我一直在关注相当旧的教程,以便创建一个联系表单,然后创建一个发送给站点管理员的邮件程序。我想遇到一些问题,因为我在rails 4.1.1上并且教程太旧了!我想知道是否有人能给我一些指导 - 我正在学习铁轨。我目前得到的错误是MessagesController中的NoMethodError#为#创建未定义的方法`subject'   subject message.subject

这是我的代码

消息控制器:

class MessagesController < ApplicationController
  before_action :set_message, only: [:show, :edit, :update, :destroy]

  # GET /messages
  # GET /messages.json
  def index
    @messages = Message.all
  end

  # GET /messages/1
  # GET /messages/1.json
  def show
  end

  # GET /messages/new
  def new
    @message = Message.new
  end

  # GET /messages/1/edit
  def edit
  end

  # POST /messages
  # POST /messages.json
  def create
    @message = Message.new(message_params)

respond_to do |format|
  if @message.save
    ContactMailer.deliver_message(@message)
    flash.now[:notice] = 'Thank you for your message!'
    format.html { redirect_to root_path }
    format.json { render :show, status: :created, location: @message }
  else
    format.html { render :new }
    format.json { render json: @message.errors, status: :unprocessable_entity }
  end
end

#PATCH / PUT / messages / 1   #PATCH / PUT /messages/1.json   def更新     respond_to do | format |       if @ message.update(message_params)         format.html {redirect_to @message,注意:'消息已成功更新。' }         format.json {render:show,status :: ok,location:@message}       其他         format.html {render:edit}         format.json {render json:@ message.errors,status :: unprocessable_entity}       结束     结束   端

#DELETE / messages / 1   #DELETE /messages/1.json   def destroy     @ message.destroy     respond_to do | format |       format.html {redirect_to messages_url,注意:'消息已成功销毁。' }       format.json {head:no_content}     结束   端

私人     #使用回调来共享操作之间的常见设置或约束。     def set_message       @message = Message.find(params [:id])     端

# Never trust parameters from the scary internet, only allow the white list through.
def message_params
  params.require(:message).permit(:name, :email, :company, :phone, :subject, :body)
end

class ContactMailer < ActionMailer::Base

Email from your web site

From: <%= @message.name %>

Company: <%= @message.company %>

Phone: <%= @message.phone %>

Message: <%= @message.body %>

def deliver_message(message)
  subject    message.subject
  body       :message => message
  recipients CONTACT_RECIPIENT
  from       message.email
  sent_on    Time.now
end

应该是

def deliver_message(message)
  @message = message
  mail(subject: message.subject, body: message.body, recipients: CONTACT_RECIPIENT, from: message.email, sent_on: Time.now)
 end
