Django objects.create производит больше выходных данных, чем должно

Question

Существует два списка:

master_values:

[{<Truckdb: Truckdb object (141)>: [<ItemBatch: Iphone>, <ItemBatch: Iphone>, <ItemBatch: Iphone>, <ItemBatch: Iphone>]}, {<Truckdb: Truckdb object (18)>: [<ItemBatch: Iphone>]}]

truck_objects:

[<truck_name: 17 Feet 6000>, <truck_name: Tempo 407 1500>]

Когда я запускаю следующий код, он создает больше диспетчерского плана, чем должен:

for i in range(len(truck_objects)):
    for j in range(len(master_values)):
        if i == j:
            for q, w in master_values[j].items():
                for aa in range(len(w)):

                    print("len(w)  ",len(w))
                    DispatchPlan.objects.create(owner=request.user,
                            truck_type=container_object,
                            truck_name=truck_objects[i],
                            items=w[aa])

В этом он создал 5 планов отправки, когда он должен был создать только два
