Page specific metadata

You may encounter situations where you want to add content to a particular page (or other model) in a way that doesn't involve changing the database structure or creating new block kinds. One way to do this is storing the information in the record's blockable_metadata column. The following examples show how to add a special description and video URL field to a page named "Home".

# page_decorator.rb

Page.class_eval do
  store_accessor :blockable_metadata, :home_page_description, :home_page_video_url
end

<%# admin/pages/_additional_inputs.html.erb %>

<% if @page.try(:slug).present? %>
  <% begin %>
    <%= render "#{@page.slug}_page_settings", f: f %>
  <% rescue ActionView::MissingTemplate => e %>
    <% logger.info  { "[Forest][Info] No additional page settings template found for #{@page.slug}" } %>
  <% end %>
<% end %>

<%# admin/pages/_home_page_settings.html.erb %>

<div class="panel panel-default" data-collapse-parent>
  <div class="panel-heading">
    <h3 class="panel-title">
      Home Page Settings
      <button type="button" class="btn btn-default btn-xs pull-right" data-collapse-trigger>
        <div class="collapsable-icon glyphicon glyphicon-chevron-up"></div>
      </button>
    </h3>
  </div>
  <div class="panel-body" data-collapse-body>
    <div class="form-inputs">
      <div class="row">
        <div class="col-sm-12">
          <%= f.input :home_page_video_url %>
          <%= f.input :home_page_description %>
          <%= f.button :submit, class: 'btn-success' %>
        </div>
      </div>
    </div>
  </div>
</div>
