"""Works exactly like a dict but provides ways to fill it from files
|
|
or special dictionaries. There are two common patterns to populate the
|
|
config.
|
|
|
|
Either you can fill the config from a config file::
|
|
|
|
app.config.from_pyfile('yourconfig.cfg')
|
|
|
|
Or alternatively you can define the configuration options in the
|
|
module that calls :meth:`from_object` or provide an import path to
|
|
a module that should be loaded. It is also possible to tell it to
|
|
use the same module and with that provide the configuration values
|
|
just before the call::
|
|
|
|
DEBUG = True
|
|
SECRET_KEY = 'development key'
|
|
app.config.from_object(__name__)
|
|
|
|
In both cases (loading from any Python file or loading from modules),
|
|
only uppercase keys are added to the config. This makes it possible to use
|
|
lowercase values in the config file for temporary values that are not added
|
|
to the config or to define the config keys in the same file that implements
|
|
the application.
|
|
|
|
Probably the most interesting way to load configurations is from an
|
|
environment variable pointing to a file::
|
|
|
|
app.config.from_envvar('YOURAPPLICATION_SETTINGS')
|
|
|
|
In this case before launching the application you have to set this
|
|
environment variable to the file you want to use. On Linux and OS X
|
|
use the export statement::
|
|
|
|
export YOURAPPLICATION_SETTINGS='/path/to/config/file'
|
|
|
|
On windows use `set` instead.
|
|
|
|
:param root_path: path to which files are read relative from. When the

config object is created by the application, this is

Objects are usually either modules or classes. :meth:`from_object`
