Question

我必须测试现有的金字塔应用程序。

我必须设置一个带有一些记录的数据库的本地PostgreSQL服务器。

然后我必须建立一个python虚拟环境并启动现有金字塔应用程序的web服务器。

应用程序已启动并在localhost中运行但是当我尝试通过网页在连接的（！）数据库中添加记录时，我收到错误。我想它没有连接到db。

因为我是Pyramid和PostgreSQL的新手，我可以遵循任何教程吗？

我遵循的步骤是：

设置本地PostgreSQL服务器。

设置python虚拟环境并启动金字塔应用程序的Web服务器（在不同的终端中）。

错误： pserve development.ini 在PID 13630中启动服务器。在http://0.0.0.0:8080上投放

Answer 1

您尝试查询不存在的SQL表records。

无论

使用PostgreSQL客户端（命令行客户端）在数据库中创建此表
如果您认为该表应该已经存在，那么修复您的SQL查询以进行拼写并参考正确的表

pgcli - 更好的PostgreSQL命令行界面
