I am trying to relate my Users model with the Posts model, what I want to do is that the user when creating a post saves the post id in the 'posteds' field of the user model, but I can't do it
Post Table:
'posteds' shouldn't be there, it should be in the users table
My relationships:
Users.hasMany(Posts, {foreignKey: 'posteds'})
Posts.belongsTo(Users, {foreignKey : 'userId'})
Model User:
import { DataTypes, UUIDV4, Optional, Model} from "sequelize"
import { connection } from "../database"
import { hash, genSalt, compare } from "bcryptjs";
import Posts from "./posts.model";
export const rolesEnum: string[] = ['ADMIN_ROLE', 'MODERATOR_ROLE','USER_ROLE']
interface UserAttributes{
id: number,
email: string,
password: string,
img_url: string,
role: 'ADMIN_ROLE' | 'MODERATOR_ROLE' | 'USER_ROLE',
created_at: Date,
updated_at?: Date
}
interface UserCreationAttributes extends Optional<UserAttributes, "id" | "created_at" | 'img_url'> {}
// We need to declare an interface for our model that is basically what our class would be
interface UserInstance
extends Model<UserAttributes, UserCreationAttributes>,
UserAttributes {}
const Users = connection.define<UserInstance>('users', {
id: {
type: DataTypes.UUID,
primaryKey: true,
defaultValue: UUIDV4,
unique: true,
allowNull: false
},
email: {
type: DataTypes.STRING,
unique: true,
allowNull: false
},
password: {
type: DataTypes.STRING,
allowNull: false
},
img_url: {
type: DataTypes.STRING,
defaultValue: process.env.DEFAULT_IMAGE || 'default.svg',
allowNull: false
},
role: {
type: DataTypes.STRING,
values: rolesEnum,
defaultValue: 'USER_ROLE',
allowNull: false
},
created_at: {
type: DataTypes.DATE,
defaultValue: DataTypes.NOW,
allowNull: false
},
updated_at: {
type: DataTypes.DATE,
defaultValue: DataTypes.NOW,
}
},{
timestamps: false
})
export default Users
Model Posts:
import { DataTypes, Optional, Model, UUIDV4} from "sequelize";
import {connection} from "../database";
interface PostAttributes {
id: number,
title: string,
description: string,
categorys?: Array<string>,
img_url: string,
created_at: Date,
updated_at?: Date,
userId?: string;
}
interface PostCreationAttributes extends Optional<PostAttributes, "id" | "created_at" |"img_url" | "categorys"> {}
// We need to declare an interface for our model that is basically what our class would be
interface PostInstance
extends Model<PostAttributes, PostCreationAttributes>,
PostAttributes {}
const Posts = connection.define<PostInstance>('posts', {
id: {
type: DataTypes.UUID,
primaryKey: true,
defaultValue: UUIDV4,
unique: true
},
title: {
type: DataTypes.STRING,
allowNull: false
},
description: {
type: DataTypes.STRING,
allowNull: false
},
categorys: {
type: DataTypes.ARRAY(DataTypes.ENUM('web-devlopment', 'recent', 'featured')),
values: ['web-devlopment', 'recent', 'featured'] //HELP TO SEND MESSAGES OF ERROR
},
img_url: {
type: DataTypes.STRING,
allowNull: false,
defaultValue: process.env.DEFAULT_IMAGE || 'default.svg'
},
created_at: {
type: DataTypes.DATE,
defaultValue: DataTypes.NOW,
allowNull: false
},
updated_at: {
type: DataTypes.DATE,
defaultValue: DataTypes.NOW
}
},{
timestamps: false
})
export default Posts
