How can I change the tags/css class of some dynamic text based on output from a helper?

I have a repeated line which outputs something like: Call John Jones in -3 days (status)

I have a helper called show_status(contact,email) which will output whether that particular email had been sent to that particular contact.

If it is "sent," then that entire line s开发者_高级运维hould show up as "strike out."

Similarly, if the number of days is -3 (<0), the line should be formatted in red.

Here's my hack, but there must be a cleaner way to put the logic into the controller?

I hard-code a value that wraps around the lines I want formatted, and assign the value based on a separate call to the same helper:

<% for call in @campaign.calls %>
        <% if !show_call_status(@contact,call).blank? %>
           <%= strike_start = '<s>'%>
           <%= strike_end = '</s>' %>
        <% end %>
        <p>
            <%= strike_start %>
            <%= link_to call.title, call_path(call) %> on 
        <%= (@contact.date_entered + call.days).to_s(:long) %> in <%= interval_email(@contact,call) %> 
        days 
        <%= make_call(@contact,call) %>
        <span class='status'><%= show_call_status(@contact,call) %></span>  
        <%= strike_end %>   
        </p>
<% end %>

I guess what I'd like to do is not have the if statement in the View. Not sure how to do this.

Basically, I would put a class on the p tag based on the status and have the CSS decide what needed to be done.

So the view:

<% for call in @campaign.calls %>
  <p class="<%= call_status_class(@contact, call) %>">
    <%= link_to call.title, call_path(call) %> on 
    <%= (@contact.date_entered + call.days).to_s(:long) %> in <%= interval_email(@contact,call) %> 
    days 
    <%= make_call(@contact,call) %>
    <span class='status'><%= show_call_status(@contact,call) %></span>  
  </p>
<% end %>

And another helper:

def call_status_class(contact, call)
  # do what you have to do to figure out status
  if overdue
    return 'overdue'
  elsif called
    return 'called'
  else
    return 'standard'
  end
end

Then in CSS:

.standard {
  ...
}
.overdue {
  color: red;
}
.called {
  text-decoration: line-through;
}

Pick and choose. I can't really give you full fledged solution without seeing all the helper functions. Hope this helps.
