Python 提交时未重置表格？

我有一个页面，其中有一个表单，一旦提交，表单将再次加载给下一个人。我从基于类的视图切换到基于函数的视图，因为我不得不渲染模态，我注意到，现在，由于我不再重定向到表单，它不会清除以前输入的数据。我如何在提交时清除表格

视图.py

def enter_exit_area(request):

    form = WarehouseForm(request.POST or None)
    enter_without_exit = None
    exit_without_enter = None

    if form.is_valid():
        emp_num = form.cleaned_data['employee_number']
        area = form.cleaned_data['work_area']
        station = form.cleaned_data['station_number']

        if 'enter_area' in request.POST:
            # Some rules to open modals/submit

            message = 'You have entered %(area)s' % {'area': area}
            if station is not None:
                message += ': %(station)s' % {'station': station}
            messages.success(request, message)

        elif 'leave_area' in request.POST:
           # more Rules

            message = 'You have exited %(area)s' % {'area': area}
            if station is not None:
                message += ': %(station)s' % {'station': station}
            messages.success(request, message)

    return render(request, "operations/enter_exit_area.html", {
        'form': form,
        'enter_without_exit': enter_without_exit,
        'exit_without_enter': exit_without_enter,
    })

class WarehouseForm(AppsModelForm):
    class Meta:
        model = EmployeeWorkAreaLog
        widgets = {
            'employee_number': ForeignKeyRawIdWidget(EmployeeWorkAreaLog._meta.get_field('employee_number').remote_field, site, attrs={'id':'employee_number_field'}),
        }
        fields = ('employee_number', 'work_area', 'station_number', 'edited_timestamp')

forms.py

def enter_exit_area(request):

    form = WarehouseForm(request.POST or None)
    enter_without_exit = None
    exit_without_enter = None

    if form.is_valid():
        emp_num = form.cleaned_data['employee_number']
        area = form.cleaned_data['work_area']
        station = form.cleaned_data['station_number']

        if 'enter_area' in request.POST:
            # Some rules to open modals/submit

            message = 'You have entered %(area)s' % {'area': area}
            if station is not None:
                message += ': %(station)s' % {'station': station}
            messages.success(request, message)

        elif 'leave_area' in request.POST:
           # more Rules

            message = 'You have exited %(area)s' % {'area': area}
            if station is not None:
                message += ': %(station)s' % {'station': station}
            messages.success(request, message)

    return render(request, "operations/enter_exit_area.html", {
        'form': form,
        'enter_without_exit': enter_without_exit,
        'exit_without_enter': exit_without_enter,
    })

class WarehouseForm(AppsModelForm):
    class Meta:
        model = EmployeeWorkAreaLog
        widgets = {
            'employee_number': ForeignKeyRawIdWidget(EmployeeWorkAreaLog._meta.get_field('employee_number').remote_field, site, attrs={'id':'employee_number_field'}),
        }
        fields = ('employee_number', 'work_area', 'station_number', 'edited_timestamp')

进入退出区域.html

使用if语句仍然会导致表单不清晰，而只保留

form=WarehouseForm（）

会导致表单不提交给数据库。我刚刚编辑了我的答案供您评论，请尝试此操作。
