Hàm sync setup model viết 1 lần thôi bạn. Chạy lúc đầu.
Ex:
models/users.js
export const User = sequelize.define('User', {
id: {autoIncrement: true, primaryKey: true, type: DataTypes.INTEGER}
})
models/project.js
export const Project = sequelize.define('project', {
id: {autoIncrement: true, primaryKey: true, type: Sequelize.INTEGER},
created_by: { type: Sequelize.INTEGER }
})
model/sync.js
import { User } from './user'
import { Project } from './project'
export function sync() {
return new Promise((resolve, reject) => {
User.hasMany(Project, {foreignKey: 'created_by'})
Project.belongsTo(User, {foreignKey: 'created_by'})
resolve('Done Sync Data')
})
}
main.js
import { sync } from 'models/sync'
sync().then(msg => run server)
