scaffold and services in the model

[Sascha Broich]

Hello,

when I use scaffold for an entity I'm not able to use the entity's repository in a service written in the model.
There is always a workflow error "Couldn't resolve reference to EntityRepository" during validation.
So the scaffold parameter is useless because I have to create the repository and its methods in my model anyway.

Is there a way to use the scaffold parameter and create a service in the model?

That is true. Scaffold is mostly for prototyping or simple scenarios.

If you need to inject the repository you need to define an empty repository.

    Service SomeService {
    inject @MyEntityRepository
   
    @MyEntity doSomething;
    }
   
    Entity MyEntity {
    scaffold
    String name
   
    Repository MyEntityRepository {
    }
    }

When delegating from service to repository you need to define at least the operation you are delegating to.

    Service SomeService {
    saveMyEntity => @MyEntityRepository.save;
    }
   
    Entity MyEntity {
    scaffold
    String name
   
    Repository MyEntityRepository {
    save;
    }
    }

And you can use scaffold but add your own additional operations.

    Service MyEntityService {
    doSomethingElse => @MyEntityRepository.somethingElse;
    }
   
    Entity MyEntity {
    scaffold
    String name
   
    Repository MyEntityRepository {
    @MyEntity somethingElse(String foo);
    }
    }


I'm not sure if this helps. Please explain your scenario more if you need further clarification.

This could be said more explicit in the documentation.

That is, what renders scaffold useless when it comes to a not-every-entity-has-its-own-service situation.
