django-modelduplication 0.1.1

A simple Django app to duplicate model instance in admin.

=====
Model Duplication
=====

Django admin have `save_as` feature, but that feature have bug with images field, and sometime you want 100% duplication of a model instance with all other related objects and customization, then `save_as` doesn't fit for that purpose.

Quick start
-----------

1. Add "modelduplication" to your INSTALLED_APPS setting like this: ::

INSTALLED_APPS = [
# ...
'modelduplication',
]


2. Define `pre_duplicate` and `post_duplicate` to your models to customize duplication process: ::

class Book(models.Model):
def pre_duplicate(self, origin):
"""This method use to modify object before `save` on duplication.
:type origin models.Model
:param origin the origin instance
"""
pass

def post_duplicate(self, origin):
"""This method is called after finishing the duplication.
:type origin models.Model
:param origin the origin instance
"""
pass
