我想创建任务来更新排名。
设置.py
djcelery.setup_loader()
BROKER_URL = "amqp://guest:guest@localhost:5672//"
CELERY_TIMEZONE = 'UTC'
我使用 django 工人python manage.py celery worker --loglevel=info
任务：
@celery.task
def update_ranking(duck_pk, new_position):
duck = Duck.objects.get(pk=duck_pk)
print 'duck.rank_number="%s"' % scope.rank_number
# Not in rank yet
if duck.rank_number is None:
pass
else:
# Positive trend regards to previous rank
if duck.rank_number > new_position:
duck.rank_trend = True
# Negative trend regards to previous rank
elif duck.rank_number < new_position:
duck.rank_trend = False
# No changes, keep previous
else:
pass
print 'Title: %s, Old pos: %s, New pos: %s, Trend: %s' \
% (duck.title, duck.rank_number, new_position, duck.rank_trend)
duck.rank_number = new_position
duck.save()
视图部分：
tasks = []
for new_position, duck in enumerate(Duck.objects.all().order_by('-like_number', 'pk')):
tasks.append(update_ranking.s(duck.pk, new_position + 1))
group = celery.group(tasks)
group.apply_async()
该字段rank_number已完美更新，但rank_trend没有！？这在某些时候可能是微小而明显的错误。但我坐在第 5 个小时，什么也没有。当我在没有芹菜的视图上运行代码时，代码可以正常工作。请帮忙。

在上面日志的第 7 行中有Trend: True. 但是在管理面板和视图中是 False。这很奇怪，但我不认识 Celery。

有时十分之一的尝试确实有效。我一直在尝试 50 次，但不知道为什么？我找不到任何合乎逻辑的解释。我认为设置可能有问题。
编辑 21:51
更新了任务输出。在任务开始时添加rank_number了日志。
编辑 21:56 在绝望中我补充说：
for i in range(10000):
for j in range(10000):
1000 * 1000
在视图上的任务调用之后。现在正在工作。捏我一个人！或者解释一下。
