Django other versions vs Django 3 conflicts :

• from django.conf.urls import url vs from django.urls import path : url and path are not same !

• Django 2.0 removes the django.core.urlresolvers module, which was moved to django.urls in version 1.10. You should change any import to use django.urls instead, like this:

    from django.urls import reverse
  

• In OneToOneField() and Foreignkey() : on_delete=models.CASCADE field is required!

• use from django.contrib.auth.views import LoginView insted of from django.contrib.auth import views and use LoginView.as_view() in the urlpattern insted of 'views.login'

Note : Baler update and you can get error :

• use-pathlib-in-your-django-project
