This Django reusable app implements a base ``SettingsModel`` class to allow settings to
be edited and saved in the database. For any particular project, you probably want to
customize which settings are exposed, so while there is a ``Settings`` example
implementation that you can use, the abstract model ``SettingsModel`` can be used to
construct your own settings model(s), and things like webserver restarts are handled in
the abstract model class.

**The Problem**: Sometimes you want to build an app that can be managed by
non-developers, and things like timezone, hostname, or SMTP settings may need to be
editable from the UI.

**The Solution**: This app implements a base ``SettingsModel`` class that allows you to
expose settings to a user interface via the database. It writes these stub settings to
separate files which you try/include at the end of your main settings file. This way
you have sensible defaults, but when the user created/edits a model file in the UI,
those settings override. There is a mechanism to touch the ``wsgi.py``/``manage.py``
files when saving, so the only thing left to do is either configure your web server to
watch those files and reboot when they are touched, or use a tool like ``incrond`` to
watch those files and trigger your webserver to reboot when they are touched.


How to Use
==========

.. code-block:: shell

    $ pip install django-settings-model


You can use the builtin ``Settings`` model by including this app (``settings_model``) in
your ``INSTALLED_APPS`` and running migrations, or you can create your own custom
settings model, inheriting from ``settings_model.base.SettingsModel``. If you want to
build a custom settings Model, use the ``Settings`` model as a reference implementation.

For the included ``Settings`` model, you need to add the following to the end of your
``settings.py`` file:

.. code-block:: python

    try:
        from .model_settings import *
    except:
        pass


If you create a custom Settings model, then ensure you set the ``__settings_filename__``
appropriately (avoid conflicts with other settings models), and ensure you call its
``.init()`` class method in the application's ``AppConfig.ready()`` method. This will
update the settings with the true values (and optionally create an initial settings
model instance) on startup.


Settings
--------

- ``SETTINGS_MODEL_REBOOT_FILES`` (default ``[]``): This is a list of files that should
  be touched when the settings model is saved to signal to the webserver to reboot. If
  it is falsy, then the system will try to find and touch the file
  ``BASE_DIR/manage.py`` and the ``wsgi.py`` file defined by ``WSGI_APPLICATION``.
