Flask应用程序的配置文件

我正在尝试创建一个文件，用于将我的配置设置存储在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"

这里的地方，我用它（地点：app/models.py）：

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

但是，我似乎得到这个启动应用程序时出错：

你没工作怎么对我很好，但是我没有配置SQLAlchemy的和我相当于你的应用程序目录是flaskdemo其中是一个包，因为我的项目结构如http://flask.pocoo.org/docs/0.10/patterns/packages/所示。我的项目位于https://goo.gl/SgFqz5。 – 2015-08-08 17:53:06

您的配置G文件应该是这样的：

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')
