Re: [Rails] Re: How to pass values to named scope?

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.
