I still don’t really understand what’s the issue. But have you looked at relation managers and the repeater? Are you talking about pivot fields?

this is the error i get: insert into classroom_student (classroom_id, student_id) values (1, 1) SQLSTATE[HY000]: General error: 1364 Field 'academic_id' doesn't have a default value in this relation classroom_student, academic_id is an additional field

Sorry but I can’t help you if you if you just share an error without even knowing what you do. The error says you are missing a required field.
