Not trying to do anything other than experiment. I was playing with for 
the first time today and the book I'm readin said the view had access to 
the controller's instance variables. I was trying to find out what other 
instance variables/values the view could access. in the erb file id put 
this code in:
<% self.instance_variables.each do |var| %>
<%= h(var) %>
<%end%>

And it gave me a list of the instance variables without values... just 
trying to learn by experimenting.
