| module LayoutsHelper | |
| # Used to achieve nested layouts without content_for. This helper relies on | |
| # Rails internals, so beware that it make break with future major versions | |
| # of Rails. Inspired by http://stackoverflow.com/a/18214036 | |
| # | |
| # Usage: For example, suppose "child" layout extends "parent" layout. | |
| # Use <%= yield %> as you would with non-nested layouts, as usual. Then on | |
| # the very last line of layouts/child.html.erb, include this: | |
| # | |
| # <% parent_layout "parent" %> | |
| # | |
| def parent_layout(layout) | |
| @view_flow.set(:layout, output_buffer) | |
| output = render(template: "layouts/#{layout}") | |
| self.output_buffer = ActionView::OutputBuffer.new(output) | |
| end | |
