Roda ERB active menu helper

[teamschlaflos]

I'd like to create a menu helper function for my ERB templates. My initial thought was to have a menu variable for each route, but then I thought maybe I'd like to avoid to pollute roda route code with that information, but rather keep the decision in an ERB template:

 <a class="nav-link <%= active_if "/section/item1" %>">Item 1</a>
 <a class="nav-link <%= active_if "/section/item2" %>">Item 2</a>

The issue I'm having is that I'm unable to access r in the function:

class App
  # ..
  def active_if(path)
    r.matched_path.start_with?(path) ? 'active' ? ''
  end
end

Can I somehow access r and does anyone have a nice way to handle menus or submenus in an app?

Use request in replace of r. I believe there's also a plugin that will do this for you.

Thanks, that worked! I couldn't make out the correct plugin (plugin list).

Here is the updated version which works for me, without the plugin:

 <a class="nav-link <%= active_if "/section/item1" %>">Item 1</a>
 <a class="nav-link <%= active_if "/section/item2" %>">Item 2</a>

class App
  # ..

  def active_if(path)
    if request.matched_path.start_with?(path)
      'active'
    else
      ''
    end
  end
end

Glad it worked. This is the plugin I was thinking of.
