Ruby on Rails

Thanks, I will try this!

I wonder: Where do I find a specification for this feature? I guess
Rails automatically generates this kind of find_by_... functions for
each attribute in my model, which as "uniqueness" set. Where is this
documented? My biggest problem with rails is getting from the API docs
the information I need.

Just for my understanding: Could you also please explain, why my
original (complicated) version failed?
