为request是一个保留字。尝试更改为request_mail并查看其是否有效。

Answer 2

我还猜测你不能在模型Request中命名或者在你的控制器中有一个名为@request的实例变量

ActionMailer错误的参数个数错误
