Audit logs and posts can run into thousands quickly, so we need pagination to help users navigate from page to page. To do that, we are going to use a gem called Kaminari, I personally like this gem because it gives a Javascript type of implementation, which means, you'll never have to leave the page while paginating.

Open your gemfile and copy this:

# Gemfile

gem 'kaminari', '~>0.17.0'

Then run bundle.

Next, let's start our pagination from posts. Go to the posts index page and put this code at the bottom of the file.

<!-- app/views/posts/index.html.erb -->

<%= paginate @posts %>

Then open the posts_controller.rb and add this method call:

# app/controllers/posts_controller.rb

def index
  @posts = Post.posts_by(current_user).page(params[:page]).per(10)
end

Open the browser now, and it's all working!

We're going to do the exact same thing for audit log too. Open audit_log_controller.rb and add this code:

# app/controllers/audit_logs_controller.rb

class AuditLogsController < ApplicationController
  def index
    @audit_logs = AuditLog.page(params[:page]).per(10)
    authorize @audit_logs
  end
end

Likewise, include the <%= paginate @audit_logs %> code at the very end of the audit log's index file.

Now, the audit log has a fully functioning pagination feature as well.
