This is a basic Ruby question. You might want to look into buying a
primer on Ruby and learn the basics; it'll help you a lot.
<% @hash.each do |key, value| %>
<%=h "#{key.to_s} #{value.to_s}" %>
<% end %>
You can iterate through hashes in many various ways, including sorting them:
<% @hash.keys.sort.each do |key| %>
<%=h "#{key.to_s} #...@hash[key]}" %>
<% end %>
If these are controlled by someone not you (that is, submitted by the
user) using <%=h ... %> ensures that any HTML contained within would
not render directly into the page, but instead convert < into < and
so on. This is a basic security measure.
