文档中的Mongoengine creation_time属性

您可以覆盖save方法。

class MyModel(mongoengine.document):    creation_date = mongo.DateTimeField()    modified_date = mongo.DateTimeField(default=datetime.datetime.now)    def save(self, *args, **kwargs):        if not self.creation_date: self.creation_date = datetime.datetime.now()        self.modified_date = datetime.datetime.now()        return super(MyModel, self).save(*args, **kwargs)
