title: kaminari undefined method `total_pages'
body: <p>While using kaminari, I got an error.</p>
  
  <p>Gemfile:</p>
  
  <pre><code># gem 'will_paginate', '~&gt; 3.0.6'
  # gem 'will_paginate-bootstrap'
  
  gem 'kaminari'
  </code></pre>
  
  <p>lists_controller.rb</p>
  
  <pre><code>  def index
      if params[:tag]
        @lists = List.tagged_with(params[:tag]).order(created_at: :desc).paginate(page:params[:page], per_page: 3 )
      else
        @lists = List.all.order(created_at: :desc)
      end
    end
  </code></pre>
  
  <p>I also user <code>.page params[:page].per(2)</code> follow <code>.order(created_at: :desc)</code>
  but not work</p>
  
  <p>views/lists/index.html.erb</p>
  
  <pre><code>&lt;%= paginate @lists %&gt;
  </code></pre>
  
  <p>the error is here</p>
  
  <pre><code>undefined method `total_pages' for #&lt;List::ActiveRecord_Relation:0x007fa2303e3fa8&gt;
  Extracted source (around line #26):             
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;%= paginate @lists %&gt;
    &lt;div class="container"&gt; 
      &lt;div class="row"&gt;
        &lt;div class="col-md-8"&gt;
  </code></pre>
  
  <p>I was following a railscasts video about kaminari, but they did not have any error.</p>
