更多的pdf文件保存在不同日期的表格中，如何在fromdate和todate之间过滤pdf文件。

如何在日期之间过滤并列出 pdf 文件。

views.py

def select_date(request):
    client = Client.objects.all()
    process = Client_Process.objects.all()
    pdf = Client_files.objects.all()
    today = date.today()
    yesterday = today - timedelta(days = 1)
    print(today)
    print(yesterday)
    if request.method == "POST":
        fromdate = request.POST.get('fromdate')
        todate = request.POST.get('todate')
        user = Client_files.objects.filter(Date__range=(fromdate,todate))
        print(user)
    return render(request,'select_date.html', {'pdf':pdf,'client':client,'process':process})


models.py

class Client_files(models.Model):
    Date = models.DateTimeField(default=datetime.now, blank=True)
    client = models.ForeignKey(Client, on_delete=models.CASCADE,null=True)
    client_process = models.ForeignKey(Client_Process, on_delete=models.CASCADE,null=True)
    File_Name = models.FileField()
    Pages = models.IntegerField(null=True)
    Count = models.IntegerField(null=True)
    Status = models.BooleanField(default = False)

    class Meta:
        db_table : 'client_files'

【解决方案1】：

您应该使用__date lookup [Django-doc]，首先将日期时间转换为日期：

def select_date(request):
    client = Client.objects.all()
    process = Client_Process.objects.all()
    pdf = Client_files.objects.all()
    today = date.today()
    yesterday = today - timedelta(days = 1)
    print(today)
    print(yesterday)
    if request.method == "POST":
        fromdate = request.POST.get('fromdate')
        todate = request.POST.get('todate')
        pdf = Client_files.objects.filter(Date__date__range=(fromdate, todate))
        print(pdf)
    return render(request,'select_date.html', {'pdf':pdf,'client':client,'process':process})

通常，当您过滤项目时，您会将参数作为 GET 参数传递到 GET 请求中。 POST 请求通常会更改数据。
