This Rails Cells example demonstrates how to: * access the request * access the controller * access the session * access the request parameters * cache data * use dynamic cache keys * access cell parameters * use helpers

class MenuCell < Cell::Rails
  helper :menu
  cache :display, :cache_conf, :expires_in => 1.day

  def display
    @selected = options[:selected]
    @posts ||= Post.paginate(options[:posts])
    render
  end

  protected
    def cache_conf
      # parent_controller.controller_name
      # parent_controller.request or request
      # parent_controller.session
      # parent_controller.params
      { :path => request.fullpath }
    end
end

The cell is rendered by calling:

<%= render_cell :menu, :display, :selected => controller.controller_name %>

See Cells the change log for details.
