Overview

Page renderer renders data from dc_page collection documents. This renderer will almost certainly be replaced by your own renderer so example here shows just basic code which just checks if user is allowed to view data and if so returns document body content otherwise returns error message defined in site policy.

Example:

<div id="page">
  <%= dc_render(:dc_page) %>
</div>
