I have two tables, Category and Worker (with one to many relations) I could generate Category without issue, but generate Worker throw ¨violates foraign key constraint¨. How i could handle ¨category¨ foreign key in Worker table?

Hello @gegonzalez07

This seems to be a bug, i.e your DDL have CamelCase columns and I guess somewhere we dont honor the camelcase.

If you look at the below debug
