django用serializers.ModelSerializer方式序列化

django用serializers.ModelSerializer方式序列化

1.在上一篇的基础上,在users/Serializer.py中,写book的ModelSerializer序列化类:

class BookModelSerializer(serializers.ModelSerializer):
    class Meta():
        model=Book
        fields="__all__"

如果不全都序列化,只需要修改fields=(‘字段’)
2.BookModelSerializer的API视图类:

class BookAPIView2(APIView):
    def get(self,request,format=None):
        APIKey = self.request.query_params.get('apikey', 0)
        developer = UserProfile.objects.filter(APIKey=APIKey).first()
        if developer:
            balance = developer.money
            if balance > 0:
                isbn = self.request.query_params.get('isbn', 0)
                books = Book.objects.filter(isbn=int(isbn))
                books_serializer = BookModelSerializer(books, many=True)
                developer.money -= 1
                developer.save()
                return Response(books_serializer.data)
            else:
                return Response('兄弟,又到需要充钱的时候!')
        else:
            return Response('查无此人啊!')

3.配置urls.py
