Paginate::Responder

A Rails pagination responder with link header support.

Add this line to your application's Gemfile:

gem 'paginate-responder'

And then execute:

bundle

Or install it yourself as:

gem install paginate-responder

You will also need a pagination gem. PaginateResponder comes with adapters for

• will_paginate,
• kaminari, and
• pagy.

It is recommended to use only one pagination gem at once.

Add Responders::PaginateResponder to your responder chain:

class AppResponder < Responder
  include Responders::PaginateResponder
end

class MyController < ApplicationController
  self.responder = AppResponder
end

Or use it with plataformatec/responders:

class MyController < ApplicationController
  responders Responders::PaginateResponder
end

PaginateResponder will add the following link headers to non HTML responses:

• first First page's URL.
• last Last page's URL.
• next Next page's URL.
• prev Previous page's URL.

next and prev page links will not be added if current page is first or last page.

Additionally, a X-Total-Pages header will be added with the total number of pages if available and a X-Total-Count header with the total number of items. This allows applications to display a progress bar or similar while fetching pages.

You can override the page detection by creating a method page in your controller that returns the page index as a numeric:

class ApplicationController
  def page
    params[:seite].to_i # seite means page in German
  end
end

The same applies to per_page and max_per_page:

class ApplicationController
  def per_page
    10
  end

  def max_per_page
    25
  end
end
