Rails Pagination with the Kaminari Gem - カミナリジェム

Jun 19, 2020

Welcome to Your SEO Geek, one of the top SEO agencies in Buffalo, specializing in digital marketing services. In this article, we will dive into the topic of Rails pagination and how you can leverage the power of the Kaminari gem to enhance the user experience on your website.

Why Pagination Matters

Pagination plays a crucial role in improving website usability and user experience. When content is presented in chunks, it becomes easier for users to navigate and find the information they need. It also helps in reducing page load time and optimizing server resources, ultimately increasing overall website performance.

Introducing the Kaminari Gem

The Kaminari gem is a popular pagination library for Ruby on Rails applications. With its robust features and easy integration, it has become the go-to choice for developers looking to implement pagination efficiently. Let's explore some of the key features that make the Kaminari gem stand out:

Flexible Integration

Kaminari seamlessly integrates with ActiveRecord and other popular ORMs, making it a breeze to paginate database records. With just a few lines of code, you can enable pagination and start reaping the benefits.

Customization Options

The gem offers a wide range of customization options, allowing you to tailor the pagination to match your website's design and requirements. You can easily customize the appearance, such as the pagination links, the number of items per page, and more.

Efficient Pagination Algorithms

Kaminari implements efficient pagination algorithms, ensuring smooth performance even when dealing with large datasets. It offers support for various pagination strategies like offset-based and keyset-based pagination, empowering developers to choose the most suitable approach for their specific needs.

Implementing Kaminari Pagination in Your Rails App

Now that we understand the benefits and features of the Kaminari gem, let's dive into implementing pagination in your Ruby on Rails application. Follow the steps below to get started:

Step 1: Install the Kaminari Gem

To begin, open your Gemfile and add the following line:

gem 'kaminari'

Save the file and run the bundle command to install the gem:

$ bundle install

Step 2: Configure Pagination

Once the gem is installed, you need to configure it in your Rails application. Open the config/initializers/kaminari_config.rb file and customize the settings according to your requirements.

Step 3: Paginate Your Model

To paginate a specific model, add the paginate method to your controller's action:

@items = Item.paginate(page: params[:page], per_page: 10)

In this example, we are paginating the Item model, displaying 10 items per page.

Step 4: Display Pagination Links

In your view template, you can display the pagination links using the paginate helper method. For instance:

This will generate the necessary HTML markup for the pagination links, allowing users to navigate through the pages.


Implementing pagination in your Rails application is a key aspect of enhancing the user experience and optimizing your website's performance. The Kaminari gem provides a comprehensive solution with its flexible integration, customization options, and efficient pagination algorithms.
