title: Paginating an Array in Ruby with will_paginate
body: <p>I have an array @level1 which looks like this :</p>
  
  <pre><code>[[3.0, 4, 2], [2.0, 48, 3], [2.1, 56, 4], ............]
  </code></pre>
  
  <p>I want to apply pagination on this array such each page displays only a few rows at once. I tried this:</p>
  
  <pre><code>@temp1 = @level1.paginate(:page =&gt; params[:page])
  </code></pre>
  
  <p>But it throws the following error: </p>
  
  <pre><code>undefined method `paginate' for [[3.0, 4, 2], [2.0, 48, 3], [2.1, 56, 4]]:Array
  </code></pre>
  
  <p>How can I perform pagination on this using will_paginate?</p>
