我正在尝试使用Django中的Kombu和Celery自定义this tutorial来创建点击计数器。该教程解释了如何为url执行此操作,但我想要做的是创建Click模型,将帖子定义为P-000324
字段,然后每当有人查看该帖子时,我会调用该帖子的增量点击
我有两个问题:
第一个是我应该在视图中放置函数调用,因为我使用的是通用视图(见下文)?
第二个是我应该如何使用ForeignKey
?我是否将对象写入函数?
models.py
message
messaging.py
class ClickManager(models.Manager):
def increment_clicks(self, for_url, increment_by=1):
click, created = self.get_or_create(url=for_url, defaults={"click_count": increment_by})
if not created:
click.click_count += increment_by
click.save()
return click.click_count
class Click(models.Model):
obj = models.ForeignKey(Post)
click_count = models.PositiveIntegerField(_(u"click_count"), default=0)
objects = ClickManager()
def __unicode__(self):
return self.obj
views.py
def send_increment_clicks(obj):
connection = establish_connection()
publisher = Publisher(connection=connection, exchange="clicks", routing_key="increment_click", exchange_type="direct")
publisher.send(obj)
publisher.close()
connection.close()
def process_clicks():
connection = establish_connection()
consumer = Consumer(connection=connection, queue="clicks", exchange="clicks", routing_key="increment_click", exchange_type="direct")
clicks_for_url = {}
message_for_url = {}
for message in consumer.iterqueue():
obj = message.body
clicks_for_url[obj]= clicks_for_url.get(obj, 0) + 1
if obj in messages_for_url:
messages_for_url[obj].append(message)
else:
messages_for_url[obj] = [message]
for obj, click_count in clicks_for_url.items():
Click.objects.increment_click(obj, click_count)
[message.ack() for message in messages_for_url[obj]]
consumer.close()
connection.close()
