flask.Config.from_envvar¶

Config.from_envvar(variable_name, silent=False)[source]¶

Loads a configuration from an environment variable pointing to a configuration file. This is basically just a shortcut with nicer error messages for this line of code:

app.config.from_pyfile(os.environ['YOURAPPLICATION_SETTINGS'])

Parameters:	variable_name – name of the environment variable silent – set to True if you want silent failure for missing files.
Returns:	bool. True if able to load config, False otherwise.
