我正在尝试从另一个应用程序导入文件，但出现此错误：

在 settings.py 中安装的应用程序
SYSTEM_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',

PROJECT_APPS = [
'apps.website',
'apps.maquina',
]
INSTALLED_APPS = SYSTEM_APPS + PROJECT_APPS
我所有的应用程序都在应用程序文件夹中。我有一个名为“maquina”的应用程序。这是它的modals.py
from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import User
from apps.website.managers import GenericManager
from .utils import path_and_rename
class Fabricante(models.Model):
...
我从另一个名为website的应用程序中创建了一个名为manager.py的文件
from django.db import models
class GenericManager(models.Manager):
def get_or_none(self, *args, **kwargs):
try:
return self.get(*args, **kwargs)
except self.model.DoesNotExist:
return None
except self.model.MultipleObjectsReturned:
return None
我注意到错误是这一行：
from apps.website.managers import GenericManager
这是我的代码结构：
从另一个应用程序导入文件的正确方法是什么？谢谢！
