python - 如何查找给定日期范围内创建的对象？

Question

我有一个模型:

class Customer(models.Model):
    Name = models.TextField(blank=False)
    Surname = models.TextField(blank=False)
    PhoneNumber = models.TextField()
    Address = models.TextField()
    SendSms = models.BooleanField(default=True)
    SendEmail = models.BooleanField(default=True)
    Email = models.TextField()
    Created = models.DateField(auto_now_add=True)

    @classmethod
    def create(cls, name, surname, phoneNumber, address , sendSms, sendEmail, email):
        customer = cls(Name=name, Surname=surname, PhoneNumber=phoneNumber
                        , Address=address, SendSms=sendSms, SendEmail=sendEmail
                        , Email=email)
        customer.save()
        return customer

在 View 中，我想查找在给定日期范围内创建的客户。就说7天吧。

下面的代码:

def RecentCustomers(request):
    return render_to_response("Customer/AllCustomers.html", {
        "customers": Customer.objects.filter(
            date__range=[datetime.date.today() - datetime.timedelta(days=7), datetime.date.today()])})

给予:

Cannot resolve keyword 'date' into field. Choices are: Address, Created, Email, Name, PhoneNumber, SendEmail, SendSms, Surname, id, pet

错误。我也尝试过:

def RecentCustomers(request):
    return render_to_response("Customer/AllCustomers.html", {
        "customers": Customer.objects.filter(Created >= datetime.date.today() - datetime.timedelta(days=7)})

但是这给出了:

invalid syntax

错误。我如何过滤日期？

Answer 1

Customer.objects.filter(Created__gte=datetime.date.today() - datetime.timedelta(days=7))

顺便说一下，创建模型字段、模板名称、目录、函数等时最好始终使用小写名称。

from django.shortcuts import render

def recent_customers(request):
    customers = Customer.objects.filter(created__gte=datetime.date.today() - datetime.timedelta(days=7))
    return render(request, "customer/all_customers.html", {"customers": customers})
