Easy app-specific settings for Django

Project description

django-easysettings

Build status Coverage status

Easy app-specific settings for Django apps.

Provides a method for using a declarative class for an app’s default settings. The instance of this class can be used to access all project settings in place of django.conf.settings.

Installation

To install, run: pip install django-easysettings

Usage

Create a conf.py file within your app’s directory, adding attributes for the default values of your app-specific settings. They will be overridden by any project setting that is provided.

For example:

from easysettings.app import AppSettings


class Settings(AppSettings):
    MYAPP_FRUIT = 'Apple'


settings = Settings()

Then in your app, rather than from django.conf import settings, use from myapp.conf import settings. For example:

from myapp.conf import settings


def dashboard(request):
    context = {}
    context['fruit'] = settings.MYAPP_FRUIT
    if settings.DEBUG:
        context['debug_mode'] = True
    # ...

Dictionaries

A common pattern is to use a dictionary as a namespace for all an app’s settings, such as settings.MYAPP['settings'].

Easy-settings handles this fine, overriding any keys provided in the project while still having access to the default app settings keys.

You can also use a subclass of an AppSettings class to set up a dictionary.

from easysettings.apps import AppSettings


class MyAppSettings(AppSettings):
    """
    MyApp settings
    """
    #: Preferred fruit
    FRUIT = 'Apple'
    #: Preferred drink
    DRINK = 'Water'


class Settings(AppSettings):
    MYAPP = MyAppSettings


settings = Settings()

Legacy Usage

If previously your app used a common prefix (like MYAPP_) you can still support projects that still use these stand-alone legacy settings while moving to a MYAPP dictionary for your settings.

from easysettings.legacy import LegacyAppSettings


class Settings(LegacyAppSettings):
    MYAPP = {'FRUIT': 'Apple'}


settings = Settings()

If a project uses settings like MYAPP_FRUIT = 'Banana' they will continue to work. As soon as a project switches to MYAPP, any MYAPP_* settings will be ignored.

While the legacy app settings class is used, the dictionary settings can still be accessed via the prefixed setting (for example, settings.MYAPP_FRUIT).

Change Log

2.0.1 (10 August 2019)

  • Add Python 3.7 and Django 2.2 to the test matrix.

2.0 (24 April 2018)

  • Full rework of project! Import is now from easysettings.app import AppSettings (but left importable from easysettings for better backwards compatibility).
  • Removed isolated settings functionality, unnecessary with a separate settings module for tests and/or use of the TestCase.settings() context manager.
  • Added easysettings.legacy.LegacyAppSettings for providing backwards compatibility for prefixed project settings when moving settings to a dictionary rather than individual settings with the same prefix.

1.1 (4 April 2017)

  • Django 1.11 compatibility.

1.0.1 (24 May 2012)

  • Included extra source files.

1.0 (16 April 2012)

  • Initial release.
