[dancer-users] Only even items

Thanks you, very much,  It's works

but I not really understand why with hash , half of result go to keys 
and other to values
and how template toolkit do the relation between database fiels and 
values  with simple list ?

for my point of view , a simple "complet" example will be good idea in 
documentation.
complet = perl part AND ttk part

bye
