I need to load configuration from multiple files. I use the code below to load one file. Should I use it repeatedly? How do I load multiple configs?

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

推荐答案

您可以根据需要加载配置，唯一的要求是它必须以 app.config 结尾. from_object 只是一种帮助方法，用于您的配置是否位于可导入的Python文件中，例如示例中的默认设置.还有其他帮助程序，或者您可以将 app.config 当作字典并根据需要设置值.

You can load config however you want, the only requirement is that it ends up in app.config. from_object is just a helper method for if your config is in an importable Python file, such as the default settings in your example. There are other helpers as well, or you can just treat app.config as a dict and set values however you want.

覆盖默认设置的标准方法是先加载它们，然后从实例文件夹中加载本地设置.

The standard method for overriding default settings is to load them and then load local settings from the instance folder.

app = Flask(__name__, instance_relative_config=True)
app.config.from_object('myapp.default_settings')
app.config.from_pyfile('local_settings.py', silent=True)

这会将实例文件夹中的 local_settings.py 加载到配置中，并忽略该文件是否不存在.

This will load local_settings.py in the instance folder into the config, and ignore if the file doesn't exist.

myproject/
    myapp/
        __init__.py
        default_settings.py
    instance/
        local_settings.py

通过导入应用程序在需要的地方访问配置.

Access the config wherever you need it by importing the app.

from myapp import app
my_value = app.config['my_key']
