views formatting

[atmorell]

Hello,

My messages model got a "status" field. What i would like to do is wrap <strong> around the link if message.status = new. How should such a task be sovled in RoR?

VIEW:

<% for message in @messages %>
	<li>
		<%= link_to message.subject, {:action => 'show',:id => message.id} %>
	</li>
 
<% end %>

Best regards.

The easiest and straightforward approach is just simple conditionals:

<% for message in @messages %>
    <li>
        <%= "<strong>" if message.status == 'new' %>
        <%= link_to message.subject, {:action => 'show',:id => message.id} %>
        <%= "</strong>" if message.status == 'new' %>
    </li>
<% end %>

It's a bit heavy, though, if you're using this all over the place. At that point, you might want to move the whole process into a helper (/app/helpers). Just keeps it a bit simpler:

<% for message in @messages %>
    <li>
        <%= message_link(message) %>
    </li>
<% end %>

#in a helper file
def message_link(message)
    if message.status == 'new'
        "<strong>#{link_to message.subject, {:action => 'show',:id => message.id}}</strong>"
    else
        link_to message.subject, {:action => 'show',:id => message.id}
    end
end

...something like that. There's about a billion ways to tackle this, simplify it, refactor it, etc.

Thanks. Nice with the helper example

Just for the case you are using the same method in your controller and your views you can define the method in your controller and then use helper_method :my_method to propagate it to the view.
