Implemented a model for soft deletion (logical deletion) Soft deletion:

The deleted data in the application layer is not deleted in the database but is shielded from the application layer

Inheriting the SoftDeleteModel model will result in the following features:

• Automatically add a field delete_time [field name configurable]
• Data will be marked as deleted and will not be removed from the database on delete
• Automatically add deleted filter rule to the current QuerySet(include relation QuerySet) [optional]
• Tables with foreign key relationships will also undergo soft deletion during cascading deletion [optional]
• Fields with unique constraints will be adjusted to joint unique constraints with 'delete_time' [optional]
