Q object relationship spanning

[yopi]

the route 835 is a record of the table payment itself and does not appear when searched in the table deal via the FK deal

>>> MtPayment.objects.filter(route=835)
[<MtPayment: 132>]
>>> MtPayment.objects.filter(deal__route=835)
[]

But filtering on both criterias using a Q object fails to find anything:

>>> MtPayment.objects.filter(Q(route =835)|Q(deal__route=835))
[]
