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
端
#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

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
