ruby-on-rails - ActionMailer 错误的参数数量错误

Question

我有一个 Rails 应用程序，可以让您请求注册邀请。根据要求，我会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”。出于某种原因，行 UserMailer.request(@request).deliver 给我这个错误 ArgumentError in RequestsController#create -- wrong number of arguments (0 for 1)

有什么想法吗？

请求 Controller

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

request.html.haml

You have requested to join in

ma​​ilers/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 并查看它是否有效。
