Hi, i’ve a question. We’re looking for handling persistence actions in repository and entitymanager and i see that in spryker core it’s working with the transfer-objects and not with entitytransfer-objects. Is there any reason for that? And if that’s correct to work with transfers and not with entitytransfers in repository and entitymanager, what’s the reason to have entitytransfer objects?

    entitytransfers should not leave the persistence layer

    they leak persistence specific content otherwise

    i think @UK9N7MP96 can shed more light on the reason why they exist in the first place, right?

    Shortly:
    Non Persistence layer - Transfer objects
    Persistence Layer:
    input: Transfer objects
    internally Transfer + EntityTransfer (preferably no Propel objects)
    output: Transfer objects

    In case if performance requirements (like import) you're free to use Propel objects directly, but keep those as more localized as possible.

    i would still like to get a refresher about the entitytransfers’ raison d’être 🙂

    We would recommend to operate with transfer and propel entity in Repository and EntityManager. And do not recommend use propel entities outside those models.

    Ok, that helps a lot i think, thank you. I thought that the EntityTransfer objects exist to communicate with the persistence layer and not only for internal communication in the layer.

    you will, however, see entity transfers being used to set up fixture data in somoe of the tests
