sequelize搭建模型代码

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 = {};
 
let sequelize;
if (config.use_env_variable) {
    sequelize = new Sequelize(process.env[config.use_env_variable]);
} else {
    sequelize = new Sequelize(
        config.database, config.username, config.password, config
    );
}
 
fs
    .readdirSync(__dirname)
    .filter((file) =>
        (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);
    }
});
 
db.sequelize = sequelize;
db.Sequelize = Sequelize;
 
module.exports = db
