下午好！我正在嘗試解決這個問題，但我自己解決它的所有嘗試只會導致將 def 更改為 class，這無濟于事。你能告訴我問題是什么嗎？views.pyfrom django.core.mail import send_mail, BadHeaderErrorfrom django.shortcuts import render, redirectfrom django.http import HttpResponse, HttpResponseRedirectfrom .models import Formdef FormListView(request):    if request.method == 'GET':        form = FormListView()    else:        form = FormListView(request.POST)        if form.is_valid():            name = form.cleaned_data['name']            surname = form.cleaned_data['surname']            email = form.cleaned_data['email']            try:                send_mail(name, surname, email, ['[email protected]'])            except BadHeaderError:                return HttpResponse('Invalid')            return redirect('success')    return render(request, "index.html", {'form': form})def Success(request):    return HttpResponse('Success!')urls.pyfrom django.urls import pathfrom .views import FormListViewurlpatterns = [    path('', FormListView.as_view(), name = 'home'),    path('success/', Success.as_view(), name = 'success')]是錯的：  File "/home/user/Portfolio/web_project/web_page/urls.py", line 5, in <module>    path('', FormListView.as_view(), name = 'home'),AttributeError: 'function' object has no attribute 'as_view'
