Notifications for Jumpstart Pro are built-in using the Noticed gem and allows delivering notifications across any medium.

Creating Notifications

To generate a new notification, run the following:

rails g noticed:notification NewComment

This will generate the notification as app/notifications/new_comment.rb. The notification file includes comments to help customize the notification message, url, and delivery methods.

Sending Notifications

To deliver a notification to a user, run the following:

Deliver in background (recommended)

NewComment.with(comment: @comment).deliver_later(@comment.post.owner)

Deliver immediately (can be slow)

NewComment.with(comment: @comment).deliver(@comment.post.owner)

This will write the notification to the database and perform any other deliveries that are configured for the notification.


Jumpstart Pro ships with an ApplicationNotification that notifications inherit from. This parent class is responsible for handling anything that all notifications should have just like ApplicationRecord does for your models.

Delivery Methods

Check the Noticed gem's readme to see the full list of delivery methods and how to create your own.

Here are a few of the supported delivery methods:

  • Database
  • Email
  • ActionCable
  • Slack
  • Twilio
  • Vonage

Notifications using the :database delivery method will be rendered in the navbar.

Use the :action_cable delivery method to add notifications to the navbar immediately. Generated notifications include ActionCable as an example by default.

ActionCable notification format

class NewComment < ApplicationNotification
deliver_by :action_cable, format: :to_websocket

def to_websocket
  # Filters notification client side to the user's current account
  # Removing this always renders the notification
  account_id: record.account_id,

  # Used for inserting the notification into the navbar
  html: ApplicationController.render(partial: "notifications/notification", locals: {notification: record}),

  # Used for triggering a native brower Notification API
  # https://developer.mozilla.org/en-US/docs/Web/API/notification
  browser: {
    title: "",
    options: {}

Native browser notifications will only be shown if the user has granted permission.


Notifications have been modified to have an account association on them. This allows you to send notifications to a specific account for a user if you would like.

By default, ApplicationNotification writes the recipient's personal account ID but you can override this by passing in account: recipients_account_to_notify in the notification params. Just make sure the account is one of the recipient's accounts.

Deliver notification to a user's account

NewComment.with(account: @comment.post.account, comment: @comment).deliver_later(@comment.post.owner)

Warning: Do not include acts_as_tenant on the Notification model or you won't be able to create notifications for other users correctly.
