- Sequelize 与给定的sequelizerc/config.js 文件连接
- Sequelize 运行迁移文件并使用定义的模型创建表
- Sequelize 运行种子文件但在尝试查询创建的数据时出错,即错误:关系“guest”不存在
我注意到的有趣的事情:在查询 User 表时,我注意到它没有返回我期望的数据......而不是 User 表上的用户,它似乎返回我在其上设置的实际 postgres 数据库用户。
播种机文件
var userId1 = uuidv4();
await queryInterface.bulkInsert(
{ tableName: 'User', schema: 'public' },
[
{email: "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="92e7e1f7e0a3d2f7fff3fbfebcf1fdff" rel="noreferrer noopener nofollow">[email protected]</a>", id:userId1, password: User.prototype.generateHash("password"), createdAt:dateUtil.createDateAsUTC(new Date()), updatedAt:dateUtil.createDateAsUTC(new Date())}
], {}
);
const user = await queryInterface.sequelize.query(
`SELECT * from USER;`
);
console.log(user);
var guestId1 = uuidv4();
await queryInterface.bulkInsert(
{ tableName: 'Guest', schema: 'public' },
[
{id:guestId1, userId: userId1, createdAt:dateUtil.createDateAsUTC(new Date()), updatedAt:dateUtil.createDateAsUTC(new Date())}
], {}
);
const guest = await queryInterface.sequelize.query(
`SELECT * from Guest;`
);
从周围挖掘看来,它可能没有使用正确的数据库模式?我在 postgres 的 public
下有一个,所有表都已正确创建,并且种子数据已正确添加到数据库中。我尝试将架构添加到 config.js 和模型文件中,但没有任何效果。
CONFIG.JS
development: {
username: process.env.DATABASE_USERNAME,
password: process.env.DATABASE_PASSWORD,
database: process.env.DATABASE_NAME,
host: process.env.DATABASE_HOST,
url: process.env.DATABASE_URL,
dialect: 'postgres',
define: {
schema: "public"
}
}
Guest.js
module.exports = (sequelize, DataTypes) => {
var Guest = sequelize.define('Guest', {},
{
tableName:"Guest",
});
Guest.associate = function(models) {
Guest.belongsTo(models.User, {as: 'User', foreignKey: 'userId'}); // Adds userId
};
return Guest;
};
注销时queryInterface模型似乎是空的......
QueryInterface {
sequelize:
Sequelize {
options:
{ dialect: 'postgres',
dialectModulePath: null,
host: 'localhost',
protocol: 'postgres',
define: {},

最佳答案
更正了表名周围双引号的问题:
const guest =等待queryInterface.sequelize.query(
从“客人”中选择*;
);
关于node.js - Sequelize : relation "<tablename>" does not exist when querying table while seeding,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/51660939/
