Create not found when using Sequelize CLI generated model - postgresql

Question

My approach was like this below command
npx sequelize-cli model:generate --name User --attributes name:string,email:string,password:string
then it's generated a model file named user.js & file structure like below
'use strict';
const {
Model
} = require('sequelize');
module.exports = (sequelize, DataTypes) => {
class User extends Model {
/**
* Helper method for defining associations.
* This method is not a part of Sequelize lifecycle.
* The `models/index` file will call this method automatically.
*/
static associate(models) {
// define association here
User.hasMany(models.Course, {
foreignKey: 'userId'
})
}
};
User.init({
name: DataTypes.STRING
}, {
sequelize,
modelName: 'User',
});
return User;
};
also, created the Users table with columns.
And the index.js file like below which automatically generated
'use strict';
// main model file
const fs = require('fs');
const path = require('path');
const Sequelize = require('sequelize');
const basename = path.basename(__filename);
const env = process.env.NODE_ENV || 'development';
const config = require(__dirname + '/../config/config.json')[env];
const db = {};
let sequelize;
if (config.use_env_variable) {
sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
sequelize = new Sequelize(config.database, config.username, config.password, config);
}
fs
.readdirSync(__dirname)
.filter(file => {
return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
})
.forEach(file => {
const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
db[model.name] = model;
});
Object.keys(db).forEach(modelName => {
if (db[modelName].associate) {
db[modelName].associate(db);
}
});
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
and when I try to create a user like the below codes
import { User } from '../../../../models'
try {
await User.create({
name: 'john doe',
email: 'john#gmail.com'
})
res.json({"message": "create"})
} catch (error) {
res.send(error.message)
}
it's showing
Cannot read property 'create' of undefined
what I have done wrong here?
Can you please help me out with that?
Thanks

replace this code in models/index.js for printing database successfully connected or not.
'use strict';
const fs = require('fs');
const path = require('path');
const Sequelize = require('sequelize');
const basename = path.basename(__filename);
const env = process.env.NODE_ENV || 'development';
const config = require(__dirname + '/../../config/config.js')[env];
const db = {};
let sequelize;
if (config.use_env_variable) {
sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
sequelize = new Sequelize(config.database, config.username, config.password, config);
}
//for checking database successfully connected or not
sequelize
.authenticate()
.then(() => {
console.log('Connection has been established successfully.');
})
.catch(err => {
console.error('Unable to connect to the database:', err);
});
fs
.readdirSync(__dirname)
.filter(file => {
return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
})
.forEach(file => {
const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
db[model.name] = model;
});
Object.keys(db).forEach(modelName => {
if (db[modelName].associate) {
db[modelName].associate(db);
}
});
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
Then try to importing like this.
const admin = require("../../database/models").tbl_admin;
try {
await admin.create({
name: 'john doe',
email: 'john#gmail.com'
})
res.json({"message": "create"})
} catch (error) {
res.send(error.message)
}
