This is fine approach, but it will display errors mixed with warnings in no particular order, and that is not good in my opinion. I prefer messages sorted in order of decreasing severity: [:error, :warning, :notice, :message]

I have some code that does it, but I written it at the very beginning of studying ruby/rails, so I will not posit it here, it is not pretty ;)
