QUESTION
Using Django 1.9 and Python 3.4 I want to copy an existing model instance and all its related data. Below is an example of how I have currently achieved this. My question is, is there a better way?
I have read over posts e.g. Duplicating model instances and their related objects in Django / Algorithm for recusrively duplicating an object this one but, they are over 8 years old and no longer work with Django 1.9+.
Below is how I try to achieve this already, ok or a better way in Django 1.9?
