使用peewee访问远程MySQL数据库 [英] Accessing remote MySQL database with peewee

问题描述

我正在尝试使用peewee连接到Amazon RDS上的MySQL数据库，但无法使其正常工作.我是数据库新手，所以我可能在做一些愚蠢的事情，但这就是我正在尝试的事情:

I'm trying to connect to a MySQL database on Amazon's RDS using peewee and I can't get it to work. I'm new to databases so I'm probably doing something stupid, but this is what I'm trying:

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)

我想念什么?为什么说我只给它一个参数，而我给它五个呢?

What am I missing? Why is it saying I'm only giving it one argument when I'm giving it five?

非常感谢Alex

推荐答案

我将其更改为这样，并且可以正常工作:

I changed it to be like this and it worked:

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()
