Hi,

I really don’t understand :

In a partial, I have a collection “@users”, in wich I included  
“calls” : User.all(:include =\> :calls") in my controller.

So, in the partial, I have something like :

\<% @users.calls.each{|call|%\>  
\<%=h call.from %\>  
\<% } %\>

And the error is that i can’t get nil.from.  
How a this could be nil ?

If you rename the call variable in your block to, say, phone\_call, does  
that  
make a difference? I can’t find call on the reserved word list for Ruby  
or  
Rails, but I wonder if it’s just somehow problematic to use it.

Regards,  
Craig
