[dancer-users] Question on MongoDB and Dancer

[Gavin Colborne]

Thanks Richard and everyone,

I added the ".item" so my view shows: [% entries.$id.item('time') %] I
still don't see any results :(

I now see in my terminal the following: Argument "client" isn't numeric in
numeric comparison (<=>)
Which from what I can tell from Gabor's great site
https://perlmaven.com/argument-isnt-numeric-in-numeric is some numeric
operation problem.

Do you have any examples of controllers passing Mongo data to views so I
can compare?

My code so far - perhaps the controller is the issue?

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', {
         'entries' => $all_docs = $docs->find(),
     };
};


Appreciate your help,

Gavin
