html - 如何解决我的视图文件中的值错误

Question

在我看来，谁能帮我解决这个问题。我已经被困了很长时间了。任何帮助将不胜感激。

我的观点.py

而且我不知道我的方法是否正确，但我只想保存原始 HTML 表单中的数据，因为我必须使用 java 脚本进行一些前端验证。

from django.shortcuts import render
from .models import TimesheetDetails

# Create your views here.
def create_timesheet_view(request):
    if request.method=="POST":
        if(request.POST.get('dateToday') and request.POST.get('dayToday') and request.POST.get('startTime')
            and request.POST.get('endTime')and request.POST.get('breakTime')and request.POST.get('normalTime')
            and request.POST.get('overTime')and request.POST.get('holidayTime')and request.POST.get('weekType')
            and request.POST.get('attendance')and request.POST.get('content')):
            post = TimesheetDetails()
            post.date = request.POST.get('dateToday')
            post.day = request.POST.get('day_today')
            post.startTime = request.POST.get('startTime')
            post.endTime = request.POST.get('endTime')
            post.breakTime = request.POST.get('breakTime')
            post.normalTime = request.POST.get('normalTime')
            post.overTime = request.POST.get('overTime')
            post.holidayTime = request.POST.get('holidayTime')
            post.weekType = request.POST.get('weekType')
            post.attendance = request.POST.get('attendance')
            post.content = request.POST.get('content')
            if post.is_valid():
                try:    
                    post.save()
                    return render(request,'timesheet/view_timesheet.html')
                except :
                    pass
    else:
        return render(request,'timesheet/create_timesheet.html')
def view_timesheet(request):
    return render(request,"timesheet/view_timesheet.html")

我的模型.py

类 TimesheetDetails(models.Model):

 date = models.CharField(max_length = 10)
    day = models.CharField(max_length = 10)
    startTime = models.CharField(max_length =10)
    endTime = models.CharField(max_length =10)
    breakTime = models.CharField(max_length=3)
    normalTime = models.CharField(max_length=10)
    overTime = models.CharField(max_length = 10)
    holidayTime = models.CharField(max_length = 10)
    weekType = models.CharField( max_length = 10)
    attendance = models.CharField( max_length = 10)
    content = models.TextField( max_length = 300)

最后是我的 HTML 页面

欢迎来到 SO :)

返回时您没有返回post.is_valid()HttpResponse False。
