Association in Sequelize throwing error as <model1> not connected to <model2> - mysql

Question

I am new to the database and learning sequelize (Postgres). I am building a blogging web app and trying to implement association in my DB but getting a server-side error as
error: creator is not associated with blogpost
here is what I have done till now.
creator_model
const Sequelize = require('sequelize');
const db = require('../db/dbConfig');
const bcrypt = require('bcrypt');
const Creator = db.sequelize.define('creator', {
id: {
type: Sequelize.INTEGER,
primaryKey: true,
autoIncrement: true,
allowNull: false
},
firstName: {
type: Sequelize.STRING,
allowNull: false
},
lastName: {
type: Sequelize.STRING
},
email: {
type: Sequelize.STRING,
allowNull: false,
unique: true
},
password: {
type: Sequelize.STRING,
allowNull: false
}
},
{
hooks: {
beforeCreate: (Creator) => {
Creator.password = bcrypt.hashSync(Creator.password,10)
}
}
}
);
Creator.associate = (models) => {
console.log('visited here')
Creator.hasMany(models.BlogPost,{
foreignKey: "creatorId",
as: "owner",
onDelete: 'CASCADE'
});
}
module.exports = Creator;
Blog_model
const Sequelize = require('sequelize');
const Creator = require('../models/CreatorModel');
const db = require('../db/dbConfig');
const BlogPost = db.sequelize.define('blogpost',{
blogId: {
type: Sequelize.INTEGER,
primaryKey: true,
autoIncrement: true,
allowNull: false
},
title: {
type: Sequelize.STRING,
allowNull: false
},
cover: {
type: Sequelize.STRING,
allowNull: false
},
body: {
type: Sequelize.TEXT,
allowNull: false
},
creatorId: {
type: Sequelize.INTEGER,
references:{
model: Creator,
key: 'id'
},
allowNull: false
},
likes: {
type: Sequelize.INTEGER,
defaultValue: 0
}
},{});
BlogPost.associate = (models) => {
BlogPost.hasMany(models.Comment,{
foreignKey: 'postId',
as: 'blogpost',
onDelete: 'CASCADE'
});
BlogPost.belongsTo(models.Creator,{
foreignKey: 'creatorId',
as: 'creator',
onDelete: 'CASCADE'
})
}
module.exports = BlogPost;
Comment_model
const Sequelize = require('sequelize');
const BlogPost = require('../models/BlogPostModel');
const db = require('../db/dbConfig');
const Comment = db.sequelize.define('comment',{
commentId: {
type: Sequelize.INTEGER,
primaryKey: true,
autoIncrement: true,
allowNull: false
},
name: {
type: Sequelize.STRING,
allowNull: false
},
email: {
type: Sequelize.STRING,
allowNull: false
},
message: {
type: Sequelize.TEXT,
allowNull: false
},
blogPostId: {
type: Sequelize.INTEGER,
references: {
model: BlogPost,
key: 'blogId'
},
allowNull: false
}
},{});
Comment.associate = (models) => {
Comment.belongsTo(models.BlogPost,{
foreignKey: 'blogPostId',
as: 'blog',
onDelete: 'CASCADE'
})
}
module.exports = Comment;
here is my DB config with express and sequelize
const Sequelize = require('sequelize');
const dotenv=require("dotenv");
dotenv.config();
const db ={}
const sequelize = new Sequelize(`${process.env.DB_NAME}`, `${process.env.DB_USERNAME}`, `${process.env.DB_PASSWORD}`, {
host: 'localhost',
dialect: 'postgres'
})
sequelize
.authenticate()
.then(() => {
console.log('Connection has been established successfully.');
})
.catch(err => {
console.error('Unable to connect to the database:', err);
});
db.sequelize = sequelize
db.Sequelize = Sequelize
sequelize.sync()
.then(() => {
console.log(`Database & tables created!`)
})
.catch(error => console.log("DB error: ",error));
module.exports = db;
controller.js
const BlogPost = require('../models/BlogPostModel');
const Comment = require('../models/CommentModel');
const Creator = require('../models/CreatorModel');
const getAllBlog = (req,res) =>{
BlogPost.findAll({
include: [
{
model: Creator,
as: "author",
include: [{
model: Comment,
as: "comments"
}]
}
]
})
.then(data => {
res.json(data)
})
.catch(error => {
res.status(500).json({error: error.message})
})
}
module.exports = {
getAllBlog
}
