django-orderedmodel -- orderable models for Django

django-orderedmodel intends to help you create Django models which can be moved up\down (or left\right) with respect to each other.

How to use

There are a few simple steps to follow to make your models orderable:

1. git clone git://github.com/kirelagin/django-orderedmodel.git.
2. Copy (or, even better, symlink) orderedmodel directory to your Django project.
3. Add 'orderedmodel' to INSTALLED_APPS in your settings.py.
4. Ensure that your project is using django.contrib.staticfiles to serve static content (this is now required for compatibility with Django 1.4+).
5. Derive your Model from orderedmodel.OrderedModel.
6. Derive your ModelAdmin from orderedmodel.OrderedModelAdmin.
7. Add reorder field to yout ModelAdmin's list_display.
8. Enjoy!

Now you can use order_by('order') in your query to get instances of your model in desired order (actually it is not neccessary to call order_by explicitly unless you have changed default ordering in your model's Meta).

Example

Suppose you have a django app called testapp. You need an orderable model TestModel.

models.py:

from django.db import models
from orderedmodel import OrderedModel

class TestModel(OrderedModel):
  name = models.CharField(max_length=30)

admin.py:

from django.contrib import admin
from orderedmodel import OrderedModelAdmin

from testapp.models import TestModel


class TestModelAdmin(OrderedModelAdmin):
  list_display = ['name', 'reorder']

admin.site.register(TestModel, TestModelAdmin)

Yep! Now if you create several instances of your model and look into admin site you'll see something like this:

Django versions
