Def update_priorities(model, start, end, select=lambda x, y: x.objects, selection_arg=None, minus=False):

Question

Def update_priorities(model, start, end, select=lambda x, y: x.objects, selection_arg=None, minus=False):

print(f"start {start}")
print(f"end {end}")
print(f"minus {minus}")
if end:
seq = select(model, selection_arg).filter(priority__gte=start).exclude(priority__gte=end+1).order_by('-priority')
else:
seq = select(model, selection_arg).filter(priority__gte=start).order_by('-priority')
print(f"seq {str(seq)}")
for entity in seq:
if minus:
entity.priority -= 1
model.save(entity)
else:
entity.priority += 1
model.save(entity)
я могу делать select(model, selection_arg) при дефолтном селекте и селект_аргументе?
