if statement - problems with if condition in rails -

i tried render file if true.

my code

<% if @orbituarysite.notice_display.nil? %>   <%= render 'notice_displays/form' , :remote => true %> <% end %> 

i tried in console shows true, output

1.9.3-p194 :024 > b=orbituarysite.find(1) 1.9.3-p194 :025 > b.notice_display noticedisplay load (1.4ms)  select "notice_displays".* "notice_displays" "notice_displays"."orbituarysite_id" = 1 limit 1 => nil  1.9.3-p194 :026 > b.notice_display.nil? => true  

here shows true , i'm unable render form, though have value true please tell me missing?

you have make :-

<% if @orbituarysite.notice_display.nil? %>   <%= render 'notice_displays/form' %> <% end %> 

in notice_displays/_form

<%=form_for....., :remote => true%>
