ruby-on-rails - 未定义的局部变量或方法`hospital_booking

Question

我有以下内容，它应该做的是在每个月的 18 日生成一份报告，这是应该做的。刚注意到一个小问题。我收到以下错误

undefined local variable or method hospital_booking

这还指向以下几点：

 app/models/hospital_booking.rb:30:in `send_overtime_mail'
  app/controllers/hospital_bookings_controller.rb:11:in `index'

我确定我的设置是正确的。如果有人可以帮我解决我搞砸的地方，谢谢。

医院预订

  def self.send_overtime_mail(user, bookings)
    OvertimeMailer.overtime_pdf(user, hospital_booking).deliver
   end 

调度器.rake

desc 'Send hospital bookings overtime report'
task :overtime_report => :environment do
  if Date.today.day == 18
    bookings = HospitalBooking.where(:day => Date.today.beginning_of_month..Date.today.end_of_month)
    user = User.where(:roles => :administrator).first
    OvertimeMailer.overtime_pdf(user, hospital_bookings).deliver
  end
end 

Answer 1

send_overtime_mail将参数转换为bookings变量，然后在方法hospital_booking内部使用。

def self.send_overtime_mail(user, bookings)
  OvertimeMailer.overtime_pdf(user, bookings).deliver
end

应该管用。
