UserNotif

Gem Version Build Status Coverage Status Code Climate security

TODO

Add belongs_to custom model (add this in initializer and load it like this belongs_to UserNotif.model_name... in notif.rb)

Installation

Add this line to your application's Gemfile:

gem 'user_notif'

And then execute:

$ bundle

After you install UserNotif and add it to your Gemfile, you need to run the generator:

rails generate user_notif:install

The UserNotifs belong to a user. To ensure it works, make sure you have a User model


If you want to use it out of the box, require JS and SCSS files

In your app/assets/stylesheets/application.css

/*
 *= require user_notif
 */

In your app/assets/javascripts/application.js

//
//= require user_notif
//

Do not forget to restart your server to load the new assets.

Usage

Now you can create your first notification !

Models

Run this generator:

rails generate user_notif name target_model

It will create a NameNotif model and his associated views. You should customize the generated views.

A notification has a user and a target. The target can be any model, like a User or something else. You can then override the views to display informations about the target.

Example:

rails generate user_notif new_follower user

It creates a NewFollowerNotif

Now you can add the logic to create notifications when a user is followed by another one (the target).

Example:

NewProjectNotif.create(target: self, user: self.user)

To create sticky notifs (notification staying on top of the list), you can add sticky: true when you create it. Like this:

NewProjectNotif.create(target: self, user: self.user, sticky: true)

Then, you can display it in your view like this: <%= list_user_notifs(UserNotif::Notif.all.order(sticky: :desc, unread: desc, id: :desc)) %> This line of code will display notifications by sticky first, then unread, then by id.

Views

To display your notifications, you can use some helpers:

list_user_notifs(notifs, small = true)

user_notif(notif, small = true)

<%= list_user_notifs(UserNotif.all) %>
<%= user_notif(UserNotif.last, false) %>

The small parameter will take care of rendering the partial located in app/views/notifs/[small,full]

You can also use the notif_badge helper to display a badge with the number of unread notifications.

<%= notif_badge(UserNotif.unread) %>

Cutomizing your views

You can customize your views by modifying app/views/notifs/[small,full]/* files.

Implement your own element to mark notifications as read with mark-as-read class.

An ajax call to the data-url is triggered when you click on this element. This makes the notification read !

Example:

<div class=user-notif">
  ...
  <div class="mark-as-read" data-url="<%= read_user_notif_path(id: @notif.id) %>">X</div>
</div>

The default behavior remove the unread class on the element itself but you can override it or add your own behavior.

Mailer

Every notification sends a mail by default. You can override this in your generated model: app/models/notifs/your_notif.rb

The mailer views are located at app/views/notifs/mailer/your_notif.[html,text].erb

You can customize the mailer by providing options in your generated initializer (install step):

# config/initializers/user_notif.rb

UserNotif.setup do |config|
  config.app_name = 'My App'
  config.mailer_sender = 'no-reply@myapp.com'
  config.mailer_bcc = 'admin@myapp.com'
  config.mailer_cc = 'admin@myapp.com'
  config.mailer_reply_to = 'admin@myapp.com'
  config.mailer_date = Date.current
  config.return_path = 'contact@myapp.com'
end

By modifying the initializer, all your notification mailers will default to this. You can still provide custom values per notification by overriding the method email_options in your generated model.

This method should look like this:

# app/models/notifs/your_notif.rb
...
def email_options
  super({
      subject: I18n.t('awesome.18n.key'),
      cc: @coworker.email,
      bcc: @president.email
    })
end

The super ensures default values are loaded.

If you want to customize the mailer behaviour, you can re-open the class at app/mailers/user_notif/notif_mailer.rb. For example, If you want to use another mail generator (such as Roadie) alongs with i18n and the Rails URL helpers or even add a layout to your emails, it would give something like this :

# app/mailers/user_notif/notif_mailer.rb

class UserNotif::NotifMailer
  include Roadie::Rails::Automatic
  include DefaultUrlOptions
  include Rails.application.routes.url_helpers

  layout 'mailer'
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
