配置不当：本地设置和设置的 Django 问题

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. "

我不知道为什么我的settings.py最后会有这个

try:
    from local_settings import *
except:
    pass

而且只有我的local_settings.py有这个

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

是的，在同一个目录中。我正在使用python3，Windows 10

编辑

修复一下

本地设置

import os

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

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

DEBUG = True

如果您将其部署到 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 *
