How to access request in Pydantic model

[Ibrahim-abdelaziz]

Hello all,
I'd like to ask you about somepoints as below:-

1- how to access to request in pydantic model in fastapi like serializer in django by (context.get('request'))

2- how to return extra attribute to response model in endpoint like this
@case_router.get("/case", response_model=CaseOut)
async def get_case(db: Session = Depends(get_db), pagination: Pagination = Depends(), auth: HeaderAuth = Depends()):

is_favourite = false
qs = query(Favourite).filter_by(practitioner_id=auth.id).first()
if qs:
is_favourite = true # how to return this attribute with response_model

query = crud.case.get_multi(db_session=db, is_deleted=False)
return pagination.paginate(query)

Could you please help me to know that, thanks.

In future please try to format the markdown in your questions to make them easier to read.

By default there's no way to do this, see #1549.

For now you could use contextvar.

But in general you should avoid referencing the request within validators, since your models should be de-coupled from the request.
