Currently I am working to convert my python2 Django web-project into python 3.
My project contains lots of models.py files so I have to add manually on_delete=models.CASCADE in all files where I have set default it in python 2.
Now there are around more than 2000 instances where I need to do same practice.
Is there are any hacks or possible solution available so that I can set on_delete=models.CASCADE in my all models instantly.
