Web2py:将参数传递给 db Connection()

问题描述

在 web2py 中，在 gluon/contrib/pymysql/connections.py 中有一个函数可以创建一个新的 mySQL 连接:

In web2py, in gluon/contrib/pymysql/connections.py there is a function that creates a new mySQL connection:

def __init__(self, host="localhost", user=None, passwd="",
             db=None, port=3306, unix_socket=None,

有没有办法从 web2py 向这个函数传递参数?

Is there any way to pass parameters to this function from web2py?

推荐答案

如这部分的文档，你可以在实例化时指定driver_args的字典<代码>DAL:

As noted at the very end of this section of the documentation, you can specify a dictionary of driver_args when instantiating DAL:

db = DAL(<connection_string>,
         driver_args=dict(host='localhost', port=3306, ...))
