Wrap error_messages_for() call when no instance var present
I am trying to put some smarts around a call to
<%= error_messages_for %>
so that when I first come into this page i.e. when my instance variable
@target_list has not been defined yet, the page doesn''t break.
I''m doing this:
<% if @target_list? %>
<%= error_messages_for ''target_list'' %>
<% end %>
I get a syntax error on line 1.
