Question

我是Python的新手，所以请耐心等待。

我正在尝试创建一个文件，用于将配置设置存储在Flask项目中。但是，当我尝试导入文件时，我似乎遇到了错误。

这是我的配置文件（位置：app/config.py）：

database_uri = 'something here'
secret_key = something here"

这就是我使用它的位置（位置：app/models.py）：

from app import config
...
app.config['SQLALCHEMY_DATABASE_URI'] = config.database_uri

但是，我在启动应用程序时似乎遇到了这个错误：

Answer 1

您的配置文件应如下所示：

SQLALCHEMY_DATABASE_URI = '<your-db-driver>://<user>:<pw>@<db-url>'
SECRET_KEY = '<your-very-secret-key>'

然后你可以这样做：

app = Flask(__name__)
app.config.from_object('config')

Flask应用程序的配置文件
