python - 基于django更新函数的多个模型视图

Question

我有一个父模型和两个子模型，我创建了一个视图来将多个子添加到一个父级，但是我对为所有子级的父级创建更新视图感到困惑

这是创建多个子views.py的形式

def create_day_view(request,pk):
    mydate = get_object_or_404(MyDate,pk=pk)
    if request.method == 'POST':
        length = request.POST.get('length')
        sof_zman_1 = request.POST.get('sof_zman_1')
        sof_zman_2 = request.POST.get('sof_zman_2')
        sof_zman_tefila = request.POST.get('sof_zman_tefila')
        ad_image = request.POST.get('ad_image')

        day_details = MyDateDetails.objects.create(
            date = mydate,
            sof_zman_1 = sof_zman_1,
            sof_zman_2 = sof_zman_2,
            sof_zman_tefila = sof_zman_tefila,
            ad_image = ad_image,
        )
        
        for file_num in range(0, int(length)):
            Image.objects.create(
                date = mydate,
                image = request.FILES.get(f'images{file_num}')
            )

    context = {'mydate': mydate}
    return render(request, 'luach/create_day.html',context=context)

我正在共享模板，以便您了解表单的工作原理 create_day.html

{% extends 'luach/base.html' %}
