exclude does not support nested ForeignKey relationship

[ftamy9]

There is a problem on exclude. you can not use nested ForeignKey. I tested on 4.2.1 and 4.1.
for example if you need to find trips that are not trip__method__title=ShippingChoice.ORGANIZATION
Here is the code:

    working_shipments = Shipment.objects.exclude(
        state__in=[
            ShipmentStateChoices.CANCELLED,
            ShipmentStateChoices.DELIVERED
        ],
        trip__method__title=ShippingChoice.ORGANIZATION
    ).filter(
        updated_at__lt=time_threshold,
    )

So you are forced to use a big list on filter instead to use the exclude. like this:

    working_shipments = Shipment.objects.exclude(
        state__in=[
            ShipmentStateChoices.CANCELLED,
            ShipmentStateChoices.DELIVERED
        ]
    ).filter(
        updated_at__lt=time_threshold,
        trip__method__title__in=(ShippingChoice.ALO,  ShippingChoice.SNAP, ShippingChoice.MIAREH)  
    )

the objects.exclude bug need to fix

It's not clear to me what you're trying to report, however, it appears to be a support question. If you're having trouble understanding how Django works, see TicketClosingReasons/UseSupportChannels for ways to get help.

If you believe there is an issue in Django, then please follow our ​bug reporting guidelines and include a clear, concise description of the problem.

Also I just tested exclude with nested fks and it's working ok.

Hi ftamy9

Please don't reopen the ticket unless more information is provided. You'll need to paste your models (only the necessary bits required for testing) + the query you tried that wasn't working.
