Laravel Polymorphic Relationship allows a model to belong to more than one other model on a single association. There are three types of Polymorphic relationships in Laravel.
One To One Polymorphic Relationship
A one-to-one polymorphic relation is comparable to a simple one-to-one relation; however, the target model can belong to more than one type of model on a single association. For example, a blog Post and a User may share a polymorphic relation to the Image model.
One To Many Polymorphic Relationship
A one-to-many polymorphic relation is comparable to a simple one-to-many relation; however, the target model can belong to more than one type of model on a single association. For example, imagine users of your app can “comment” on both posts and videos.
Many To Many Polymorphic Relationship
Many-to-many polymorphic relations are somewhat more complicated than morphOne and morphMany relationships. For example, a blog Post and Video model could share a polymorphic relation to the Tag model.
