Question

我正在尝试重构我的项目以匹配最新的两本Django书（Django 1.11）中的建议。

完成重组后，我的应用程序无法导入。

settings.py摘录：

...
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',
] ...

运行时

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

我明白了：

ImportError: No module named 'dash'

secureDash.dash.apps.DashConfig：

from django.apps import AppConfig


class DashConfig(AppConfig):
    name = 'dash'

Answer 1

在secureDash.dash.apps.DashConfig中使用secureDash.dash替换INSTALLED_APPS应修复此问题。
