  #=> <a href="http://example.com" class="btn">Example2</a>
<%= link_to_only_valid_path "Example3", disable_routing_path %>

<%= link_to_only_valid_path enable_routing_path do %>
    <div>innert element</div> 
<% end %>
  #=> <a href="[enable_routing_path]"><div>inner element</div></a>
<%= link_to_only_valid_path disable_routing_path %>
    <div>inner element</div>
<% end %>
  #=> <div>inner element</div> # If the url disable, ignore a link tag.
