Hi,
is there any function in ruby like print_r in php.
i want to debug variable/collection/session array in browser.
if i use puts it give nothing
to_yaml (as in myArray.to_yaml) works for most needs.
it does not print anything in browser i am using it like: @job.to_yaml session.to_yaml in rhtml
what to do 
Try this in your view.
<%= @job.to_yaml %> <%= session.to_yaml %>
Or use the logger from the controller (my favorite approach) like this
logger.debug @job.to_yaml
Then just check the development log for the YAML version of the array.
