Question

I’m new to Ruby on Rails. In my erb files, is there any reason to use the div_for helper over just typing out the <div> tags and setting the properties as HTML? What advantage is there to using div_for, and is there a recommended best practice?

Answer 1

I think the main reason people use the div_for helper is because it can accept an array of ActiveRecord objects as an argument. That way it becomes a short-hand combination of a loop iterator and a tag generator.

<%= div_for(@people, :class => "foo") do |person| %>
    <%= person.name %>
<% end %>
