Hi Colin, yes something like what you've proposed would work. This is the most
concise syntax I could come up with to get your suggestion working.
Media.scoped(:conditions => (name.blank? ? {:name => name.downcase!} : {}))
My suggestion (below) was to illustrate that you could have something that
looks like a named scope (dvds) actually be a method. At some point the logic
you need to apply may not fit nicely into a single named_scope call and I find
this to be a good way to handle these situations.
