How to make sequalize createTable support underscore? - format

Question

I was trying to use sequalize seed to initialize the table rows, but I got error return:
column "createdAt" of relation "users" does not exist
It actually is "created_at" as the field, so my question is that how can I seed the table with snake or underscore option?
My seed code as following:
"use strict";
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.bulkInsert(
"users",
[
{
firstname: "John",
lastname: "Doe",
email: "demo#demo.com",
createdAt: new Date(),
updatedAt: new Date()
}
],
{}
);
},
down: (queryInterface, Sequelize) => {
return queryInterface.bulkDelete("users", null, {});
}
};

Answer 1

You pass those information while defining your configurations for database connection like below.
'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.json')[env];
const db = {};
let sequelize;
if (config.use_env_variable) {
sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
config.define = {
"timestamps":true,
"createdAt":"created_at",
"updatedAt":"updated_at"
}
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);
}
});
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
Here config is your db configuration. You add other configuration on a separate define

As you can see all in a documentation queryInterface methods work with tables and not models so you should use real column names instead of model props.
