一、准备工作：首先定义好model以及视图类相关信息

class Book(models.Model):
   name = models.CharField(max_length=32)
   pub_num = models.IntegerField(default=10)
   salary_num = models.IntegerField(default=100)
   
   def __str__(self):
      return self.name

class CheckView(viewsets.GenericViewSet, mixins.ListModelMixin):
   queryset = models.Book.objects.all()
   serializer_class = BookSerializer

   def get(self, request):
      res = self.serializer_class(self.queryset, many=True)
      return Response(res.data)

class BookSerializer(serializers.ModelSerializer):
   authors_info = serializers.SerializerMethodField(read_only=True)
   
   def get_authors_info(self, obj):
      return [{‘id‘: author.id, ‘name‘: author.name} for author in obj.authors.all()]
   
   class Meta:
      fields = ‘__all__‘
      model = models.Book
