使用peewee訪問遠程MySQL數據庫

Question

我試圖使用peewee連接到亞馬遜的RDS上的MySQL數據庫，我無法讓它工作。我是新來的數據庫，所以我可能做一些愚蠢的，但是這是我嘗試：

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() 

它在第二行掛斷了電話，說__init__() takes at least 2 arguments (1 given)

我缺少什麼？爲什麼它說我只給了它一個參數，當我給它五個？

非常感謝，亞歷克斯

我改變了它是這樣的，它的工作：

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() 

謝謝你們， 亞歷
