[dancer-users] Question on MongoDB and Dancer

[Richard Jones]

I've been caught by that before. Try [% entries.$id.item('_id') %]. For 
some reason (would interested to learn what), TT doesn't seem to be able 
to cope with leading underscores in data structures. You can prove 
entries contains data using:

[% USE Dumper(Indent=1) %]
[% FOREACH id IN entries %]
   <pre>[% Dumper.dump(id) %]</pre>
[% END %]

or just [% Dumper.dump(entries) %]
