title: TinyMCE and ActiveAdmin for Rails
body: <p>I am reacquainting myself with Rails and I am really liking Active Admin.  I would like to get tinyMCE working with it for use in text areas.  However, any instructions I find are incomplete.  For some reason, I think that I am missing something really simple here.</p>
  
  <p>So, for example, I have tinymce-rails installed (3.4.9) and followed the instructions (https://github.com/spohlenz/tinymce-rails).  However, here's where I think I failed:  actually initiating tinyMCE.  According to the doc, I have two options:</p>
  
  <ol>
  <li>use the &lt;%= tinymce %> helper or...</li>
  <li>initialize it like the following <code>tinyMCE.init({
  mode: 'textareas',
  theme: 'advanced'
  });</code></li>
  </ol>
  
  <p>I tried adding the latter to my active_admin.js file to no avail.</p>
  
  <p>If someone could guide me on this, I would be most appreciative.</p>
