App Settings for Django 1.7

Django Pods is a minimalist package that lets you configure default settings for your reusable apps, and allows developers using your apps to override these defaults in their own project settings.

This package is largely inspired by Django Rest Framework and Django AllAuth and adapted to work with Django 1.7 Applications, but also with any classes extending pods.apps.AppSettings.

Preview

Django Pods allows developers to customise app settings in two ways:

1. Dictionary style (as per Django Rest Framework):

   YOUR_APP = {
       "SETTING": "VALUE"
   }

2. Prefix style:

   YOUR_APP_SETTING = "VALUE"

Installation

pip install django-pods

Usage in Reusable Apps

1. Add django-pods to the install_requires of your setup.py:

   setup(
       name="rock_n_roll",
       install_requires=["django-pods", ...],
       ...
   )

2. Add the AppSettings mixin to your AppConfig implementation in rock_n_roll/apps.py:

   from django.apps import AppConfig
   from pods.apps import AppSettings
   
   
   class RockNRollConfig(AppSettings, AppConfig):
       name = 'rock_n_roll'
       verbose_name = "Rock ’n’ roll"
   
       # Path to app settings module
       settings_module = "rock_n_roll.app_settings"
   
       # Optional
       settings_imports = ("CLASS_TO_IMPORT",)
   
       # Optional
       # defaults to the capitalized class name, e.g. ROCK_N_ROLL_CONFIG
       settings_key = "ROCK_N_ROLL"

3. Declare your default app settings in rock_n_roll/app_settings.py:

   QUESTION = "What is your favourite band?"
   ANSWER = "The Rolling Stones"
   CLASS_TO_IMPORT = "path.to.ClassToImport"

4. Access your settings anywhere in your package:

   from django.apps import apps
   
   app = apps.get_app_config('rock_n_roll')
   
   app.QUESTION
   # What is your favourite band?
   
   app.ANSWER
   # The Beatles
   
   app.CLASS_TO_IMPORT
   # <class 'path.to.ClassToImport'>

Settings can also be accessed directly via the class:

from rock_n_roll.apps import RockNRollConfig


RockNRollConfig.QUESTION
RockNRollConfig.ANSWER
RockNRollConfig.CLASS_TO_IMPORT

Note

AppSettings ``settings`` Property

AppSettings implements __getattr__ to proxy to the settings attributes of the class:

app.QUESTION == app.settings.QUESTION

# or

RockNRollConfig.QUESTION == RockNRollConfig.settings.QUESTION

Note

Usage with Django < 1.7

Prior to Django 1.7, there wasn’t a logical place to create a class representing an app. However, any class can extend AppSettings. For example, in models.py:

from pods.apps import AppSettings


class AnyClass(AppSettings):
    settings_module = "rock_n_roll.app_settings"

Import your app class directly:

from .models import AnyClass

AnyClass.QUESTION

Usage in Projects

1. Install the app that uses Django Pods:

   pip install rock_n_roll

2. Add the app to the INSTALLED_APPS of your project/settings.py:

   INSTALLED_APPS = (
       ...
       "rock_n_roll",
       ...
   )

3. Override the app’s settings as needed:

   # Dictionary style
   ROCK_N_ROLL = {
       "ANSWER": "The Beatles",
   }
   
   
   # Prefix style
   ROCK_N_ROLL_ANSWER = "The Beatles"
