尝试根据邮递员的要求将数据集作为表格返回

Question

我想向邮递员索取所有书籍的表格作为退货，但我找不到办法做到这一点。非常感谢

这是我的书本模型：

class Book(models.Model):
    name = models.CharField(max_length=100)
    username = models.ForeignKey(User, on_delete=models.CASCADE)
    publication_date = models.DateField()
    publisher = models.ForeignKey(Publisher, on_delete=models.CASCADE)
    description = models.TextField()

    def __str__(self):
        return self.name

这是我的观点：

class AddBookAPIView(APIView):
    renderer_classes = [TemplateHTMLRenderer]
    template_name = 'book.html'

    @method_decorator(login_required(login_url='login/'))
    def post(self, request):
        book_serializer = BookSerializer(data=request.data)
        if book_serializer.is_valid():
            book_serializer.save()
            return redirect('home')

        return Response({'message': book_serializer.errors})

    @method_decorator(login_required(login_url='login/'))
    def get(self, request):
        book = Book()
        serializer = BookSerializer(book)
        return Response({'serializer': serializer, 'book': book})

Answer 1

尝试在

many=True

中使用

BookSerializer

并使用

Book.objects.all()

检索

Book

的所有实例，如下所示：

class AddBookAPIView(APIView):
    renderer_classes = [TemplateHTMLRenderer]
    template_name = 'book.html'

    @method_decorator(login_required(login_url='login/'))
    def post(self, request):
        book_serializer = BookSerializer(data=request.data)
        if book_serializer.is_valid():
            book_serializer.save()
            return redirect('home')

        return Response({'message': book_serializer.errors})

    @method_decorator(login_required(login_url='login/'))
    def get(self, request):
        book = Book.objects.all()
        serializer = BookSerializer(book, many=True)
        return Response({'serializer': serializer, 'book': book})
