Need help about inheritance mapping polymorphic relationships

[bocanhcam]

I have 3 tables like the above.
I want to make the relationship between column Article with Customer and Member using creator_id and creator_type.
I'm struggling with how to create relationships for these table entities.
I already use @ORM\DiscriminatorColumn(name="discriminator_type", type="string", length=255) to define the type of each entity so I don't think of another way how to do it.
Can anyone give me a sample code?
Thanks a lot!!!
By the way, I use Symfony 5

I see what you’re trying to do, but relational databases don’t work that way. You cannot have the creator_id reference either a member or a customer with a foreign key, depending on the creator_type value.

(Yes, you can do this without foreign keys, but again, that’s not how relational DBs are designed to work, and it won’t work with the ORM that way.)
