Batch.sync().then((res) => { console.log("Batch model sync : ", Batch === sequelize.models.Batch);});但我需要改变studentIds: { type: DataTypes.ARRAY(DataTypes.STRING)}每当我进行此更改时,它都会出错我正在使用节点 14.5.0 MySql 8.0.21 和 Sequelize 6.3.4 1 回答 宝慕林4294392 TA贡献20...

在使用Sequelize库中,可通过belongsToMany方法做关联: const Student = sequelize.define('Student', { name: DataTypes.STRING }); const Course = sequelize.define('Course', { name: DataTypes.STRING }); const StudentCourse = sequelize.define('StudentCourse', { studentId: { type: DataTypes.INTEGER, ...
const Student = sequelize.define('Student', { name: DataTypes.STRING }); const Course = sequelize.define('Course', { name: DataTypes.STRING }); const StudentCourse = sequelize.define('StudentCourse', { studentId: { type: DataTypes.INTEGER, ...
ARRAY An array oftype, e.g.DataTypes.ARRAY(DataTypes.DECIMAL) This is an extract from theSequelize ES6 Cheatsheet the better Sequelize docs you wish you had (get ithere). Photo by Mika Baumeister
定义多态关联:使用Model.belongsTo方法定义模型之间的多态关联,例如:const Comment = sequelize.define('Comment', { content: { type: DataTypes.STRING, allowNull: false } }); User.hasMany(Comment); Comment.belongsTo(User);以上代码定义了一个名为Comment的模型,包含了content字段,且不能为...

const DataTypes = Sequelize.DataTypes; const user = sequelize.define('u', { userId: { type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true }, userName: { type: DataTypes.STRING, allowNull: true }, birthDay: { type: 'TIMESTAMP', ...
