print_settings
==============
:synopsis: Django management command similar to ``diffsettings`` but shows *selected* active Django settings or *all* if no args passed.
Introduction
------------
Django comes with a ``diffsettings`` command that shows how your project's
settings differ from the Django defaults. Sometimes it is useful to just see
the settings that are in effect for your project. This is particularly
true if you have a more complex system for settings than just a single
:file:`settings.py` file. For example, you might have settings files that
import other settings file, such as dev, test, and production settings files
that source a base settings file.
This command also supports dumping the data in a few different formats.
More Info
---------------
The simplest way to run it is with no arguments::
$ python manage.py print_settings
Some variations::
$ python manage.py print_settings --format=json
$ python manage.py print_settings --format=yaml # Requires PyYAML
$ python manage.py print_settings --format=pprint
$ python manage.py print_settings --format=text
$ python manage.py print_settings --format=value
Show just selected settings::
$ python manage.py print_settings DEBUG INSTALLED_APPS
$ python manage.py print_settings DEBUG INSTALLED_APPS --format=pprint
$ python manage.py print_settings INSTALLED_APPS --format=value
It is also possible to use shell-style wildcards::
$ python manage.py print_settings TIME*
$ python manage.py print_settings *_DIRS STATIC*
$ python manage.py print_settings INSTALLED_????
Yielding an error when a settings does not exist::
$ ./manage.py print_settings -f INSTALLED_APPZ
CommandError: INSTALLED_APPZ not found in settings.
For more info, take a look at the built-in help::
$ python manage.py print_settings --help
usage: manage.py print_settings [-h] [-f] [--format FORMAT] [--indent INDENT] [--version] [-v {0,1,2,3}]
[--settings SETTINGS] [--pythonpath PYTHONPATH] [--traceback] [--no-color]
