Question

I am developing a course registration site in Django, and I want to allow for lazy deletion of objects; when an object is deleted, it is merely marked as deleted, but not really taken out of the database.

I am adding a new boolean property in user profiles called “deleted.” Subsequently, I want to override a Model’s get/all/filter function(s) to exclude deleted objects when retrieving sets of data.

How do I override the default get function(s)? Thank you.

Override get_query_set for your model manager

https://docs.djangoproject.com/en/dev/topics/db/managers/#modifying-initial-manager-querysets

class MyManager(models.Manager):
    def get_query_set(self):
        return super(MyManager, self).get_query_set().exclude(deleted=True)
