Question

我对Python和Django都比较陌生，而且我有一个由别人开发的应用程序。我正在尝试编写一个自动打开SSH隧道的脚本，并从我的本地机器运行命令到我的远程postgres数据库，以便我可以在本地进行解析 - 这通常是通过键入{{1 }}。这在我run a manual SSH tunnel之前有效，但现在想要将其设置为在脚本中运行并自动关闭连接。我的脚本目前设置如下：

python manage.py parse

当我运行脚本（位于我的应用的根文件中）时，我现在收到以下错误：

import psycopg2
import sshtunnel
from django.core.management import execute_from_command_line

sshtunnel.SSH_TIMEOUT = 5.0
sshtunnel.TUNNEL_TIMEOUT = 5.0

with sshtunnel.SSHTunnelForwarder(
    ('ssh.pythonanywhere.com'),
    ssh_username='ssh_username', ssh_password='ssh_password',
    remote_bind_address=('username2.postgres.pythonanywhere-services.com', port)
) as tunnel:
    params = {
        "dbname": 'dbname',
        "user": 'user',
        "password": 'password',
        "host": 'host',
        "port": tunnel.local_bind_port,
    }

    connection = psycopg2.connect(**params)
    cursor = connection.cursor()

    execute_from_command_line(["manage.py", "parse"])

    cursor.close
    connection.close()

在我看来，这肯定是一个我没有改变某个地方脚本名称的问题，但是通过我的系统进行了搜索，我似乎无法找到＆＃39; yoursite＆＃39;在我的任何代码中。有没有人知道这个错误所指的代码在哪里？
