Nivo Slider with Ruby on Rails

Nivo Slider is one of the most popular JavaScript slider. This gem provides integration with Ruby on Rails.

Installation

First, add this to your Gemfile:

gem 'nivo-rails'

# If you are running Rails 5.1+, jQuery might not be a dependency
# of your project but it's still needed for Nivo Slider to run.
gem 'jquery-rails'

Then run the bundle command to install the gem.

Usage

This gem provides files required to setup correctly Nivo Slider on your site. It requires a few lines of code to setup a slideshow. First, make sure to import the CSS file:

/* Inside a normal application.css file
 *= require nivo
 */

// Or if you are using Sass/SCSS
@import "nivo";

And then import the JavaScript file as well:

//= require nivo

You can now easily add slideshows in your web pages. To avoid writing all the boilerplate needed by Nivo Slider, you can rely on the nivo_slider tag:

<%= nivo_slider id: "slider" do %>
  <%= image_tag "foo.png", title: "A very nice photo!" %>
  <%= image_tag "bar.png" %>
<% end %>

This helper behaves like Action View's content_tag helper apart from the fact that it doesn't escape the provided content by default. It also sets the div's id to "slider" by default and adds a nivoSlider class as well.

If you want to set a theme, you should wrap the nivo_slider call with a div element with the proper class:

<div class="theme-dark">
  <%= nivo_slider id: "slider" do %>
    <!-- ... -->
  <% end %>
</div>

Make sure then to initialize Nivo Slider on the given element:

$(window).on('load', function() {
  $('#slider').nivoSlider();
});

// Or if you are using Turbolinks
$(document).on('turbolinks:load', function () {
  $('#slider').nivoSlider();
});

Enjoy!
