在django中自动删除超过10天的数据

需求：比如过期10天的产品自动删除记录

posting_date = models.DateTimeField(auto_now_add=True)

# purge_old_data.py

from django.core.management.base import BaseCommand, CommandError
from cus_leads.models import CustomerLeads 
from datetime import datetime, timedelta

class Command(BaseCommand):
    help = 'Delete objects older than 10 days'

    def handle(self, *args, **options):
        CustomerLeads.objects.filter(posting_date__lte=datetime.now()-timedelta(days=10)).delete()
        self.stdout.write('Deleted objects older than 10 days')
