const { DataTypes } = Sequelize;   
const Users = db.define('users',{
    id:{
        type: DataTypes.INTEGER,
        autoIncrement: true,
        primaryKey: true
    },

Blog model

import Users from "./UserModel.js";
 
const { DataTypes } = Sequelize;
 
const Blogs = db.define('blog',{
    id:{
        type: DataTypes.INTEGER,
        autoIncrement: true,

    },
    title:{

    },
});
Blogs.associate = function() {
    Blogs.belongsTo(Users, {
        foreignKey: 'created_by'
    })
}
 
export default Blogs;

I keep getting the error 'users is not associated to blog'. Can you please guide me where I am making the mistake?

You need to register all associations after all models will be registered. See my other answer to get an idea how to do it.
