如何使用MongoEngine将更多项目添加到EmbeddedDocument？
如何使用MongoEngine将更多项目添加到EmbeddedDocument？
提问于 2012-06-03 23:17:52
我正在尝试检查是否已经存在具有当前日期的项目，如果没有，我将添加它。下面的代码没有提示任何错误，但没有将任何内容保存到MongoDB
if len(site.DaylyLog) != 0:
print len(site.DaylyLog)
print site.DaylyLog[-1]
current_date_daylylog = site.DaylyLog[-1]['aggregate_date']
else:
current_date_daylylog = ''
if current_date_daylylog == datetime.date.today():
#update document
print current_date_daylylog
print "calculating averages"
site.DaylyLog[-1].average_response_time = (site.DaylyLog[-1].average_response_time+record_uptime.response_time)/2
site.DaylyLog[-1].average_uptime = (site.DaylyLog[-1].average_uptime+100)/2
site.save()
else:
print current_date_daylylog
print "adding new uptime"
print site.url
aggregate_uptime = AggregatedUptime()
aggregate_uptime.average_response_time = record_uptime.response_time
aggregate_uptime.average_uptime = 100
aggregate_uptime.total_downtime = 0
aggregate_uptime.aggregate_date = datetime.date.today()
print aggregate_uptime.aggregate_date
print aggregate_uptime.average_response_time
site.DaylyLog.append(aggregate_uptime)
site.save()
print site.DaylyLog[-1].aggregate_date回答 1

正如我在上面的评论中提到的。我发布的代码是好的，但它重新引用了我在模型中所做的更改。这只是一个新手的问题。:-)
旧的模型是
class Checkr(Document):
name = StringField()
slug = SlugField()
url = URLField()
frequency = IntField()
owner = IntField()
start_date = DateTimeField()
end_date = DateTimeField()
current_response_time = FloatField()
current_response_code = IntField()
hourly_log = ListField(EmbeddedDocumentField(AggregatedUptime))
dayly_log = ListField(EmbeddedDocumentField(AggregatedUptime))
weekly_log = ListField(EmbeddedDocumentField(AggregatedUptime))它应该在什么时候
class Checkr(Document):
name = StringField()
slug = SlugField()
url = URLField()
frequency = IntField()
owner = IntField()
start_date = DateTimeField()
end_date = DateTimeField()
current_response_time = FloatField()
current_response_code = IntField()
HourlyLog = ListField(EmbeddedDocumentField(AggregatedUptime))
DaylyLog = ListField(EmbeddedDocumentField(AggregatedUptime))
WeeklyLog = ListField(EmbeddedDocumentField(AggregatedUptime))页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
