Subject: Re: exercise in DRY

So for anyone curious, here's how I wound up doing it:
(no haml just because I'm too busy learning rails and ruby already :-)

It probably could be made more dry, but this is pretty good and has the 
benefit of being written.  I haven't included the controller, because 
its a bit more complex, dealing with different databases of anonymous 
and non-anonymous users..

==== _agree_field.erb ====
<% #logger.debug "view agree: " + tweet.votedOn.to_s -%>
<% if tweet.votedOn != nil -%>
  <% if tweet.votedOn == 1 #agree %>
    <% agree = "#{tweet.agree_count - 1}<strong> + 1</strong>" %>
    <% disagree = tweet.disagree_count.to_s %>
  <% elsif tweet.votedOn == 0 #disagree%>
    <% disagree = "#{tweet.disagree_count - 1}<strong> + 1</strong>" %>
    <% agree = tweet.agree_count.to_s -%>
  <% elsif tweet.votedOn == 2 #neutral -%>
    <% agree = tweet.agree_count.to_s -%>
    <% disagree = tweet.disagree_count.to_s %>
  <% end %>
  <span class='agree'><%= agree %> </span>
  &ndash;
  <span class='disagree'><%= disagree %></span>
<% else -%>

    <span class="agree">
      <%= link_to_remote('Agree', :update => "#{tweet.dom_id}_c", :url 
=> "/tweets/agree/#{tweet.id}?agree=true") %>
    </span>
    <%= link_to_remote('&ndash;', :update => "#{tweet.dom_id}_c", :url 
=> "/tweets/agree/#{tweet.id}")%>
    <span class="disagree">
      <%= link_to_remote('Disagree', :update => "#{tweet.dom_id}_c", 
:url => "/tweets/agree/#{tweet.id}?agree=false")%>
    </span>

<% end -%>
