Question

I have:

@layout = [:maincol => ['a'], :sidecol => []]

then I want to loop and get:

<div class="maincol"><div class="a"></a></div>
<div class="sidecol"></div>

How do I do it?

Answer 1

First of all, this is a ruby question not ruby-on-rails. Secondly there are a few naming conventions in Rails and @layout would certainly confuse other programmers as well as :maincol and :sidecol is a rather bad naming and they should be what ever the model behind is.

<div class="maincol"><% @layout[:maincol].each do |element| %>
   <%= "<div class="%s"></div>" % element %>
<% end %></div>
<div class="sidecol"></div>
