Notifications

Just add JSON on HTML notifications in your Rails app

gem 'notifications'

How it works

This gem helps you to get rid of this bunch of a code

<%= form_for(@resource) do |f| %>
  <% if @resource.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@resource.errors.count, "error") %> prohibited this resource from being saved:</h2>

      <ul>
      <% @resource.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  # ....

<% end %>

and replace it with the following code:

  - form_for(@post) do |f|
    = render partial: 'notifications/form', locals: { object: @post }

and this code to render Flash messages:

body
  = render partial: 'notifications/flash'
  = yield

How to use

Note: toastr is an external dependency for format: :json case. Download and and install it yourself. vendors/toastr is just a demo path to assets

application.css

/*
  //= require notifications/base
*/

application.js

//= require notifications/base

application_initializer.js

$ ->
  do Notifications.init

Format html or json

You can select a way how to render notifications. There are 2 options: format: :html and format: :json

= render partial: 'notifications/flash', locals: { format: :html }
= render partial: 'notifications/form', locals: { object: @post, format: :json }

Default notifications format

initializers/notifications.rb

Notifications.configure do |config|
  config.default_type = :json # :html
end

Errors' localization

To avoid this case

Title: не может быть пустым

Do the following steps:

models/user.rb

class Post < ActiveRecord::Base
  include ::Notifications::LocalizedErrors
end

config/locales/ru.yml

activerecord:
  models:
    post: Публикация
  attributes:
    post:
      title: "Загловок"

Now errors messages will look so:

Загловок: не может быть пустым
