Javascript 如何从Knex种子数据到PSQL种子纬度和经度？

我正在使用传单创建一个基于地图的项目。我在PostgreSQL上建立了一个数据库，并使用Knex进行迁移

我已经创建了一系列种子数据，最后一个Knex种子用于向表中添加映射事件，其中一个列类型是PSQL中的POINT。然而，当我尝试在Knex上添加纬度和经度时，它不允许我推到桌子上。如何将lat/lng发布到表格中

import { Knex } from "knex";

export async function seed(knex: Knex): Promise<void> {
    // Deletes ALL existing entries
    await knex("events").del();

    // Inserts seed entries
    await knex("events").insert([
        { eventlocation: {x: 22.28052, y: 114.15749}, eventname: "party", description: "party at LKF 10pm", date: knex.fn.now(), userid: 1},
    ]);
};

这就是被抛弃的错误：

把它写在纸上以备将来参考

为了解决这个问题，在knex种子文件中，输入

knex.raw（'POINT（x，y）'）

将坐标添加到PostgreSQL中。

您可以共享错误日志吗？@AsadJivani Hi Asad，我现在已经添加了错误日志。尝试将

事件位置：{x:22.28052，y:114.15749}

替换为

事件位置：knowed.raw（'（22.28052，114.15749）'））

在您的insert查询中。@AsadJivani您的语法似乎不起作用，但您让我开始测试其他语法，其中一个似乎起作用：

eventlocation:knex.raw（'POINT（22.28052114.15749）
