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

[Gabor Szabo]

Have you checked the content when you "view source" in the browser?
I had cases when my code did not show up because I had some HTML issues.
I wasted so much time till I figured out the content is there just hidden.

My example is stand-alone using Template::Toolkit,
when using Dancer you don't need that, you only need to enable it in the
config file
and you pass your data to the "template" function.

The TT part is almost identical though I think in Dancer we use <% for tags
and not
the default [% as in my example.
