Ruby on rails - Database design to store notifications to users

To design a database schema for storing notifications to users in a Ruby on Rails application, you can create a Notification model that belongs to a User. Here's how you can set it up:

  1. Create a Notification Model:

    Generate a new model for notifications:

    rails generate model Notification user:references message:text read:boolean

    This will generate a migration file and a model file for the Notification model with a user_id reference to the User model, a message field to store the notification message, and a read field to track whether the notification has been read or not.

  2. Run the Migration:

    Run the migration to create the notifications table in the database:

    rails db:migrate

  3. Define Associations:

    In your User model (app/models/user.rb), define the association:

    class User < ApplicationRecord has_many :notifications, dependent: :destroy end

    And in your Notification model (app/models/notification.rb), define the association and add any necessary validations or methods:

    class Notification < ApplicationRecord belongs_to :user validates :message, presence: true end

  4. Usage:

    You can now create notifications for users and associate them with the respective users:

    user = User.first notification = user.notifications.create(message: "New message received!")

    And you can access a user's notifications:

    notifications = user.notifications

    Additionally, you can mark notifications as read:

    notification.update(read: true)

This is a basic setup to get you started. Depending on your requirements, you might need to add more fields to the Notification model or handle notification delivery and read tracking differently.
