I'd like to be able to check the BaseModel objects returned by a route before they are serialized. what would be the best way to do that? i couldn't find any obvious callbacks where i could get the returned objects passed in before serialization. is this possible with middleware?

i ended up creating a custom APIRouter that overrides add_api_route and wraps the endpoint with a function that copies the endpoint's function signature. still interested if there are other options though :)

Is it not possible to use response_model

Is it not possible to use response_model

so one thing I forgot to mention is that.. I have to check and validate the returned BaseModel's using the current user, ie. I have a Depends(get_user) parameter in the endpoint, that I would like to use. I tried with response_model, and although in fastapi's routing.py class I did see that I could override BaseModel.json() and do some checking there, I couldn't find an easy way to reuse my injected dependency. or is there a way?
