PostgreSQL和金字塔：ProgrammingError：关系“记录”不存在

Question

我必须测试现有的金字塔应用程序。

我必须使用包含某些记录的数据库来设置本地PostgreSQL服务器。

然后，我必须设置一个python虚拟环境并为现有的金字塔应用程序启动Web服务器。

该应用程序已在本地主机上启动并运行，但是当我尝试通过网页在connected（！）数据库中添加记录时，出现错误。 我想它没有连接到数据库。

因为我是Pyramid和PostgreSQL的新手，所以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（在另一个终端中）。

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

Answer 1

您尝试查询不存在的SQL表records 。

或

• 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，请修复您的SQL查询以进行拼写并引用正确的表

pgcli -PostgreSQL更好的命令行界面
