我正在尝试使用peewee连接到亚马逊RDS上的MySQL数据库,我无法让它工作。我是数据库的新手,所以我可能做了一些愚蠢的事情,但这就是我正在尝试的事情:
import peewee as pw
myDB = pw.MySQLDatabase(host="mydb.crhauek3cxfw.us-west-2.rds.amazonaws.com",port=3306,user="user",passwd="password",db="mydb")
class MySQLModel(Model):
"""A base model that will use our MySQL database"""
class Meta:
database = myDB
class User(MySQLModel):
username = CharField()
myDB.connect()
它挂在第二行,说__init__() takes at least 2 arguments (1 given)
我错过了什么?为什么说我只给它一个参数当我给它五个?
非常感谢,Alex

我改变它是这样的,它起作用了:
import peewee as pw
myDB = pw.MySQLDatabase("mydb", host="mydb.crhauek3cxfw.us-west-2.rds.amazonaws.com", port=3306, user="user", passwd="password")
class MySQLModel(pw.Model):
"""A base model that will use our MySQL database"""
class Meta:
database = myDB
class User(MySQLModel):
username = pw.CharField()
# etc, etc
# when you're ready to start querying, remember to connect
myDB.connect()
谢谢你们, 亚历
