Many-To-One with multiple target entities

Question

This seems simple but I can\'t get it right:

There are three entities: Fruit, Vegetable and Snack. Snack has the fields

Answer 1

You can create a (abstract) mapped superclass called Food, which can hold some basic information for Fruit and Vegetable.

The keyword for your question is inheritance mapping, this is the documentation for it: https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/inheritance-mapping.html#inheritance-mapping

Then you could reference this mapped superclass in your entity relationship.
