Thanks , you're right, :db_file is defined, and the line runs well... my concern was about the 'fetch' function which returns a string.. it seems to return the second string argument if the first is not defined ... but is it a Ruby function or a Rails function .... I know a anArray.fetch( aString) but not this one ....
