I am looking at a ruby script and testing it...
I don't fully understand the following line of code :
database = YAML::load_file("config/#{fetch(:db_file,
'database.yml')}")
=> fetch(:db_file, 'database.yml') ... what's is this function
fetch() ?
I know the fetch(key, *extras) in ActiveSupport, but this is not the
case.... any suggestion ?
thanks
