I got this out of a book so I'm pretty sure it should work:
class Folder < ActiveRecord::Base
def validate
if self.find_by_name(name)
errors.add("folder by that name exists")
end
end
end
but when I validate:
<%
f = Folder.find_by_name("New Folder")
%>
<%= f.valid? %>
I get this:
undefined method `find_by_name' for #<Folder:0x40a125f4>
Any ideas?
Thanks
