from mongoengine import *
from datetime import datetime

connect('PornHub', host='mongodb://192.168.111.129:27017')

# 定义分类文档
class Categories(Document):
    ' 继承Document类,为普通文档 '
    name = StringField(max_length=30, required=True)
    artnum = IntField(default=0, required=True)
    date = DateTimeField(default=datetime.now(), required=True)

cate = Categories.objects.all()
for c in cate:
   print(c.name)

如何使用mongoengine只查询mongo库的部分字段， 而不是全部字段？(待测试)
