exclude feelds with find_one ?

[dandaniel5]

I want to use find_one({ query }, { _id: 0, etc: 0 or 1 }).

Example of my object in DB:
class UserPublic(BaseModel):
tg_id: int
username: Optional[str] = None

I only need tg_id. I feel like it should be possible to use the native find_one(..., { "username": 0 }).

Tied like this:

user = await User.find_one(User.tg_id == int(tg_id), projection_model=UserPublic)
    if not user:
        return ...
    
     user.intro_completed = True
     await user.save()

But it’s obviously wrong 🙂
