You have an instance variable called "@session", which you''re using in a way that makes me think it''s a hash.> full error trace:- > ActionView::TemplateError (You have a nil object when you didn''t expect it! > You might have expected an instance of ActiveRecord::Base. > The error occurred while evaluating nil.[]) on line #61 of > app/views/layouts/main_bk_layout.rhtml: > 58: <%if @session != nil%> > 59: <table width="250" border="0" height="20" > align="right" cellspacing="0" cellpadding="0"> > 60: <%else%> > 61: <%if @session[''user''].first_name == "admin"%> > 62: <table width="290" border="0" height="20" > align="right" cellspacing="0" cellpadding="0"> > 63: <%end%> > 64: <%end%>Okay... after a second read through the confusion becomes clear. The error tells you that line 61 is the problem - and shows it is where you''re accessing "@session[''user'']" - but looking at the conditional code, you''re checking if @session is *not* nil and performing a block in that event, and then in your "else" block (where @session *is* nil), you access @session, which obviously crashes because @session is nil. I think you need to review the logical flow of the code. HTH -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
