如何知道客户在Django新的付款日期到了？

from django.db import models

class Payment(models.Model):
    customer = models.ForeignKey('Customer', on_delete=models.CASCADE)
    payment_date = models.DateField()
    amount = models.DecimalField(max_digits=10, decimal_places=2)

from django.db import models

class Customer(models.Model):
    name = models.CharField(max_length=100)
    # other fields

from django.shortcuts import render
from datetime import date

def payment_status(request):
    customer = Customer.objects.get(id=1)  # 假设查询ID为1的客户
    latest_payment = Payment.objects.filter(customer=customer).latest('payment_date')
    
    if latest_payment.payment_date >= date.today():
        status = '已付款'
    else:
        status = '未付款'

    context = {'status': status}
    return render(request, 'payment_status.html', context)

<!-- payment_status.html -->
<p>付款状态: {{ status }}</p>
