Can someone explain what maked in cascade means?

Let's say you have a User model and an Order model where an order is placed by a user. Order.user would be a ForeignKey to User.

This is what will happen for each policy when you try to delete a User with that given policy:

• HARD_DELETE: delete the user permanently and delete all of the orders from that user (cascade down the relations).
• HARD_DELETE_NO_CASCADE: delete the user permanently, but do not touch the orders (do not cascade).
• SOFT_DELETE: soft delete the user, but do not touch the orders (do not cascade).
• SOFT_DELETE_CASCADE: soft delete the user and soft delete all of the orders from that user (cascade down the relations).
• NO_DELETE: don't delete or change anything.

These constants should perhaps be renamed so that they're more in line with each other. But they're probably named like that because of Django defaults. Google what cascading in SQL is for more detailed info on cascading.
