Relationship of different objects to a similar table or two different Yii2 tables?

Question

MySQL

Hello. To have conditionally two different objects of the book and films in different tables. Each of these objects has a one-to-many relationship i.e. a movie can have a lot of links, and books can similarly, how to optimally implement the architecture so as not to duplicate the "links" table, where each one will refer to films in the first case and books in the second?
