Django model Meta class options

The Meta class is a way to define metadata for a model class. It allows you to specify various options that control the behavior of the model, such as the database table name, ordering of query results, unique constraints, and more. Here are some commonly used options:

1. db_table: This option allows you to specify the name of the database table that the model should use.
2. ordering: This option allows you to specify the default ordering for query results. You can either provide a list of field names or use the - prefix to indicate descending order.
3. unique_together: This option allows you to specify fields that should be unique together. You can provide a list of field names to create a unique constraint across multiple fields.
4. verbose_name and verbose_name_plural: These options allow you to specify human-readable names for the model. verbose_name is used for singular objects, while verbose_name_plural is used for collections of objects.
5. indexes: This option allows you to specify indexes to be created for the model. You can provide a list of field names or use the models.Index class to specify the index type and any additional options.
6. default_related_name: This option allows you to specify the default name to use for the reverse relation from a related model.
7. constraints: This option allows you to specify constraints to be created for the model. You can provide a list of models.CheckConstraint or models.UniqueConstraint objects to create custom constraints.

These are just a few of the options available in the Meta class. For a full list, you can refer to the Django documentation on model meta options.
