Question

我正在尝试为django项目运行一个简单的测试，并将它们分成两个文件，因为这是一个很好的做法，但是，这总是给我一个错误

ImproperlyConfigured("settings.DATABASES is improperly configured. "

我不知道为什么我最终在我的settings.py

中有这个

try:
    from local_settings import *
except:
    pass

并且仅在local_settings.py

中有此内容

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

并且是的，在同一目录中。我正在使用python3，windows 10

修改

修复此问题

LOCAL_SETTINGS

import os

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'db.sqlite3',
    }
}

DEBUG = True

如果将此部署到heroku

，请将其添加到设置的末尾

import dj_database_url
DATABASES = {'default': dj_database_url.config()}

DEBUG = False

ALLOWED_HOSTS = ['*']

try:
    from .local_settings import *
except ImportError:
    pass

Answer 1

在Python 3中，相对导入应该是

from .local_settings import *

不正确的配置：Django与local_settings和设置有关
