how Django processes models # Meta options 4.2 | Python is Django
In Django, a meta class is a class that defines metadata options for a model. These options are used to control various aspects of a model's behavior.
# ten common meta class options in Django models:
1.db_table: This option allows you to specify the name of the database table that the model will use.
2.ordering: This option lets you specify the default ordering for the model. For example, you can sort by a particular field or multiple fields.
3.verbose_name and verbose_name_plural: These options allow you to specify the human-readable name of the model, both in the singular and plural form.
4.unique_together: This option allows you to specify a set of fields that must be unique together.
5.permissions: This option allows you to specify the permissions that can be granted to users for this model.
6.abstract: This option allows you to create an abstract base class for a model that is not intended to be instantiated directly.
7.default_related_name: This option allows you to specify the default name for the reverse relation from the related model back to this model.
8.get_latest_by: This option allows you to specify the default field to use when getting the latest object for this model.
9.indexes: This option allows you to specify the database indexes to be created for the model.
10.app_label: This option allows you to specify the name of the app to which the model belongs. This is useful when you have models in multiple apps with the same name.
