Here is how these objects are going to be used in the application. Notice how this depends on the previous packages (web and storage), but not the other way round:
from storage import DBClient, DeliveryStatusQuery, OrderNotFoundErrorfrom web import NotFound, View, app, register_routeclass DeliveryView(View): async def _get(self, request, delivery_id: int): dsq = DeliveryStatusQuery(int(delivery_id), await DBClient()) try result = await dsq.get() except OrderNotFoundError as e: raise NotFound(str(e)) from e return result.message()register_route(DeliveryView, "/status/<delivery_id:int>")
In the previous section, the domain objects were shown and here the code for the application is displayed. Aren't we missing something? ...
