Review Model relationship with multiple tables?

Hi everybody, My app has many models, particularly any logged in user can give feedback and create a review, they can create a plain Review, a DiscountReview and PostReview, this three models are my review models. One DiscountReview belongs to a Discount, one Discount can have many DiscountReviews ... so after some time I just noticed that since a review will always have the same attributes (title, body, rating ... ) maybe I should write a single Review Model and attach it to other Models, a Post, a Discount and other Models can have a Review associated to them or not.

So my question is how can I set up a relationship like this with laravel?

Hi @gabotronix

It sounds like you might be after a polymorphic relationship, see more about it here in the docs: https://laravel.com/docs/master/eloquent-relationships#polymorphic-relationships

Or checkout the video on Laracasts about the subject: https://laracasts.com/series/eloquent-relationships/episodes/5

While the name sounds intimidating, it's really not that bad, especially when you have a something to actually apply it to and it's not all abstract.
