I sit possible to write it in one line ? Array init + Array loading
I am always writing it in 2 lines : ( Array init then loading the
array )
@providers = []
@authentications.map {|authentification| @providers <<
authentification.provider }
Is there any Ruby writing for writing just one line ?

migrations in rails?
Are migrations used only when you''re making changes to a database? Does
it just allow the developer to avoid using raw SQL when working with
databases?
