Sequelize - 引用同一个表主键的外键 [英] Sequelize - Foreign key that references same table primary key

问题描述

是否可以在 Sequelize 模型语法中构建以下内容?用途是您想要嵌套数据.

Is it possible to construct the following in Sequelize model syntax? The use being you want to have nested data.

CREATE TABLE Data
(
    `id` INT AUTO_INCREMENT PRIMARY KEY,
    ...
    `parentId` INT,
    FOREIGN KEY(parentId) REFERENCES Data(id)
);

是的

const Data = sequelize.define('Data', {
    id: {
        type: Sequelize.INTEGER,
        primaryKey: true,
        autoIncrement: true,
    },
})

Data.belongsTo(Data, { foreignKey: 'id' });

推荐答案

看来你可以！

const Data = sequelize.define('Data', {
    id: {
        type: Sequelize.INTEGER,
        primaryKey: true,
        autoIncrement: true,
    },
})

Data.belongsTo(Data, { foreignKey: 'id' });
