python - Django Python ...更新数据库中的多个元素

Question

迎角， 我知道这个问题很愚蠢，但我被困在这里

这是代码...

nq = Notifications.objects.filter(userid__iexact=q)
    for string in nq:
            string.markType = "Read"
    results = Notifications.objects.filter(Q(userid__iexact=q)).order_by('-id')

但是 markType 未能设置为“Read”...为什么？

Answer 1

您可能打算在更改后保存对象:

nq = Notifications.objects.filter(userid__iexact=q)
for string in nq:
    string.markType = "Read"
    string.save()
results = Notifications.objects.filter(Q(userid__iexact=q)).order_by('-id')
