如何在rake任务中包含ActionMailer类？ [英] How to include ActionMailer class in rake task?

问题描述

我想在我的rake任务中使用ActionMailer，以便在特定时间向人们发送电子邮件。

I want to use ActionMailer in my rake task in order to send emails to people at a particular time.

我在app / mailers文件夹中编写了一个邮件程序类，如下所示：

I have written a mailer class in app/mailers folder like this:

class AlertsMailer < ActionMailer::Base
  default from: '[e-mail]'

  def mail_alert(email_addresses, subject, url)
    @url  = '#{url}'
    mail(to: email_addresses, subject: 'Alert') do |format|
      format.html { render '/alerts/list' }
    end
  end
end

然后在我的rake任务中包括以下行：

Then I included the following line in my rake task:

AlertsMailer.mail_alert(email_addresses, subject)

当我尝试运行rake任务时：

When I try to run the rake task:

rake update_db

我得到以下内容错误：

uninitialized constant AlertsMailer

我认为我必须以某种方式在我的rake任务中加载mailer类，但是我不知道该怎么做。

I think I have to somehow load the mailer class in my rake task, but I don't have any idea how to do that.

请帮助。

推荐答案

我有以下内容，它是工作：

I have the following and it is working:

# in lib/tasks/mailme.rake
task :mailme => :environment do
  UserMailer.test_email(1).deliver
end

# in app/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
  def test_email(user_id)
    @user = User.find_by_id user_id

    if (@user)
      to = @user.email

      mail(:to => to, :subject => "test email", :from => "[e-mail]") do |format|
        format.text(:content_type => "text/plain", :charset => "UTF-8", :content_transfer_encoding => "7bit")
      end
    end
  end
end
