Duplicating model instances and their related objects in Django / Algorithm for recusrively duplicating an object

Question

I\'ve models for Books, Chapters and Pages. They are all written by a User:

from django.db import models
         


        

Answer 1

There is an option to create a duplicate/clone/save-as-new in django admin.

1. Create a ModelAdmin class of the model you want to clone in admin.py
2. In the class add an admin action like:

 @admin.register(Book)
 class BookAdmin(models.ModelAdmin):
     save_as = True

and this will create a "Save as New" button in your admin panel to completely clone the model object with all it's related fields.
