Signature de la méthode from_envvar

def from_envvar(self, variable_name: str, silent: bool = False) -> bool 

Description

from_envvar.__doc__

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'])

        :param variable_name: name of the environment variable
        :param silent: set to ``True`` if you want silent failure for missing
                       files.
        :return: ``True`` if the file was loaded successfully.
