Session: How to Ignore Entity Changes

To indicate that an entity should be ignored when tracking changes, use the advanced session ignore_changes_for method.

Using load again to retrieve this entity will not initiate a server call.

The entity will still take part in the session, but be ignored when save_changes is called.

Syntax

def ignore_changes_for(self, entity: object) -> None: ...

Example

product = session.load("products/1-A", Product)
session.ignore_changes_for(product)
product.units_in_stock += 1  # this will be ignored for save_changes
session.save_changes()
