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

.. code-block:: python

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

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