Why use model Meta class?

The Meta class in Django models allows you to specify additional options or metadata about a particular model. Here are some common use cases for using the Meta class in Django models:

1. Changing the database table name: By default, Django creates a table name by concatenating the app name and the model name. However, you can override this default behavior by specifying the db_table attribute in the Meta class.
2. Setting a default ordering: You can specify the default ordering for objects retrieved using the model’s manager by defining the ordering attribute in the Meta class.
3. Setting unique constraints: You can specify unique constraints for fields in your model by defining the unique_together attribute in the Meta class.
4. Setting verbose names: You can specify verbose names for the model and its fields by defining the verbose_name and verbose_name_plural attributes in the Meta class.
5. Adding custom permissions: You can add custom permissions to your model by defining the permissions attribute in the Meta class.
6. Using a custom manager: You can specify a custom manager for your model by defining the base_manager_name or default_manager_name attribute in the Meta class.

Overall, the Meta class provides a way to customize the behavior of your Django model beyond the default settings.
