Question

我正在使用Django和Python 3.7。我在每个环境中都有不同的数据库配置，因此我想创建仅根据环境导入数据库配置的设置。我有这个目录...

mainpage_project/settings

这些文件位于

中。 “ base.py”包含我希望包含的设置，而与加载的环境无关...

(venv) localhost:mainpage_project davea$ ls mainpage_project/settings
__pycache__  base.py  dev.py  prod.py  test.py

我在mainpage_project / settings / test.py文件中有此文件...

from mainpage.base import *

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

但是当我运行测试文件时，出现错误，抱怨它无法执行导入的第一行“ from mainpage.base import *” ...

如何正确引用我的设置？

Answer 1

我不确定您从哪里获得mainpage的{{1}}部分。

您可以将其更改为正确的绝对导入：

from mainpage.base import *

或相对导入：

from mainpage_project.settings.base import *

注意，绝对进口要求from .base import *是在PATH。

如何从运行单元测试中引用设置文件？
