Actionmailer实例变量问题Ruby on Rails [英] Actionmailer instance variable problem Ruby on Rails

问题描述

我有一个电子邮件调度程序设置，可以向所有用户发送有关该站点更新的每日电子邮件，

I have an email scheduler setup to send a daily e-mail with updates about the site to all users,

但是，当我尝试发送电子邮件时，邮件，所有变量都返回nil，我假设是因为未明确定义任何内容。即，没有人提交带有电子邮件的表单，单击提交并触发电子邮件，这只是每天发送给所有用户的电子邮件，为简单起见，我们要说其中应包含接收用户的电子邮件地址。

However, when I try and send the e-mail, all variables come back as nil, i'm assuming because nothing is explicitly defined. i.e. No one is submitting a form with their email, clicking submit and triggering an e-mail, it's just a daily email to all users, that for simplicities sake, we'll say should contain the receiving user's email address.

     <%= @user.email %>

在此先感谢您的帮助！

    def newideas_email(user)
    @user = user
    mail(:to => user, :subject => "Here are the latest ideas from your team")
    end

，这是调度程序任务：

    scheduler.every("30m") do  
    Account.all.each do |account|
    account.users.each do |user|
    Newideas.newideas_email(user.email).deliver
    end
    end
    end

，这是实际的电子邮件代码：

and here's the actual e-mail code:

    <% @user.account.ideas.each do |idea| %>  
    <li><%= idea.title %></li> 
    <% end %>

再次感谢！

推荐答案

在您预定的代码中，您正在通过用户的电子邮件地址传递到邮件发件人 Newideas.newideas_email（user.email）。您可能想做的是传递用户对象本身 Newideas.newideas_email（user），因为您的视图模板期望它是 ActiveRecord 。

In your scheduled code, you're passing through the user's email address to the mailer Newideas.newideas_email(user.email). What you probably meant to do was pass the user object itself Newideas.newideas_email(user), because your view template is expecting it to be an ActiveRecord.
