AbstractService, __init__ not called

[djsliders]

Hello,
In order to avoid declaring an init method inside all services, with often the same things (db, current_user) I use an abstract class that UserService (for example) inherits:

class AbstractService(ABC):

    def __init__(self,):
        self.config = config
        self.session = self.config.get_db()


class UsersService(AbstractService):
   def get_users():
      **self.session.query....**

But this doesn't work, as the self.session is never set. But if I create a init in UsersService and call the super.init(), then it works.

Is there a way to fix that ?

THank you for the help and the great framework.

Hi @djsliders
Thanks for raising this issue. I believe that the problem of this abstraction is due to the implementation of the Injectable decorator. I need to take a second look at this. Maybe you can share the repo you are working on, so i can have a real use case to inspect?

My project is not public sorry. But you can create the default project generated, then add an abstract class on the service, with a init that does self.test = "bla"
Then you will see in your App Service (in debug mode or with a print) that this self.test is never set.

Resolved by the dependency-injection rewrite in #125. @Injectable now preserves the provider class and the container constructs real instances, so a subclass without its own __init__ correctly executes its inherited base-class initializer.

The reported inheritance pattern was reproduced against current main and the inherited state is initialized correctly. Closing as completed.
