I created different associations like here
https://sailsjs.com/documentation/concepts/models-and-orm/associations
but no foreign keys are created

Start with the linked Sails associations documentation and reproduce the report using a concrete association, database adapter, and version set; the issue leaves those details blank. Done means identifying why the association does not create foreign keys and confirming the expected keys are created in the database.
