我正在用RubyonRails创建一个具有mailer功能的博客。我想在新用户注册后向他们发送一封欢迎电子邮件。不幸的是，在我当前的代码设置中，我收到了一个错误（“分配属性时，必须将哈希作为参数传递。”）！我已经用尽了我所有的脑力来纠正这个问题，我将非常感谢任何人能给我的任何帮助

这是我的代码：订阅者控制器

class SubscribersController < ApplicationController
before_action :set_subscriber, only: [:show, :edit, :update, :destroy]

 respond_to :html

  def send_welcome
  NotificationMailer.welcome(params[:id]).deliver
    redirect_to new_subscriber_path
  end  

  def index
    @subscribers = Subscriber.all
    respond_with(@subscribers)
  end

  def show
    @subscriber = Subscriber.find(params[:id])
    respond_with(@subscriber)
  end

  def new
    @subscriber = Subscriber.new
    respond_with(@subscriber)
  end

  def edit
   @subscriber = Subscriber.find(params[:id])
  end

  def create
    @subscriber = Subscriber.new(subscriber_params)
    if @subscriber.save
        NotificationMailer.welcome(@subscriber)
        redirect_to posts_path, notice: "You have successfully subscribed."

    else 
      render 'new'
    end 

  end

  def update
    @subscriber = Subscriber.find(params[:id])
    @subscriber.update(subscriber_params)
    respond_with(@subscriber)
  end

  def destroy
    @subscriber = Subscriber.find(params[:id])
    @subscriber.destroy
    respond_with(@subscriber)
  end

  private
    def set_subscriber
      @subscriber = Subscriber.find(params[:id])
    end

    def set_email
      @email = Subscriber.find(params[:email])
    end  

    def subscriber_params
      params.require(:subscriber).permit(:name, :email, :mobile)
    end
end

Notification_mailer - Welcome Method

    class NotificationMailer < ActionMailer::Base
  default from: "myemail@gmail.com"

  # Subject can be set in your I18n file at config/locales/en.yml
  # with the following lookup:
  #
  #   en.notification_mailer.welcome.subject
  #
  def welcome(subscriber)
    @subscriber = Subscriber.new(subscriber)
    @url = 'http://localhost:3000/posts'
    mail :to => "#{@subscriber.name} <#{@subscriber.email}>",
          :from => "myemail@gmail.com",
          :subject => 'Welcome to My Blog'
    end

我目前正在使用rails 4，并且安装了Desive，因此我可以作为站点管理员登录

提前感谢您发布的任何帮助

更新

为了让一切正常工作，我对通知邮件器进行了更改，并在订阅者控制器中重新配置了create方法。代码如下：

通知邮递员

   def welcome(subscriber)
   @subscriber = subscriber
   @url = 'http://localhost:3000/posts'
   mail to:  "#{@subscriber.name} <#{@subscriber.email}>",
      from:  "wildgenius99@gmail.com",
      subject: 'Welcome to My Blog'
   end

请您也发布错误消息好吗？谢谢您正在将实际的订户对象传递给邮件程序，然后调用

subscriber.new（@subscriber）

，这将从您现有的订户对象创建一个新订户。尝试将

@subscriber=subscriber.new（subscriber）

的行替换为

@subscriber=subscriber

@Sixty4Bit以下是错误消息：ArgumentError in subscribers controller#分配属性时创建，您必须传递一个散列作为参数。@MikeManfrin我尝试了您的建议，更改后应用程序仍然不会发送电子邮件。您的

新

表单是什么样子的，它将

订户参数

馈送到

\create

。错误消息可能表示问题在这里：

@subscriber=subscriber.new（subscriber_参数）
