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) %]

Hi Dancers,
I am pretty new to Dancer and really like the light nature of the
framework.
I am trying to create a route which will show data from a MongoDB
collection and struggling with the syntax.
I have the following in my app:
sub connect_mongo {
my $client = MongoDB->connect('mongodb://a.b.c.d') or die
"Error connecting to Mongo";
my $db = $client->get_database( 'lfi-perl' );
return($db);
}
get '/mongo' => sub {
my $db = connect_mongo();
my $docs = $db->get_collection( 'Test-Collection' );
my $all_docs;
template 'show_mongo.tt <http://show_mongo.tt>', {
'entries' => $all_docs = $docs->find(),
};
};
Then in my view the following:
[% FOREACH id IN entries.keys.nsort %]
[% entries.$id._id %]
I am not able to see any data in my view but am also not seeing any
errors.
Any examples of getting data from Mongo in Dancer would be really helpful.
Thank you in advance,
Gavin
