I have Student model (which includes studentId field - ID for student, not to be mistaken with student_id) and Course model. I wrote another model StudentCourse to demonstrate the relationship between aforementioned models in which it contains Many2one fields: student_id and course_id respectively. I retrieve studentId by using related field through student_id. After that, in Course model, I input another field student_course_ids (One2many) which references toward student_id. The data retrieved is correctly. However, when i tried to edit student's information in the one2many field (student_course_ids) in Course Form View, I received the following KeyError:

I tried to edit the StudentCourse model separately in its own form view and its went through without a hiccup. But the error only occurs at the One2many view in Course model's Form View. Please help me with this. I have been look up for this matter over 3 days and no luck for me. Thanks.

Can you post your Code pls?
