Django Admin Related

this project makes it impossible for the user to delete objects that contain other objects related by django admin.

Obs: this project works only in django admin

pip install django-admin-related

Usage:

1. Add to your INSTALLED_APPS, in settings.py:

   INSTALLED_APPS = [  
       ...
       'django_admin_related',
       ...
   ]  
   

2. Create admin for your model:

   from django.contrib.admin import register
   from django_admin_related.admin import VerifyRelated
   
   @register(YouModel)
   class YouModelAdmin(VerifyRelated):
       """
           from best performance use `verify_related_fields`
           because this check all fields is a point to other model
           and `verify_related_fields` is a direct way.
       """
       pass

   class YouModelAdmin(VerifyRelated):
       """
