Grouped policies - multiple models

Hello,

I have an question about policies. In my application, I have teachers and students. Students and teachers are stored in / are using Users table. To define teachers and students, I'm using pivot table "teachers_students" with teacher_id and student_id

I have also some relationship table like "student_docs", "students_notes", etc.

I want to give access to these table for teachers who own this student. So, my questions are:

I need to create policies for each table, students_docs etc? I want to give access to student and all his relations table for teacher but I don't really know how to do it.

I want to something like:

• Teacher wants to edit docs of his student
• Laravel check user_id of edited doc
• Second check in pivot if user_id match to teacher id
