Question

我在python 3.5中使用django 1.11.5和windows 7。

我的设置文件夹包含base.py，mysql.py和sqlite.py

manage.py包含：

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "GuardianAngel.settings")

当我尝试python manage.py makemigrations时，我收到以下错误：

    raise ImproperlyConfigured("The SECRET_KEY setting must not be empty.")
django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

如果我将os.environ.setdefault更改为manage.py，请执行以下操作：

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "GuardianAngel.settings.base")

值得注意的是base.py包含SECRET_KEY之类的内容：

SECRET_KEY = 'i$778^0hplfwr_tgm$7p!azz61lkif6qz#-0_*k4o88tq6=7aw'

我没有收到此错误，我收到有关mysql的错误。

settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

你知道如何解决这个问题吗？

Answer 1

将其设为：

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "GuardianAngel.settings.base")

但在base.py中添加此内容：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', 
        'NAME': 'DB_NAME',
        'USER': 'DB_USERNAME',
        'PASSWORD': 'DB_PASSWORD',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}

或者更好的是，在GuardianAngel中创建另一个名为local_settings.py的文件并添加

from settings.base import *

然后添加上面提到的DATABASES。

Django：即使SECRET_KEY设置存在于设置中，它也不能为空
