django-object-cloner

Easy way to clone/duplicate the objects including their child's with recursively.

For real case in e-commerce system like amazon, e-bay, etc. When you become a seller and you have the products to sale, one of the feature in seller admin such is "duplicate product/copy product/clone product" to make the seller easy clone/duplicate the similar product without uploading again.

Strategy

1. def clone_object(obj, attrs={}) starts by build a "flat" clone of the given "obj"
2. M2M fields are managed by replicating all related records found on parent "obj" into "clone"
3. for 1-1 and 1-N relations, we clone all child objects by calling recursively clone_object(), but overridding the remote field with the new cloned object

>>> from object_cloner.utils import clone_object
>>> from app.models import Product
>>>
>>> product = Product.objects.first()
>>> product.pk
1
>>>
>>> cloned_product = clone_object(product)
>>> cloned_product.pk
2
>>>
