请教 Python3 下 pymysql 如何连接 peewee，谢谢

[burnex]

db = pymysql.connect("localhost","testuser","test123","TESTDB" )

class User(Model): 
    username = CharField()

    class Meta:
        database = db

用这种方式报 connection 没有 compiler 这个错

peewee 是个 orm ， pymysql 是个 db driver ，难道不应该是 peewee 通过 pymysql 链接 mysql 吗？ http://docs.peewee-orm.com/en/latest/peewee/database.html

你的用法不对吧： http://docs.peewee-orm.com/en/latest/peewee/database.html#using-mysql

我比较喜欢这种方式： http://docs.peewee-orm.com/en/latest/peewee/database.html#connecting-using-a-database-url
