New way of calling partials on collections

You can directly call a partial on a collection of objects like this:

<%= render :partial => @users %>

This will call the partial _user.html.erb and populate a local variable ‘user’ within the partial. Then you can display the user partial in this way:

_user.html.erb:

Name: <%= user.name %> <br />
Email: <%= user.email %> <br />

The above render statement is equivalent to this code:

<% for user in @users %>
  <%= render :partial => 'user', :locals => { :user => user } %>
<% end %>
