Django发送基于日期的电子邮件提醒如何？

from django.core.management.base import BaseCommand
from django.core.mail import EmailMessage
from django.template.loader import render_to_string
from django.utils import timezone
from myapp.models import Reminder

class Command(BaseCommand):
    help = 'Send email reminders based on dates'

    def handle(self, *args, **options):
        current_date = timezone.now().date()
        reminders = Reminder.objects.filter(date=current_date)

        for reminder in reminders:
            subject = 'Reminder: {}'.format(reminder.title)
            to = [reminder.email]
            from_email = 'noreply@example.com'
            context = {'reminder': reminder}
            message = render_to_string('reminder_email.html', context)

            email = EmailMessage(subject, message, from_email, to)
            email.send()

            self.stdout.write(self.style.SUCCESS('Successfully sent reminder "{}" to {}'.format(reminder.title, reminder.email)))
