This app aims at easing implementing drag & drop reordering of inline data in Django Admin.
Recent version of Grappelli includes drag and drop inlines, so if you are already using Grappelli, installing django-inline-ordering does not make sense. If you didn't evaluate Grappelli yet, I encourage you to do so!
The django-inline-ordering is being tested during development on:
- Fx 3.5+
- Google Chrome 10+
- Opera 11+
Suggestions on how to improve django-inline-ordering are very welcome.
- Put 'inline_ordering' on your python path
- Add 'inline_ordering' to INSTALLED_APPS tuple in settings file
For each model that you want to be reorderable with drag & drop, you need to
setup an admin class and slightly modify model declaration. This way you can
easily apply reordering to existing model classes. You'll also have to run
collectstatic task or copy one file to your MEDIA_ROOT when using Django
Let's start with a simple example: Gallery has many Images. User might want to reorder the photos in the gallery to fit his likings.
Setup your admin inline class to inherit after OrderableStackedInline
from inline_ordering.admin import OrderableStackedInline class ImageInline(OrderableStackedInline): model = Image
class GalleryAdmin(ModelAdmin): model = Gallery inlines = (ImageInline, ) class Media: js = ( 'http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js', )
Altough this could be done automatically, some widgets like for example the WYMEditor widget, use their own way of loading jQuery UI, which could lead to conflicts with inline-ordering.
Setup your model to inherit after Orderable
from inline_ordering.models import Orderable class Image(Orderable): src = models.ImageField(upload_to='gallery/images') title = models.CharField(max_length=255) alt = models.TextField() class Meta(Orderable.Meta): pass
As ordering column was named
inline_ordering_position, avoid using this name in your model.
The Meta class declaration is NOT necessary - add it only if you need to set your own meta attributes.

Since Django 1.3, there is a staticfiles app that django-inline-ordering is aware of. Just run
manage.py collectstaticto copy/symlink media files.
The simplest way, back in Django 1.2, was to copy
If you however believe that would make a mess, take advantage of the 'INLINE_ORDERING_JS' setting and set it to a location which should be requested when accessing orderable inlines:
INLINE_ORDERING_JS = STATIC_URL + '/js/third_party/inline_ordering.js'
- Reordering won't work for new records until saved. This needs a onchange handler for the record form or some model refactoring.
- At this point there is no support for tabular inlines. If you would like to approach this problem, fork the project on Github.
A simple test project has been added in fdc2189 under tests/testproject. Use tools/buildenv to build a virtualenv for development and syncdb to create necessary models and admin permissions. No unit tests at this point as this is a browser-side thing mostly, improvements welcome.
