Python3.x Django 5.0.2和django_rest_framework

嗨，伙计们，我有问题从postgresql用django读取SQL数据. 我用www.example.com inspectdb创建了我的模型 命令来自现有数据库.

我的模型:

from django.db import models

class Regions(models.Model):
    code = models.CharField(unique=True, max_length=4)
    capital = models.CharField(max_length=10)
    name = models.TextField(unique=True)

    class Meta:
        managed = False
        db_table = "regions"

我的序列化器:

from rest_framework import serializers


class RegionsSerializer(serializers.ModelSerializer):
    class Meta:
        model = "france.models.Regions"
        fields = "__all__"

帖子主题:Re:Колибри

from rest_framework import viewsets
from rest_framework.response import Response
from .models import Regions
from .serializers import RegionsSerializer


class RegionsView(viewsets.ViewSet):
    def list(self, request):
        regions = Regions.objects.all()
        serializer = RegionsSerializer(regions, many=True)
        return Response(serializer.data)

我得到的错误:
