mysql - Is necessary to create an explicit relation in the data base after defining it in the Sails js' model? -


i created model respective relation using following approach

http://sailsjs.com/documentation/concepts/models-and-orm/associations

and seems ok. but, when open model's tables sailsjs created, in mysql workbench. there isn't relation between tables. so; need specify relations or leave tables , continue working relations exists on sailsjs?

join table required n-n relationships, not 1-n ones.

also, in config/models.js, if migrate set 'drop' sails drops , creates tables. when using 'alter' tries create added tables, using 'safe' doesn't create added tables.

there isn't relation between tables

what type of relation expecting?
