how to delete a model saved file when that model is deleted

Comment

from django.db.models.signals import post_delete
from django.dispatch import receiver

@receiver(post_delete, sender=<model name>)
def <name> (sender, instance, **kwargs):
	if instance.<variable name which we saved the file in it>:
		instance.<variable name which we saved the file in it>.delete(False)

**explanation**:
the post_delete is a signal and the receiver creates a connection between the function
and the signal so when post_delete signal is sent from the specified model the function
will be triggered

It looks like your package.json and package-lock.json is not synced.

Try to run this:

$ npm install --package-lock-only

It will generate package-lock.json that is synced on your package.json
