解决mongoengine报错mongoengine.errors.FieldDoesNotExist: The fields xxx

错误代码:

mongoengine.errors.FieldDoesNotExist: The fields "{'saled_fee', 'start', 'saled_count', 'ctime', 'progress', 'saled', 'url', 'utime', 'end'}" do not exist on the document "ArtiInfo"

解决办法:

若要在加载数据时有额外字段时忽略此错误，请在你的元词典里设置strict到False。

from mongoengine import *
from mongoengine import connect
connect('MI', host='127.0.0.1', port=27017)# ORMclass ArtiInfo(Document):summary = StringField()name = StringField()price = FloatField()status = StringField()meta = {'collection':'zc_items', 'strict': False}
