How to delete a polymorphic row when deleting a model?

[lucassimines]

Hello guys, I have a Category model that has a polymorphic table called "categorizables"

I have model called Product that has association with the Category model. But when I delete a product, the categorizable table still keeps the record of product_id category_id how can I delete this relation row when deleting a product?

If I'm not mistaken, a polymorphic row is a row that can reference different tables?
If that's the case, that is not supported, as we rely on ON DELETE CASCADE to delete the row from the through table, and such a row would not have a foreign key.

You need to delete it manually
