# Now you can render cms_page simply by calling:
# render cms_page: '/path/to/page'
# This way application controllers can use CMS content while populating
# instance variables that can be used in partials (that are included by
# by the cms page and/or layout)
#
# Or how about not worrying about setting up CMS pages and rendering
# application view using a CMS layout?
# render cms_layout: 'layout_slug', cms_fragments: {
# fragment_identifier_a: 'content text',
# fragment_identifier_b: {template: 'path/to/template' },
# fragment_identifier_c: {partial: 'path/to/partial' }
# }
#
# This way you are populating page block content and rendering
# an instantialized CMS page.
#
# Site is loaded automatically based on the request. However you can force
# it by passing :cms_site parameter with site's slug. For example:
# render cms_page: '/path/to/page', cms_site: 'default'
