I got a model folder which contains all sequelize schema models, and I tried to write an index.js in this model folder; but when I run the app, there is an error "sequelize is not defined" in the index.js. Please see my codes below.
"use strict";
const fs = require("fs");
const path = require("path");
const Sequelize = require("sequelize");
const basename = path.basename(module.filename);
const env = process.env.NODE_ENV || "development";
const config = require(__dirname + "/../config/config.json")[env];
const db = {};
if (config.use_env_variable) {
const sequelize = new Sequelize(process.env[config.use_env_variable]);
} else {
const 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 = sequelize["import"](path.join(__dirname, file));
db[model.name] = model;
});
Object.keys(db).forEach((modelName) => {
if (db[modelName].associate) {
db[modelName].associate(db);
}
});
sequelize
.authenticate()
.then(() => {
console.log("Connection has been established succesfully");
})
.catch((err) => {
console.log("Unable to connect to the database:", err);
})
db.sequelize = sequelize;
db.Sequelize = Sequelize;
db.group = require('./group')(sequelize, Sequelize);
db.service = require('./service')(sequelize, Sequelize);
db.store = require('./store')(sequelize, Sequelize);
db.appointment = require('./appointment')(sequelize, Sequelize);
module.exports = db;
