Mongoengine is inspired by Django's ORM, and like Django, it uses order_byto sort the result set. order_bytakes a variable number of string arguments, which are the field names (as defined in your documents) optionally preceded by a "-" (to indicate a descending sort, i.e. highest first).
Mongoengine 的灵感来自 Django 的 ORM，和 Django 一样，它用于order_by对结果集进行排序。order_by采用可变数量的字符串参数，这些参数是字段名称（如您的文档中所定义），可选地以“ -”开头（表示降序排序，即最高的在前）。
For example:
例如：
class Person(Document):
first_name = StringField()
last_name = StringField()
age = IntField()
# later
people = Person.objects.order_by('last_name', '-age')
