Hi - I'm trying to capture the value that's throwing a uniqueness error (or for that matter, any other type of built-in validation) to display it in the :message option. Here's what I tried (didn't work)

# inside the model
validate_uniqueness_of :name, :message => "#{name} has already been taken" # also tried using #{:name}

I could use a custom validation, but this beats the point of using something that's already integrated into AR. Any thoughts? thanks.
