[dancer-users] How tod displaye aMulti Dimesional Hash in Template Toolkit

[Richard Reina]

Hi Gabor,

Thank you very much for your help. I appreciate your answer and all
the wonderful tutorials at perlmaven, but so far I am unable to get
this answer to work for me. My my hash %season seems to look the same
as your %payload but when I try your solution only the name of the
player is displayed. I do not use 'use Template'; in my backend code
and am not really sure what the exact role of create.pl, is it for
teaching purposes or is there a step within it that I must apply to
get my %season to look like your %payload before I return it to my
Dancer app? I will continue to experiment with your solution and try
to find a place where I can post exactly what I am getting as a
result.

Thanks again,

Richard
