from book.models import Book


class BookSerializer(serializers.ModelSerializer):
    class Meta:
        model = Book
        fields = ('title', 'author','summary', 'isbn')```



** Create your views here :api/views.py**


```from django.shortcuts import render
from rest_framework import generics

from book.models import Book
from .serializers import BookSerializer


class BookAPIView(generics.ListAPIView):
    queryset = Book.objects.all()
    serializer_class = BookSerializer```


**# api/urls.py**
```from django.urls import path
from .views import BookAPIView

urlpatterns = [
    path('', BookAPIView.as_view())
]```

我在升级到 django 4.0 时也遇到了同样的问题。将rest_framework升级到最新版本（https://github.com/encode/django-rest-framework/releases） 修复。
