PostgreSQL and Pyramid: ProgrammingError: relation "records" does not exist

Question

我必须测试现有的金字塔应用程序。

我必须使用包含一些记录的数据库设置本地 PostgreSQL 服务器。

然后我必须设置一个 python 虚拟环境并为现有金字塔应用程序启动网络服务器。

应用程序已启动并且运行在本地主机中，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。我想它没有连接到数据库。

因为我是 Pyramid 和 PostgreSQL 的新手，有没有我可以遵循的教程？

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：保存 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 SQL table records 不存在。

两者都

使用 PostgreSQL 客户端（命令行客户端）在您的数据库中创建此 table
如果您认为 table 应该已经存在，请修复您的 SQL 拼写查询并参考正确的 tables

pgcli - 更好的 Postgre 命令行界面SQL
