Simple Question - getting first field

Ruby
1

Hey, I have a question.

I am loading up radio buttons in a form based from db. I want the first radio button that shows up to be selected. For simple demo I am just going to use <li>s.

<% foo.bar.each do |baz| %>

<li><%= baz.bleh %></li>

<% end %>

In that example how do I make the first <li> have class=“first”?

I’d use each_with_index instead of each, and then just test for i==0.

yes you can use the index of the object to get the desired result

Or you could use:

baz == foo.bar.first
