I followed the sample code in AWDR 2 like this:

store\_helper.rb

def hidden\_div\_if(conditions, attributes = {})  
if conditions  
attributes[“style”] = “display:none”  
else  
attr = tag\_options(attributes.stringify\_keys)  
“\<div #{attr}\>”  
end  
end

store.html.erb

\<%= hidden\_div\_if(@cart.items.empty?, :id =\> “cart”) %\>  
\<%= render(:partial =\> “cart”, :object =\> @cart) %\>

when the cart is empty, the “

” snippet is not  
displayed there.

could anybody help me with this?

sorry for the mistake, I didn’t read the sample code carefully.

there’s no “if…else…end” structure in this method. 🙂
