[dancer-users] list order from a hash

[Attila Bárdi]

Hey,

use the manual Luke!:)

http://www.template-toolkit.org/docs/manual/Directives.html <http://www.template-toolkit.org/docs/manual/Directives.html>

Search for sort.

<% FOREACH ID IN Jobs.keys.sort %>
<% FOREACH ID IN Jobs.keys.nsort %>

sorted alphabetically ( sort ) or numerically ( nsort )

Best regards,
Attila

> And it works great. Except for one thing, the list is not in order by name. I have read more than a few posts about how once you save a query as a hashref that the order is lost. Most of those posts suggested fetching as a arrayref instead. However, I have no idea how to do that and then display it in a select like the above code does. So I wanted to see if somebody perhaps knows of a not too complicated of a solution to get the select list into alphabetical order by name.
