如何在Django根据特定的天数进行余额挂载

from django.db import models

class User(models.Model):
    balance = models.DecimalField(max_digits=10, decimal_places=2, default=0.00)

from django.core.management.base import BaseCommand
from datetime import timedelta
from myapp.models import User

class Command(BaseCommand):
    help = 'Mount balance for users based on specific days'

    def handle(self, *args, **options):
        # 获取特定天数的用户
        users = User.objects.filter(specific_days=30)

        # 对每个用户进行余额挂载操作
        for user in users:
            user.balance += 100.00  # 假设挂载金额为100.00
            user.save()

INSTALLED_APPS = [
    ...
    'crontab',
    ...
]

CRONJOBS = [
    ('0 0 * * *', 'myapp.management.commands.mount_balance')
]

python manage.py crontab add
