Hi Marlysson, thanks for your answer, yes maybe I must be more concise.
In a clasic identifyng relationship, lets say a relation
author-book-page (author has books and books has pages) In this case,
the book primary key includes the author id, and the page primary key
includes the book primary key (author and book ids).
One of the advantages of the identifyng relationship model is that I can
known what book belongs page without need a join, that can be useful
when we have a deep relation tree.
Greetings.

I don't understood your doubt. Are you talking about foreign key?
There are models ( in examples in tutorials ) that use the keyword
reserved "reference" to indicate relationship between tables.

Hi, all web2py tutorials out there works with non-identifying
relationships between tables, is there some caveat or tips for
work with
an identifying relationship data model?
Greetings.
