Rails 测试一个预定的邮件 rake 任务答案

【问题描述】：

我有一个 rake 任务，应该每天向用户发送一封邮件，他们的日常字段 == true。（我的项目中已经有一个正在运行的邮件实现，它在创建帐户和密码重置时发送邮件）。我正在使用Whenever gem

问题是，由于我不在生产中，我不知道如何测试它是否有效。

这是我的 UserMailer：

def daily_mail(user)
    @user = user
    mail to: user.email, subject: "Mail journalier"
end

我的耙子任务：

desc "向用户发送电子邮件"

task :email_sender => :environment do |_, args|
  User.find_each do |user|
    UserMailer.daily_mail(user).deliver if user.daily == true
  end
end

还有我的 schedule.rb ：

every :day, :at => '12pm' do # Use any day of the week or :weekend, :weekday
  rake "email_sender"
end

我是在看教程后这样做的：

whenever --update-crontab store (and tried with --set too)

我尝试执行 crontab -l 并得到了这个：

# Begin Whenever generated tasks for: store

0 12 * * * /bin/bash -l -c 'cd /Users/Marco/Documents/TBProject && RAILS_ENV=production bundle exec rake email_sender --silent'

# End Whenever generated tasks for: store

# Begin Whenever generated tasks for: /Users/Marco/Documents/TBProject/config/schedule.rb

0 12 * * * /bin/bash -l -c 'cd /Users/Marco/Documents/TBProject && RAILS_ENV=production bundle exec rake email_sender --silent'

# End Whenever generated tasks for: /Users/Marco/Documents/TBProject/config/schedule.rb

他们是一种测试（或了解）我的任务是否适用于生产环境的方法吗？

更新：

我尝试运行“rake email_sender”，我在 development.log 中得到了这个：

所以它向仅有的两个用户发送了每天 == true 的邮件，所以我的方法有效。但是预定的工作有效吗？

【解决方案1】：

将 UserMailer 更改为

def daily_mail(user)
    @user = user
    mail_to :user.email, subject: "Mail journalier"
end

【讨论】：

我正在使用邮件：用于帐户激活，它可以工作
