Hello all, I''m developing an application which allows users to browse
items for sale...
Using the url localhost:3000/browse/by_type/2 (2 is the id of the
category they are in)
Displays the information I want, however localhost:3000/browse/by_type/
will display an error page (becuase the id param is not set)
in my by_type.rhtml view, how to i check to see if the param is set? and
if not display a message?
Also similar question: I have a Property model where I use
@properties = find(:all, :condition["type_id = ?",
@param[''id'']])
How do I display a "no items found message" if @properties is empty
(ie:
no products for that category)
Thanks!
