How to save and display a newlinefeed with rails?

Hi,
in my little rails application I've made a little database (create.sql) like this:

drop table if exists entries;

create table entries (
          id int not null auto_increment,
          headline varchar(100) not null,
          news text not null,
          date_available datetime not null,
          primary key (id)
         );

You see the news which is a text-type. Scaffold did a nice template with these infos where I can type in these data and save it. After that I can print these entries on the screen again with this *.rhtml:

<% for entry in @entries -%>
     <div class="blogentry">
         <h3><%= h(entry.headline) %></h3>
         <%= entry.news %> <br>
        <%= link_to 'read comments',
                     {:action => 'read_comments', :id => entry },
                     :class => 'read_comments' %><br/>
     </div>
     <div class="separator">&nbsp;</div>
<% end %>

But the problem is that I have now textformatting inside the entry.news field. E.g. how can I insert <br> after each line in entry.news?

<%= entry.news.split("\n").join("<br />") %>

or

<%= entry.news.gsub("\n", "<br />") %>

Just my 2 cents, but I strongly recommend:

<%= CGI::escapeHTML(entry.news).gsub("\n", "<br />") %>
<%= CGI::escapeHTML(entry.news).split("\n").join("<br />") %>

or

<%= h(entry.news).gsub("\n", "<br />") %>
<%= h(entry.news).split("\n").join("<br />") %>
