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

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

.. code-block:: python

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


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
            """ 
            pass

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