There's nothing wrong with your code, it's working perfectly. But if
you want to iterate the array, there are several ways.
Most commonly, you can use ".each":
<% array = ['a','b','c'] %>
<% array.each do |element| %>
<%= element %>
<% end %>
but if the format you've noted is specific ("a,b,c") then you can use
the ".join" method:
<% array = ['a','b','c'] %>
<%= array.join(", ") %>
I would recommend having a play with the Enumerable and Array API pages:
http://ruby-doc.org/core/classes/Enumerable.html
http://ruby-doc.org/core/classes/Array.html
Rails add more functionality to these, but getting a grasp on the Ruby
will help.
