在 CalendarMailerPreview Rails 邮件程序预览中找不到电子邮件 'email_calendar'

Question

我已经创建了一个基本的邮件程序，但无法使用以下路径查看预览：http://localhost:3000/rails/mailers/calendar_mailer/calendar_email

这是我的邮件、预览和电子邮件正文代码：

calendar_mailer.rb:

class CalendarMailer < ActionMailer::Base
  default from: "notifications@cogsmart.com"

  def calendar_email(user)
    @user = user
    mail(to: @user.email, subject: 'Your Cogsmart To Do List')
  end
end

calendar_mailer_preview.rb:

class CalendarMailerPreview < ActionMailer::Preview

  def calendar_email
    CalendarMailer.calendar_email(User.first)
  end

end

calendar_email.html.erb:

<h1>Thanks @user.name for using Cogsmart, here's your calendar</h1>
