Ruby / Rails alternative to PHP print_r() and var_dump()
Both PHP functions provides information about a variable passed as argument. It is often used in development to get quick and human-readable info about array or object. If you are using Rails you can use DebugHelper’s debug(object) helper function. Note that helpers are available only in views. In controllers, models and other Ruby code you can use ‘puts YAML::dump(object)’ method to get readable info about object.
