Question

我正在关注本教程about ajax and crud。本教程使用基于函数的视图方法，相反，我想使用基于类的视图，特别是对于此视图。

def book_create(request):
    data = dict()

    if request.method == 'POST':
        form = BookForm(request.POST)
        if form.is_valid():
            form.save()
            data['form_is_valid'] = True
            books = Book.objects.all()
            data['html_book_list'] = render_to_string('books/includes/partial_book_list.html', {
                'books': books
            })
        else:
            data['form_is_valid'] = False
    else:
        form = BookForm()

    context = {'form': form}
    data['html_form'] = render_to_string('books/includes/partial_book_create.html',
        context,
        request=request
    )
    return JsonResponse(data)

这是基于您的案例的基于类的视图的示例。

from django.views import View

class BookCreateView(View):

    def post(self, request):
        form = BookForm(request.POST)
        if form.is_valid():
            form.save()
            data['form_is_valid'] = True
            books = Book.objects.all()
            data['html_book_list'] = render_to_string('books/includes/partial_book_list.html', {
                'books': books
            })
        else:
            data['form_is_valid'] = False
        context = {'form': form}
        data['html_form'] = render_to_string('books/includes/partial_book_create.html',
            context,
            request=request
        )
        return JsonResponse(data)

    def get(self, request):
        data = dict()
        form = BookForm()
        context = {'form': form}
        data['html_form'] = render_to_string('books/includes/partial_book_create.html',
            context,
            request=request
        )
        return JsonResponse(data)

如何使用基于类的视图处理这个基于函数的视图？
