Import file from another app in Django 1.10

I'm trying to import a file from another app, and I get this error:

Unhandled exception in thread started by <function wrapper at 0x7fe7bc281d70>

from apps.website.managers import GenericManager
ImportError: No module named website.managers


INSTALLED APPS in settings.py

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


All my apps are in apps folder. I have an app called "maquina". And this is its 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):
...


I created a file called managers.py from another app called website

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


I notice that the error is this line:

from apps.website.managers import GenericManager


This is my code structure:

How is the correct way to import a file from another app? Thanks!

Answer

in setting try to add this line after BASE_DIR sys.path.insert(0, os.path.join(BASE_DIR, 'apps')) dont forget import os import sys
