When I have an existing db with 2 tables person - phones. In relation 1:n (a phone can have only 1 user in this example). In this db the conection is with primary keys, comun. So far so good.
Now, if I try with Valentina and the idea from Recid and Link. How can I do this? Write the primary key to the RecId I think is not the concept.... But how know the Valkentina db what are the phones from a person? I have not found in the helps.
