根据您的问题提供的信息，您的表单很可能无效，因此没有调用form.save()。

def add_questions(request):

    form = QuestionForm()

    if request.method == 'POST':
        form = QuestionForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect(reverse('users:question'))

    context = {
            'form': form
        }
    return render(request, 'pages/data-entry-tool/add-question.html', context)

这是一个修改后的视图功能，你可以试试。这里的区别在于，如果表单无效，将再次呈现相同的视图，但会显示表单中的任何错误。
