[dancer-users] passing a variable to a new subroutine route

[Richard Reina]

Hi WK,

Thank you very much for the reply. Before I saw this came up with this
solution to pass the variable to the other sub/template:

  # take them to the add_sport (but with the id no)
    hook 'before' => sub {
          var S_id => $select_id;
          request->path('/sport_add')
    };

    redirect '/sport_add';

It actually worked but I was wondering if doing it this way with hook and
redirect is a bad idea?  Also, I was wondering why it's a bad idea to print
input from dancer to the console?  Does it produce a security vulnerability
or is it merely disruptive to dancer?

Thanks
