[Auto create entity with values from another one and the current user](https://ecaguide.org/library/simple/auto_create_entity_with_values_from_another_one_and_the_current_user/) This model creates a node automatically when a user creates a new page. It then uses field values from the created page and from the user, and combines them into the title of the new node.
