使用多对多关系将ajax数据传递给Django模型

Question

我已经在这方面工作了一段时间，我感到很困惑。我一直在看文件

https://www.django-rest-framework.org/api-guide/relations/#nested-relationships

但仍然无法理解这是如何运作的

如果有人能帮我解决这个错误，或者解释这是如何工作的，我会很高兴得到一些帮助。谢谢

我想要的是：

1. 将ajax发送到django rest框架api端点
2. 让django/DRF在postgreSQL数据库中保存多对多相关数据

我得到的是：

TypeError:会话（）获得意外的关键字参数“pose\u list”

型号.py

class Pose(models.Model):
    name = models.CharField(max_length=100, blank=False, default='')

    def __str__(self):
        return self.name

class SeshPoseList(models.Model):
    order = models.PositiveIntegerField()
    pose_fk = models.ForeignKey(Pose, on_delete=models.CASCADE)

class Session(models.Model):
    session_name = models.CharField(max_length=100, blank=False, default='')

    def __str__(self):
        return self.name

序列化程序.py

class PoseSerializer(serializers.ModelSerializer):
    
    class Meta:
        model = Pose
        fields = ('id', 'name')

class SeshPoseListSerializer(serializers.ModelSerializer):

    def create(self, validated_data):
        return Session.objects.create(**validated_data)

    class Meta:
        model = SeshPoseList
        fields = ['order', 'pose_fk']

class SessionSerializer(serializers.ModelSerializer):
    pose_list = SeshPoseListSerializer(many=True)

    def create(self, validated_data):
        return Session.objects.create(**validated_data)

    class Meta:
        model = Session
        fields = ('id', 'session_name', 'pose_list')

视图.py

@api_view(['GET', 'POST', 'PUT', 'DELETE'])
def session_list(request):
    if request.method == 'POST':
        seshSerializer = SessionSerializer(data=request.data)
        if seshSerializer.is_valid():
            seshSerializer.create(seshSerializer.validated_data)
            return Response(seshSerializer.data, status=status.HTTP_201_CREATED)
        print("sesh errors --->  ", seshSerializer.errors)
        return Response(seshSerializer.errors, status=status.HTTP_400_BAD_REQUEST)
