Render a section outside the Maglev layout

Some pages are not fully managed in the Maglev editor—for example, a Rails product detail template that still needs your navbar and footer from Maglev.

For that, the engine provides a controller concern so you can render_maglev_section outside the Maglev theme layout.

Content for those sections is still edited in the Maglev editor (for example as site-scoped navbar/footer blocks). The standalone template only renders the current published output.

Inside your Rails controller

Include the engine’s Maglev::StandaloneSectionsConcern in the controller that serves the page (or in ApplicationController).

Example for a product page:

app/controllers/products_controller.rb
class ProductsController < ApplicationController
  include Maglev::StandaloneSectionsConcern # methods required to load site-scoped sections

  def show
    fetch_maglev_site_scoped_sections # loads all site-scoped sections for this request
    @product = Product.find(params[:id])
  end
end

To load site-scoped sections on every request:

app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  include Maglev::StandaloneSectionsConcern # methods required to load site-scoped sections

  before_action :fetch_maglev_site_scoped_sections
end

Inside your ERB template

app/views/products/show.html.erb
<%= render_maglev_section :navbar %>

<div>
  <h1><%= @product.name %></h1>
  <p>Price: <%= number_to_currency @product.price %></p>
</div>

<%= render_maglev_section :footer %>
