We have a convention here at Songkick (after a great deal of debate)
that it's OK to refer to key domain concepts like Concerts, Artists,
Venues etc by their Ruby class name from within the scenario. Thus our
thing_to_model function is always a matter of just calling
I greatly prefer this to having any kind of custom mapping - it
promotes the 'ubiquitous language' that Eric Evans talks about in the
original DDD book.
Maybe it's different when you're working in another language though -
I guess it's preferable to use English names for classes etc, is it?
