Ruby each loop separate by commas

Question

I am trying to get this loop to separate the results by a comma:

<% @regions.each do |region| %>
  <%= link_to region.name, region_path(region) %>
<% end %>

If I do this, it adds a comma after the last result:

<% @regions.each do |region| %>
  <%= link_to region.name, region_path(region) %>,&nbsp;
<% end %>

There must be an elegant way.

Answer 1

<%= safe_join(@regions.map { |region| link_to(region.name, region_path(region)) }, ', ') %>
