tempfile generation issue from user generated filename in ruby/OS
We used a super simple code in ruby to generate tempfiles with dynamic filename.
temp_file = Tempfile.new([title, '.pdf'])
where title is a variable value (Input taken from user).so if your insert special or not allowed/expected character as a filename in any Operating system this code will fail. Well this is not related to Ruby directly as its a filename constraint in every Operating system but it happened to us via Ruby code.
temp_file = Tempfile.new([title.gsub(/[^\w\.]/, '_'), '.pdf'])
Pretty simple solution to remove/Replace not allowed values there. This is very minor thing to correct as well to take notes, but we had exception from production and that is not acceptable at all.
