Django項目重組：無法導入應用程序

我試圖重構我的項目，以匹配Django最新的兩本書（適用於Django 1.11）中的建議。Django項目重組：無法導入應用程序

完成重組後，我的應用程序無法導入。

settings.py摘錄：

... 
import os 

# Build paths inside the project like this: os.path.join(BASE_DIR, ...) 
BASE_DIR = os.path.dirname(os.path.dirname(
    os.path.dirname(os.path.abspath(__file__)))) 
ENV_PATH = os.path.abspath(os.path.dirname(__file__)) 

# SECURITY WARNING: don't run with debug turned on in production! 
DEBUG = True 

# Application definition 

INSTALLED_APPS = [ 
    'secureDash.dash.apps.DashConfig', 
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    # 'django_static_jquery', 
    # 'bootstrap3', 
] ...

當運行

python3 manage.py runserver --settings=config.settings.settings

我得到：

ImportError: No module named 'dash'

secureDash.dash.apps.DashConfig：

from django.apps import AppConfig 


class DashConfig(AppConfig): 
    name = 'dash'

您是否嘗試用'secureDash.dash'替換'secureDash.dash.apps.DashConfig'？ –

沒有。這工作雖然。你能幫我理解爲什麼這有效嗎？ – brewcrazy

'django'尋找你的'apps'根目錄。所以在這種情況下，它是'secureDash/dash /'文件夾。之後，它會查找'views.py'和'urls.py'來配置它。 –

替換secureDash.dash.apps.DashConfig與secureDash.dash在INSTALLED_APPS應該修復它。
