in fastapi_users we do:

current_active_user = fastapi_users.current_user(active=True, verified=True)

and then have a dependency to make sure a user who is logged in is accessing the endpoint.
But is there any way to reverse it?

for example, we have this, that checks if user exists:

@router_orders.post("/cart/items/", response_model=CartItemResponse | MessageResponse)
async def add_cart_item(
item: CartItemCreateRequest,
test: bool = Query(False, description="If true, return example data."),
db: AsyncSession = Depends(get_db),
user: User = Depends(current_active_user),
):

but can we do something like:

@router_orders.post("/cart/items/", response_model=CartItemResponse | MessageResponse)
async def add_cart_item(
item: CartItemCreateRequest,
test: bool = Query(False, description="If true, return example data."),
db: AsyncSession = Depends(get_db),
unauthorized_user =NOT Depends(current_active_user),
):

?

Basically what I am trying to do is make sure users do not access the log in / register page once they are logged in.
