Anchor while itering - Rails - ruby-on-rails

Question

I am trying to make an anchor in an index page while itering through a list of elements.
On the home page I display each element with a 'more info' button. When clicked it goes to the index of detailed elements. I tried the code below, but it doesn't work.
link_to 'More info', tours_path(#tour, :anchor => "#{tour.name}"
I also tried, without success:
link_to 'More info', tours_path(#tour, :anchor => tour.name
Here is the code of home.html.erb :
<section id="walking-tours">
<h2 class="text-center">Lisbon walking tours </h2>
<div class="walking-tours d-flex">
<% #tours.each do |tour| %>
<div class="walking-tours-cards item">
<% photo = tour.photos[0] %>
<%= cl_image_tag photo.key, height: 300, width: 300, crop: :fill if tour.photos.attached? %>
<h3> <%= tour.name %> </h3>
<p> <%= tour.description %> </p>
<%= link_to 'More info', tours_path(#tour, :anchor => "#{tour.name}"), class: 'btn btn-outline-secondary' %>
</div>
<% end %>
</div>
</section>
and the code in index.html.erb
<div class="index-tours">
<div class="tours-title">
<h1 >WALKING TOURS</h1>
</div>
<div class="tours-list">
<% #tours.each do |tour| %>
<div class="walking-tours-details ">
<div class="walking-tours-info">
<h3> <%= tour.name %> </h3>
<p> <%= tour.full_information %> </p>
<p><b>Duration</b> -<%= tour.duration %> </p>
<p><b>Meeting Point</b> - <%= tour.meeting_point %> </p>
</div>
<div class="tours-pics">
<% tour.photos.each do |photo| %>
<%= cl_image_tag photo.key, height: 220, width: 220, crop: :fill, :class => "tours-img" %>
<% end %>
</div>
</div>
<% if logged_in? %>
<%= link_to 'Edit', edit_tour_path(tour), :class => "tours-links" %> <%= link_to 'Destroy', tour, method: :delete, data: { confirm: 'Are you sure?' } %>
<% end %>
<% end %>
</div>
For now, all 'more info' buttons go to the first element of the list (at the top of the index page).
Any idea to help? Thanks!!

I found a solution by generating a dynamic ID:
<% tour_link = tour.name %>
<% tour_identification = tour_link.gsub(/\s+/, '') %>
<div id= <%= tour_identification %> >
and for the link_to :
<%= link_to 'More info', tours_path(tour, anchor: tour_identification) %>
But I still wonder if the anchor could work without an ID.
