peewee.ProgrammingError: (1146, "Table 'test.lagou_position_info' doesn't exist")

项目大概简介就是使用scrapy爬取所有拉勾网上技术类职位的信息，并存储到mysql，然后都说peewee是非常轻量的ORM框架，所以我就拿来试下，然后就踩坑了。

完整的traceback如上，但是看不出来什么，唯一觉得有用的信息就是说”Table ‘test.lagou_position_info’ doesn’t exist”，但是我本身用的就是db.create_tables(lagou_position_info, safe=True)，为的就是自动创建表结构，结果还是来提醒我表没有创建。

回头翻了下官方的实例：

db.create_tables([Person, Pet])

好吧，其实参数是个list，而我直接传入了一个model。。。
改成db.create_tables([lagou_position_info], safe=True)，之后正常了
不过还是想吐槽下这个异常还是自己太粗心了。
