Let's say an Author has_many Books.
Field::HasMany loads each Book record and calls display_resource on each one. If the Book dashboard defines display_resource to call book.author.name, N Author records will be loaded, one for each book.
This can significantly slow down load time.
To fix this, Administrate users can now tell Administrate to preload associated records using Rails' includes option. Example usage:
Field::HasMany.with_options(includes: [:author])
