用tornado写了一个小程序一直报错

[o618]

self.topic_model.update_topic_by_topic_id(topic_id, {"up_vote": template_variables["votes"],})

template_variables["votes"] = self.vote_model.get_vote_by_topic_id_and_trigger_user_id(topic_id, self.current_user["uid"])

想对某个话题进行投票数统计，但运行一直报错："up_vote": template_variables["votes"],
KeyError: 'votes'

弄了一下午都没弄好，怎么破？

把第二句放倒第一句前面…

@whtsky 放到前面又抛出这个错误：

File "/usr/local/lib/python2.7/dist-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler

看看数据库字段名是否叫“up_vote”，其次，
self.topic_model.update_topic_by_topic_id(topic_id, {"up_vote": template_variables["votes"],})

最后一个逗号删除看看。
