django-appregister 0.1

A Django app that provides the building blocks for an app registry system

Django Appregister is a class registry system to allow you to easily implement a puggable

See http://appregister.readthedocs.org/ for further documentation.

Usage Example

In myapp/registry.py:

from appregister import Register

class QuestionRegister(Register):
    base = 'myapp.models.Question'
    discovermodule = 'questions'

questions = QuestionRegister()

if myapp/models.py:

from django.db import models
from myapp import registry

class Question(models.Model):
    pass

@registry.questions.register
class MultipleChoiceQuestion(Question):
    pass

You can then access all classes that have been registered by your app or by another app that extends it:

from myapp import registry

classes = registry.questions.all()

If you add the following lines to your urls.py, you can autodiscover all question sublclasses that have been added to any of the apps in your INSTALLED_APPS:

from myapp import registry

registry.questions.autodiscover()

This then allows developers to add their own subclasses to questions.py within their apps and have them registered to the system for use, in a similar way to the addition and registration of ModelAdmins in admin.py files for Django’s admin.
