Q: doctrine usage

[basz]

I see this library supports doctrine entities as input to the serialiser.

https://github.com/nilportugues/php-json-api/blob/aa305a4ea7a9aef0be3cf243c1e2cf3c9efb3411/tests/Integrations/Doctrine/DoctrineTest.php

That example works without relationships. It seems I get into an infinite loop when I have two entities referencing each other.

identity has many preferences.

So either I am doing something wrong, perhaps I should not fetch eager or something. Or this is not possible with this library or I might have found a bug...

I have pinned it down to the serialiser::serializeData method in the serializer.

i see this is actually an issue with your serialiser nilportugues/php-serializer#14

[basz]

Perhaps not : The JsonApiSerializer extends DeepCopySerializer which doesn't seem to protect against circular dependencies...

[nilportugues]

Circular dependencies are bad design.

I can code against bad design, but it really introduces lots of complexity to the library to support a bad practice.

[basz]

Hi, I rather do it right then wrong... But I would argue circular dependencies aren't bad design perse. They exist in doctrine entities. Think of a one to many relationship. Although I am never interested in traversing the identity from a Preference. I want the relationship defined in the owning side (preference) becuase of the constained advantage the cascade option gives me. (When ever I remove a user all his preferences are also deleted.)

ps. Simply changing the DeepCopySericalizer to Serializer fixed this...

thoughts? advise? still stuck at serialising entities
