我喜欢把我的django应用程序拆分到多个文件夹中，就像图中一样。

示例

Bank
---views
---urls
---models
---serializer

Currency
---views
---urls
---models
---serializer

我把__init.py__文件放在每个文件夹里，这里是银行文件夹里的init文件`

from .models import BimaCoreBank`

这里是models.py for bank文件夹

from core.abstract.models import AbstractModel
from core.country.models import BimaCoreCountry
from core.state.models import BimaCoreState

class BimaCoreBank(AbstractModel):
    name = models.CharField(max_length=128, blank=False, unique=True)
    street = models.CharField(max_length=256, blank=True, null=True)
    street2 = models.CharField(max_length=256, blank=True, null=True)
    zip = models.CharField(max_length=16, blank=True, null=True)
    city = models.CharField(max_length=16, blank=True, null=True)
    state = models.ForeignKey(
        BimaCoreState, on_delete=models.PROTECT)
    country = models.ForeignKey(
        BimaCoreCountry, on_delete=models.PROTECT)
    email = models.EmailField(blank=True, null=True)
    active = models.BooleanField(default=True)
    bic = models.CharField(max_length=16, blank=True, null=True)

    def __str__(self) -> str:
        return self.name

    class Meta:
        ordering = ['name']
        permissions = []
        app_label = "BimaCoreBank"

这里是银行文件夹中的urls.py文件
从rest_framework导入路由器
从core.bank.views导入BimaCoreBankViewSet

router = routers.DefaultRouter()

app_name = 'BimaCoreBank'

urlpatterns = [
    router.register(r'bank', BimaCoreBankViewSet, basename='bank'),
]

每个文件夹都是一样的，只是我改了类名
现在，在core文件夹（包含所有子文件夹的app文件夹）中的__init.py__文件中

from . import bank
from . import country
from . import currency
from . import state

int的urls.py在核心文件夹我有这个

from django.urls import path, include

app_name = 'core'

urlpatterns = [
    path('currency/', include('currency.urls.py')),
    path('country/', include('country.urls.py')),
    path('state/', include('state.urls.py')),
    path('bank/', include('bank.urls.py'))
]

最后在app文件夹（我的项目的主文件夹）中，我在www.example.com中有这个urls.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/schema/', SpectacularAPIView.as_view(), name='api-schema'),
    path(
        'api/docs/',
        SpectacularSwaggerView.as_view(url_name='api-schema'),
        name='api-docs',
    ),
    path('api/user/', include('user.urls')),
    path('api/core/', include('core.urls'))

]

但没有成功，
第一次我添加app_label在meta class foreach文件夹（银行，货币...）
然后我在urls.py文件中添加了'app_name'，它也不起作用
现在的错误消息是这样的

我的问题是，是否可以像我一样将一个django应用程序拆分到多个文件夹中？如果不能，如何拆分一个django应用程序，因为我不喜欢在同一个文件中有多个模型类
