Question

Now I’m trying to make path markup.

Assume it’s up to 4th depth level directory then I made something like this for view?
How can I pass the path to view from controller with variable label???

          <% if !@FirstDirPath.nil? %>
          <%= @FirstDirPath %> <span class="divider">/</span>
          <% end %>

          <% if !@SecondDirPath.nil? %>
          <%= @SecondDirPath %> <span class="divider">/</span>
          <% end %>

          <% if !@ThirdDirPath.nil? %>
          <%= @ThirdDirPath %> <span class="divider">/</span>
          <% end %>

          <% if !@FourthDirPath.nil? %>
          <%= @FourthDirPath %> <span class="divider">/</span>
          <% end %>

You can access the current path with request.fullpath

If you want to get the breadcrumb then you can just split the fullpath by ‘/’. In the controller:

@path = request.fullpath
@breadcrumb = @path.split('/')

In the view:

<% @breadcrumb.each do |crumb| %>
  <%= crumb %>
  <span class="divider">/</span>
<% end %>

Untested, but I think it should work.
