 HOW TO CHANGE THE TIMEZONE ?? --> use local time from python library
-
-WHAT IS META IN MODEL CLASS ??
-WHAT IS from django.contrib.auth import get_user_model ??
 WHAT IS THE DIFFERENCE BETWEEN VIEW AND GENERIC VIEW?? --> There are different classes, Generic has more packages
+WHAT IS META IN MODEL CLASS ?? --> Just Syndax......
+WHAT IS from django.contrib.auth import get_user_model ?? --> You import Django's User Table (<auth_user> in postgres)
