RenderAsync

Renders partials to your views asynchronously. This is done through adding Javascript code that does AJAX request to your controller which then renders your partial.

Workflow:

1. user visits a page =>
2. AJAX request on the controller action =>
3. controller renders a partial =>
4. partials renders in the place where you put render_async helper

Javascript is injected into <%= content_for :render_async %> so you choose where to put it.

Installation

Add this line to your application's Gemfile:

gem 'render_async'

And then execute:

$ bundle install

Usage

1. Include render_async view helper somewhere in your views:

   # app/views/comments/show.html.erb
   
   <%= render_async comment_stats_path %>
   

2. Then create a route that will config/routes.rb

   # config/routes.rb
   
   get :comment_stats, :controller => :comments
   

3. Fill in the logic in your controller

   # app/controllers/comments_controller.rb
   
   def comment_stats
     @stats = Comment.get_stats
   
     render :patial => "comment_stats"
   end
   

4. Create a partial that will render

   # app/views/comments/_comment_stats.html.erb
   
   <div class="col-md-6">
     <%= @stats %>
   </div>
   

5. Add content_for in your base view file

   # application.html.erb
   
   <%= content_for :render_async %>
