在CalendarMailerPreview Rails Mailer Preview中找不到电子邮件“ email_calendar”

Question

I've created a basic mailer and am not able to see the preview using the following path: http://localhost:3000/rails/mailers/calendar_mailer/calendar_email

Here is my mailer, preview, and email body code:

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>
