Question

我有一个模特：

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

在视图中，我想查找在给定日期范围内创建的客户。比方说7天。

代码如下：

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()])})

给出：

无法将关键字'date'解析为字段。选择是：地址，创建，电子邮件，姓名，电话号码，SendEmail，SendSms，姓氏，身份证，宠物

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)})

但是这给了：

语法无效

错误。如何为此过滤日期？

Answer 1

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

顺便说一句，最好使用lowercase名称创建模型字段，模板名称，目录，函数等。

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})

您可能需要查看有关Python中命名约定规则的style guide。
