I have polymorphic relations, like:
company
courses
categories
All has many-to-many relation, so I create a polymorphic relation, many to many.
What I want to do:
If by category add new course or delete, sync with company and remove or add a same course.
If I add a new company to a category, a company gets all the courses too.
My last attempt is to trigger js ajax events and then execute my own js ajax.
