In this tutorial we will learn about laravel 8 one to many polymorphic relationship. A one-to-many polymorphic relation is similar to a typical one-to-many relation. the child model can belong to more than one type of model using a single association. One to many polymorphic relationship used when a model belongs to more than one other model on a single association model.
For Example, users of your application can comment on posts and videos. Using polymorphic relationships, you may use a single comments table to contain comments for both posts and videos. using morphMany() and morphTo() you can access data.
In this example we will create posts, comments and videos table. all tables are connected with each other like below screenshot and we are create migration and model all table and retrive data using one to many polymorphic relationship in laravel 6, laravel 7, laravel 8.
