Dependency injection of crud items

[Stevan Meandzija]

from typing import Any, List

from fastapi import APIRouter, Depends, HTTPException
from sqlalchemy.orm import Session

from app import crud, models, schemas
from app.api import deps

router = APIRouter()



@router.post("/", response_model=schemas.Item)
def create_item(
    *,
    db: Session = Depends(deps.get_db),
    item_in: schemas.ItemCreate,
    current_user: models.User = Depends(deps.get_current_active_user),
) -> Any:
    """
    Create new item.
    """
    item = crud.item.create_with_owner(db=db, obj_in=item_in, owner_id=current_user.id)
    return item

Hi all, why in this and similiar examples crud.item(or user) not injected as dependency?
