Allows models to be ordered and provides a simple admin interface for reordering them.

Based on http://www.djangosnippets.org/snippets/998/ and http://www.djangosnippets.org/snippets/259/

Requires:

• Django 1.4

$ python setup.py install

Add ordered_model to your SETTINGS.INSTALLED_APPS.

To add ordering to your model, inherit from the OrderedModel class:

from django.db import models
from ordered_model.models import OrderedModel

class Item(OrderedModel):
    name = models.CharField(max_length=100)

Model instances now have move_up() and move_down() methods to move them relative to each other.

To add re-ordering controls to a model's admin interface, inherit from the OrderedModelAdmin class. Your model admin will now have a method called move_up_down_links, which outputs html for two buttons which control model ordering. Use the admin class's list_display property to add these buttons into the admin interface:

from django.contrib import admin
from ordered_model.admin import OrderedModelAdmin
from .models import Item


class ItemAdmin(OrderedModelAdmin):
    list_display = ('name', 'move_up_down_links')

admin.site.register(Item, ItemAdmin)
