Overview
|
|
========
|
|
|
|
The app uses a global :term:`config object` to keep track of its
|
|
:term:`config settings<config setting>`. See also :doc:`object`.
|
|
|
|
The app must call :func:`~wuttjamaican.conf.make_config()` during
|
|
startup to obtain the config object.
|
|
|
|
Values come (mostly) from :term:`config files<config file>` and/or the
|
|
:term:`settings table`. For more about those see:
|
|
|
|
* :doc:`settings`
|
|
* :doc:`files`
|
|
* :doc:`table`
|
|
|
|
Values are always strings in their raw format, as returned by
|
|
:meth:`~wuttjamaican.conf.WuttaConfig.get()`. But the config object
|
|
also has methods to coerce values to various types, e.g.:
|
|
|
|
* :meth:`~wuttjamaican.conf.WuttaConfig.get_bool()`
|
|
* :meth:`~wuttjamaican.conf.WuttaConfig.get_int()`
|
|
* :meth:`~wuttjamaican.conf.WuttaConfig.get_list()`
|
|
|
|
The config object is also responsible for creating the :term:`app
|
|
handler`::
|
|
|
|
from wuttjamaican.conf import make_config
|
|
|
|
config = make_config()
|
|
app = config.get_app()
|
|
|
|
if config.get_bool('foo.bar'):
|
|
print('YES for foo.bar')
|
|
else:
|
|
print('NO for foo.bar')
|
|
|
|
with app.short_session() as session:
|
|
print(session.bind)
