我有个问题。
堆栈：Django-Rest-Framework + Djongo + Mongodb。
问题：插入错误数组数据

//models.py

from django.db import models
from djongo import models as djongoModels

class House(models.Model):
    house_id = models.CharField(max_length=256)

    class Meta:
        abstract = True

class Users(models.Model):
    _id = djongoModels.ObjectIdField()
    email = djongoModels.CharField(max_length=256)
    name = djongoModels.CharField(max_length=256)
    house = djongoModels.ArrayField(
        model_container=House
    )

    class Meta:
        db_table = "drf_users"

//serializers.py
from .models import Users, Houses
from rest_framework import serializers

class InsertUserSerializers(serializers.ModelSerializer):
    email = serializers.CharField(required=True)
    name = serializers.CharField(required=True)
    house = serializers.ListField(child=serializers.CharField())

    class Meta:
        model = Users
        fields = ('email', 'name', 'house')

//views.py
from .models import Users
from .serializers import InsertUserSerializers

class UsersViewSet(viewsets.ModelViewSet):
    queryset = Users.objects.all()
    serializer_class = InsertUserSerializers
    permission_classes = [AllowAny]

//request.http
POST http://<domain>/drf/house/ HTTP/1.1
Content-Type: application/json

{
    "email": "test6@stay.co.kr",
    "name": "test6",
    "house": ["SEOU-2023-1023-0002","GYOU-2023-1022-0001"]
}

我想要一个最终的数据库值。 enter image description here

这是序列化程序的问题吗？或者 Djongo 问题。
如果删除序列化程序房屋数组字段，则不会出错。
我的源代码有什么问题。请帮我。

[自行解决]
这是模型和值之间的问题。

//ArrayField: Only available {key:value} 
//models.py
class House(models.Model):
    house_id = models.CharField(max_length=256)

class Users(models.Model):
    ...
    house = djongoModels.ArrayField(
        model_container=House
    )

//request value
"house": [{"house_id":"SEOU-2023-1023-0002"},{"house_id":"GYOU-2023-1022-0001"}]

//JSONField or CharField: Available {value, value...} 
//models.py
class Users(models.Model):
    ...
   #house = djongoModels.CharField(max_length=256) <= exists max_length's problem  
    house = djongoModels.JSONField()

//request value
"house": ["SEOU-2023-1023-0002","GYOU-2023-1022-0001"]
