Question

基本上我需要实现以下目标：当用户输入开始日期和结束日期时，我应该能够在表格的任一字段中自动填充天数（不包括周六，周日和节假日）。在数据库级别，我已经准备好表和查询来计算此内容。如何在Django中加入相同的内容？

我有请假申请和三个文件： models.py，views.py，forms.py和Leave.html文件

class Leaves(models.Model):
    leaveID = models.AutoField(primary_key=True)
    fromDate = models.DateField()
    toDate = models.DateField()
    leaveType=models.CharField(max_length=20)
    noofDays = models.IntegerField(blank=True,null=True)
    createdBy = models.CharField(max_length=30)
    createdAt = models.DateTimeField(default=datetime.datetime.now, null=True, blank=True)
    updatedAt = models.DateTimeField(default=datetime.datetime.now, null=True, blank=True)


def leave(request):
    context = {'form': Leaves}
    if request.method=='POST':
        form = LeaveForm(request.POST)

        if form.is_valid():
            leaveID=request.POST.get('leaveID')
            fromDate=request.POST.get('fromDates')
            toDate=request.POST.get('toDate')
            leaveType = request.POST.get('leaveType')
            createdBy = User.objects.get(username=request.user.username)
            noofDays = Dim_Date.objects.raw('select count(distinct calendarDate) from Dim_Date where isWeekday=1 and isHoliday<>1')
            form.save()

            return render(request,'leave/leaveconfirmation.html')
        else:
            return render(request,'leave/leave.html')
    else:
        return render(request,'leave/leave.html',context)

我应该能够根据表单中给出的from_date和to_date自动填充字段。（后端逻辑已准备就绪）请让我知道如何将其集成到Django中。

根据Django中的数据库计算自动填充表单中的字段
