Approach

1. Update the adapt_map decorator and get the typing of the information

   def register(func: Callable[..., R]) -> Callable[..., R]:
      @wraps(func)
      def inner(*args: Any, **kwargs: Any) -> Any:
        return_value = func.__annotations__.get("return")
        print(return_value)
        print(type(return_value))
        assert return_value == str
        return func(*args, **kwargs)
      return inner
   
   @register
   def hello(name: str) -> Iterable[Optional[str]]:
     return f"Hello {name}!"
   
   @register
   def hello(name: str) -> str:
     return f"Hello {name}!"
   

   • We need to check if that is Optional, is a List of objects, or is a single object.
   • We need to keep the import of graphql_gateway.schema in the view model.

2. Use a generic mapper for dataclass with validations using the typing. (Example)

Problem

1. Keep the view and view_model synced with the same typing.
   1. If we only have a parse between the model and graphql_view (similar to marshmallow) we don’t need to worry about the middle object.
2. Sync enum between strawberry and another type.
